Best IB Schools in Bangkok | Curriculum & Fees 2026-2027

The IB has a smaller footprint in Bangkok than the British curriculum but a notable one, with around a dozen schools authorized to run at least one IB programm and a handful running the full continuum from age 3 through Diploma. The appeal is the breadth. Diploma students keep six subjects across language, sciences, humanities, and maths until age 18, rather than narrowing to three or four. The Diploma is recognized by every major university system worldwide: Oxbridge, the Ivy League, the Russell Group, the Group of Eight in Australia, the leading institutions in continental Europe and across Asia.

The trade-offs are worth knowing before you commit. The Diploma is a rigid structure: six subjects plus three core components (Theory of Knowledge, the Extended Essay, and Creativity Activity Service), with no option to drop the load and specialize. The final two years are genuinely heavy. The system rewards children who can hold multiple deadlines at once and write at length under their own steam. Neither of those things is a dealbreaker, but both are worth factoring in for your child specifically.

In Bangkok, annual tuition at IB schools ranges from roughly 400,000 to over 1,000,000 THB depending on tier. The real cost runs 20–35% higher once you add registration, capital fees, transport, uniforms, and IB exam fees in the Diploma years. Popular entry points, the start of PYP, the start of MYP, and Year 12 for the Diploma, fill months in advance. The earlier you start the process, the more options you have.

This guide walks through the full picture in the order parents actually need it. We don't rank schools or tell you which one to choose, that's not what we do. We show you the structure, so you can shortlist with confidence and compare specific schools using the tools on bkkschools.com.

"Every school decision deserves real answers."

Start here

If you have just started researching the IB and you already feel a bit lost in acronyms, you are not behind. The system genuinely uses more abbreviations than most curricula (PYP, MYP, DP, CP, TOK, CAS, EE, IA, EAL), and Bangkok schools each describe their version slightly differently. The point of this guide is to give you, in one place, the structure beneath the marketing language so you can compare like for like.

We assume nothing. If you already know the IB inside out, skip to costs, or admissions. If you are starting cold, the next paragrahs will save you a lot of evening googling.

The 30-second version

The IB is not one thing. It is four programms that schools can adopt individually or stack: the Primary Years Programm (PYP, ages roughly 3 to 12), the Middle Years Programm (MYP, ages roughly 11 to 16), the Diploma Programm (DP, ages 16 to 19), and the Career-related Programme (CP, also ages 16 to 19). The DP is by far the most internationally recognised, and the one most parents mean when they say "IB". Schools in Bangkok run any combination: some run all four, some run only the DP at sixth-form age, some run PYP and MYP but switch to A-Levels for sixth form.

Three things to know up front

• One. The Diploma Programm requires six subjects plus three core components (TOK, CAS, the Extended Essay). Students cannot drop subjects to specialize; they finish with a balanced load. This is the structural feature most often loved or resented.

• Two. The IB is criterion-referenced and graded on a 1 to 7 scale per subject, with a maximum total of 45 points (42 from subjects plus 3 from the TOK and Extended Essay matrix). Universities understand it.

• Three. Authorization matters. A school that says it "follows IB philosophy" or is a "candidate school" is not the same as a school authorized to offer the IB.

A 5-question self-check

If you answer yes to three or more of the following, the IB is worth shortlisting. If you answer yes to all five, it is probably the most natural fit and you should be looking carefully at the Bangkok IB schools first. If you answer yes to fewer than two, look at British, American, or another curriculum first and circle back to IB only if those do not work.

1. Is your family likely to move countries again before your child finishes school?

2. Does your child resist narrowing down to a small number of subjects, or does the idea of dropping all sciences (or all humanities) at age 16 worry you?

3. Are you applying to universities across more than one country (e.g., UK and US, or UK and Asia)?

4. Do you want a curriculum where critical thinking, research skills, and a written thesis are built in, not bolted on?

5. Are you willing to accept a heavier final-two-years workload in exchange for breadth?

Year groups and ages

The IB does not use "year" or "grade" labels of its own; it uses programme names and lets each school adopt the year-numbering convention of its host country or its dominant cultural orientation. In Bangkok, this means an IB school can label the same age group as Year 7, Grade 7, or Class 7 depending on whether the school leans British, American, or international-default. The conversion table below uses the most common Bangkok pattern.

A practical note: the IB Diploma is two years, normally taken at ages 16 to 18. The first year is sometimes called DP1 or DP Year 1; the second is DP2. Schools running the British year system call these Year 12 and Year 13. Schools running the American grade system call these Grade 11 and Grade 12. They are the same students at the same age.

Common terminology confusions

MYP Year 5 is not the same as British Year 11

They sit at the same age, but the assessment is different. A British Year 11 student takes IGCSE or GCSE exams. An MYP Year 5 student takes MYP-specific assessments, which can include eAssessments and Personal Project work but are not externally graded in the same way as IGCSEs. Universities do not use MYP results for entry; they use the Diploma Programm grades two years later. We come back to this in Section 4.

"IB" almost always means the Diploma Programm

When parents in Bangkok say "is your school IB", they usually mean: does it offer the Diploma Programm at sixth-form age. A school can be PYP-authorized but not run the DP at all, in which case calling it an "IB school" is technically true but practically misleading. When you ask a school, ask which IB programms they are authorized to offer, end to end.

Pre-nursery and nursery before PYP

The PYP officially begins at age 3 in most authorized schools, but many Bangkok schools accept children from age 2 in a pre-nursery class that runs alongside, but not formally inside, the PYP framework. If your child is younger than 3, ask the school whether the early years are a true PYP class or a feeder class with PYP elements. The fees and the daily structure can differ.

How the system actually works

The IB is built on four programmes that progress with age. The Primary Years Programme (PYP) covers ages 3 to 12 and is inquiry-led, with no national-style subject divisions in the early years. The Middle Years Programme (MYP) covers ages 11 to 16 and introduces eight subject groups while keeping the inquiry framework. The Diploma Programme (DP) covers ages 16 to 19 and is the formal university-entry qualification, structured around six subjects and three core components. The Career-related Programme (CP) is also for ages 16 to 19 but combines DP-style subjects with career-focused study and a service-learning element; it is far less common in Bangkok than the DP. We treat each in turn.

PYP: ages 3 to 12

The PYP is organized around six "transdisciplinary themes" that recur each year and frame the inquiry units. The themes are: Who we are, Where we are in place and time, How we express ourselves, How the world works, How we organize ourselves, and Sharing the planet. Within these themes, children study six subject areas (language, mathematics, science, social studies, arts, and personal/social/physical education), but the daily timetable is typically integrated rather than blocked into single-subject lessons in the way British or American primary schools do.

What is taught: literacy and numeracy fundamentals, second language acquisition, conceptual science, social studies grounded in cultural understanding, arts, and physical education. The host language (Thai, in Bangkok) is taught at varying intensities, which we cover in Section 9. The PYP also has a structured emphasis on "learner profile" attributes (inquirer, knowledgeable, thinker, communicator, principled, open-minded, caring, risk-taker, balanced, reflective) that schools assess alongside subject content.

What is assessed: ongoing teacher assessment against PYP criteria, no external exams, and a culminating "Exhibition" project in the final year of PYP (typically Year 6, age 11). The Exhibition is a student-led inquiry that takes weeks to complete and is presented to the school community. It is taken seriously by IB schools and is often what parents see at PYP open days.

The pace: gentler than a typical British or East-Asian primary in early years (less direct phonics drilling, more inquiry), with formal academic skills layered in across the years. By the upper PYP, the workload approaches that of other systems but is structured around projects rather than weekly tests. What is compulsory: all six subject areas plus the host-country language. What is optional: the additional second language at some schools.

MYP: ages 11 to 16

The MYP runs for five years (sometimes labelled MYP 1 to MYP 5). It bridges the inquiry-led PYP and the formal Diploma Programme. Students study eight subject groups: Language and Literature (typically English), Language Acquisition (a second language), Individuals and Societies, Sciences, Mathematics, Arts, Physical and Health Education, and Design. Each year, every student takes at least one subject from each group; schools structure how that maps onto the timetable.

What is taught: same eight groups for five years, with depth increasing each year. Students also work on "interdisciplinary units" each year that bring two or more subjects together around a theme. The MYP is more academically structured than the PYP but retains the conceptual framing: students learn through key concepts (e.g., systems, change, identity) and global contexts.

What is assessed: criterion-referenced assessment in every subject, internally moderated. In MYP Year 5, students complete a Personal Project, an extended individual inquiry that takes most of the year and is externally moderated by the IB. Some schools also offer optional MYP eAssessments in MYP Year 5, which are externally marked and produce an IB-validated MYP Certificate. eAssessments are not universally taken; many Bangkok IB schools choose to run them, others choose not to. Ask the school directly.

The pace: builds steadily across the five years. MYP Year 4 and 5 are noticeably heavier than the early MYP. What is compulsory: all eight subject groups every year, plus the Personal Project in Year 5. What is optional: eAssessments, additional language tracks, some specific course branches within the eight groups.

DP: ages 16 to 19

The Diploma Programme is the two-year qualification that most parents have in mind when they say "IB". It is the most structurally demanding part of the system and the one with the heaviest direct effect on university entry. Students choose six subjects, three studied at Higher Level (HL) and three at Standard Level (SL), one from each of six groups: Studies in Language and Literature, Language Acquisition, Individuals and Societies, Sciences, Mathematics, and the Arts (with Group 6 substitutable for an additional subject from Groups 1 to 5).

Alongside the six subjects, every Diploma student completes three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). These are not optional add-ons. They are required for the full Diploma. Section 4 walks through what each one involves in detail, because they shape the workload more than parents expect.

What is taught: six chosen subjects in depth at HL, in good breadth at SL, plus the core components woven across both years. Higher Level subjects are taught for around 240 hours over the two years; Standard Level subjects for around 150 hours. HL subjects go further into content and assessment than SL.

What is assessed: external written exams at the end of DP Year 2 in every subject, plus internal assessments (IAs) in each subject during the two years, marked by the school and externally moderated. The TOK essay is externally marked. The Extended Essay is externally marked. CAS is internally tracked and required for completion, but is not graded for points. Subjects are graded 1 to 7. The maximum total is 45 points: 42 from subjects (six subjects, each 1 to 7), plus up to 3 from the TOK/EE matrix.The pace: heavy and front-loaded with internal assessment deadlines. The first year of DP is typically the steepest jump in workload many students experience. The second year layers exam preparation on top of the Extended Essay deadline (usually due early in DP Year 2) and the final TOK assessment. What is compulsory: six subjects, three HL and three SL, plus TOK, EE, and CAS. What is optional: which subjects to take within each group, whether to take an additional language as a Group 6 substitute, and which specific HL and SL split to choose.

CP: ages 16 to 19

The Career-related Programme is the IB's career-focused alternative to the Diploma Programme at the same age. Students take a minimum of two DP subjects, plus a career-related study (provided by an external provider, e.g., BTEC or similar vocational qualifications), plus the CP core (a Reflective Project, Personal and Professional Skills, Service Learning, and Language Development).

The CP is far less common in Bangkok than the DP. We flag it because some schools list it among their offerings, but in practice the cohort sizes are small and the subject ranges available locally are narrower. If the CP is genuinely a fit for your child, ask which specific career-related qualifications the school partners with, and how many CP students they had graduate in the most recent cohort. A CP cohort of three is very different from a CP cohort of thirty.

The exams, qualifications, and the DP core

The IB produces a small number of formal credentials, but the headline one (the IB Diploma) is the only one that drives most university decisions. We start there, then cover the others, then walk through the three Diploma core components (TOK, the Extended Essay, and CAS) in their own subsections, because they are not exams in the traditional sense but they structurally shape what an IB sixth form looks like.

The qualifications, listed plainly

• PYP Exhibition: a school-level culminating project at age 11. Not a formal external qualification.

• MYP Personal Project: a year-long individual inquiry in MYP Year 5 (age 15 or 16). Externally moderated by the IB.

• MYP Certificate: optional, awarded to students who complete the full MYP including eAssessments. Not universally offered or taken.

• IB Diploma: the formal sixth-form qualification. Awarded for completion of six subjects plus the three core components, with a minimum point total and various other conditions.

• IB Course Results: awarded to students who take some DP subjects but do not complete the full Diploma. These show on the same transcript but do not constitute the Diploma award.

• CP Certificate: awarded for completion of the Career-related Programme.

The DP grade scale

Each of the six DP subjects is graded 1 to 7. Subject grades are summed for a maximum of 42 points. Up to 3 additional points come from a matrix combining the TOK and Extended Essay grades. CAS is required for the Diploma but does not contribute points. The maximum total is therefore 45 points. To be awarded the Diploma, students must meet a published minimum (currently 24 points) plus several conditions, including no fail-grade subjects, completion of CAS, and successful completion of TOK and the Extended Essay. [VERIFY] all current pass conditions against the IB's published Diploma Programme assessment regulations for the year your child will sit the exams.

On A-Level and AP equivalences: these are rough approximations only. Universities do not convert grades; they specify their entry requirements directly in IB points, and they treat the IB Diploma on its own terms. The table is here to help parents who already understand A-Levels or APs orient themselves, not to suggest that grades translate one to one.

How universities recognize the Diploma

The IB Diploma is recognized across the UK (UCAS publishes IB tariff equivalents), the US (most universities accept it directly, often awarding college credit for HL grades of 5 or above), Australia (each state has its own conversion table from IB points to ATAR ranks), continental Europe (recognized under the Lisbon Recognition Convention and through specific bilateral agreements), Asia (most major Asian universities including in Singapore, Hong Kong, and Japan accept it, though entry requirements vary), and Thailand (international and English-medium programmes at the larger Thai universities, including the Chulalongkorn International Programme and Mahidol International, routinely accept IB Diploma scores; Thai-medium programmes generally require additional Thai-language qualifications regardless of curriculum).

Internal assessments and external exams

Almost every DP subject combines two assessment elements: external exams sat at the end of DP Year 2, and internal assessments (IAs) carried out across the two years. IAs are marked by the school and externally moderated by the IB, which means a sample of every cohort's work is checked by an IB examiner, and the school's marks may be adjusted up or down accordingly. The split varies by subject. In sciences, IAs typically count for 20 percent of the final grade. In Visual Arts, IAs make up the majority. Ask each school how its internal assessment moderation has tracked over the past few years, because consistent moderation is one signal of teaching quality.

The DP core: TOK, Extended Essay, CAS

The Diploma is not just six subjects. Every student also completes three core components, and the way they fit together is one of the things that makes the IB structurally different from A-Levels or the American high school diploma. Treat this section as essential reading; the core is what most marketing skips over but what most current IB students will tell you defines their experience of the programme.

Theory of Knowledge (TOK)

TOK is a course in epistemology, taught across both years of the Diploma. The central question is: how do we know what we know? Students explore how knowledge is produced, justified, and contested across different "areas of knowledge" (the natural sciences, history, the arts, mathematics, human sciences, indigenous knowledge systems) and through different "ways of knowing" (reason, language, perception, emotion, intuition, faith, imagination, memory). The course is roughly 100 hours over the two years.

Assessment is in two parts: a TOK exhibition (an internal commentary on three real-world objects connected to a knowledge question), and a TOK essay of 1,600 words on one of six prescribed titles released by the IB each year. The essay is externally marked. Together, the exhibition and essay produce a TOK grade of A to E. This grade combines with the Extended Essay grade in a matrix that awards up to 3 of the 45 total Diploma points.

What it actually feels like for students: TOK divides opinion. Some students find it genuinely formative, the first place they have been asked to think rigorously about how disciplines differ in what they count as evidence. Others find it abstract and burdensome on top of an already heavy subject load. The teaching makes a large difference. A school with experienced TOK teachers tends to produce students who speak about TOK with engagement; a school where TOK is taught by a rotating cast of subject teachers without a TOK specialist tends to produce more grumbling. When you visit a school, ask who teaches TOK and how long they have done so.

The Extended Essay (EE)

The Extended Essay is a 4,000-word independent research paper, written across the two years of the Diploma. Each student chooses a topic in one of their six DP subjects (or in a permitted interdisciplinary World Studies area) and writes the essay under the guidance of a school supervisor. The supervisor mentors but does not co-write. The essay is externally marked, graded A to E, and combines with the TOK grade in the matrix mentioned above.

The EE is genuinely demanding. It is the closest most secondary students come to a small-scale university dissertation: original research question, literature review, methodology, evidence, argument, conclusions, citations. Universities (particularly in the UK) reference the Extended Essay positively in admissions, and a strong EE in a related subject can support a competitive university application. The deadline is typically late in DP Year 1 or early in DP Year 2, depending on the school's internal scheduling. The version we wish someone had given us: the students who do well on the EE start it early and stay in regular contact with their supervisor; the ones who suffer leave it until DP Year 2 and try to write it alongside exam preparation.

Creativity, Activity, Service (CAS)

CAS is the third core component. It is not graded and it does not contribute points, but it is required for the full Diploma. Students complete a portfolio of activities across the two years that span three strands: creativity (any pursuit of creative thinking outside academic subjects), activity (physical exertion contributing to a healthy lifestyle), and service (unpaid voluntary engagement that benefits a community). Students plan, document, and reflect on their CAS engagement, and complete at least one substantial CAS project that runs for a sustained period.

What CAS looks like in practice in Bangkok: schools vary widely. Some run structured CAS programmes with established community partnerships (e.g., recurring service work with specific charities, in-house creativity programmes, organised activity strands) and a dedicated CAS coordinator who tracks every student's progress. Others leave CAS substantially to the student to construct from their existing extracurricular life, with lighter institutional support. Both can produce good outcomes, but the experience differs. Ask schools how they support CAS, who the CAS coordinator is, and what proportion of students typically complete CAS on time.

IB vs other curricula, and how to actually choose

We will be honest about something most school marketing avoids saying. No curriculum is "better" in the abstract. The IB is not better than A-Levels. A-Levels are not better than the American system. The Australian HSC is not better or worse than any of the above. Each is a coherent design with strengths and trade-offs, and the right curriculum for a particular child depends on the child, the family's likely future, the universities they may apply to, and the specific schools available locally. This section is a comparison tool. We do not tell families which to choose.

Structural comparison: IB DP vs A-Levels vs American high school diploma

The three curricula most often compared at sixth-form age in Bangkok are the IB Diploma, the British A-Level (with IGCSEs preceding), and the American high school diploma (typically supplemented with AP courses and SAT or ACT for university entry). Other systems exist (Australian, French, Singaporean) and we touch on them where relevant, but the structural comparison below is the one most parents agonize over.

"Better fit if your child..."

The structural comparison above is the engineering view. The next table is the parent view: which curriculum tends to suit which kind of student. These are tendencies, not laws.

Difficulty: is the IB really harder?

There is no clean answer to this. The honest version: the IB Diploma demands consistent work across more subjects and core components than A-Levels do, and consistent work across two years rather than the steadier four-year pacing of the American system. Students who are strong all-rounders often find the IB challenging but manageable. Students with sharp peaks and troughs across subjects often find it harder than A-Levels would have been. Students who struggle with extended writing tend to find TOK and the Extended Essay demanding, regardless of overall academic ability.

What the IB does not do: it does not let a student drop their weakest subject and concentrate firepower on three strengths the way A-Levels do. This is the clearest structural difference and the one parents should weigh most carefully when assessing fit.

Switching mid-school

Switching from MYP into a British IGCSE programme at the start of Year 10 is reasonably common in Bangkok and usually works because the academic content overlap is high. Switching the other way (from IGCSE into MYP Year 4 or 5) is also possible but depends on the receiving school's flexibility. Switching from A-Levels into the Diploma after Year 12 has begun is structurally very difficult, because the IB front-loads its assessment from day one of DP Year 1. Switching from the Diploma into A-Levels mid-Year 12 is also difficult, although schools occasionally make it work. The general rule: change curriculum at year-group transitions, not mid-year and not mid-programme.

Schools in Bangkok that offer dual pathways

Some Bangkok schools offer parents a choice of curriculum at sixth form, typically IB Diploma or A-Levels, occasionally IB Diploma or American Advanced Placement. This dual-pathway model means the school runs both qualifications in parallel and students choose, often at the end of MYP Year 5 or Year 11. The advantage is the option to defer the decision until you have seen how your child develops; the disadvantage is that running two pathways requires the school to staff and resource both, and the smaller cohort on whichever pathway is less popular can mean fewer subject options.

Which curriculum suits which university destination

If UK universities are the priority, A-Levels and the IB Diploma are both well understood, with UCAS publishing direct tariff conversions for the IB. Some UK universities prefer A-Levels for specific subjects (medicine and engineering are common examples) but the Diploma is broadly accepted. If US universities are the priority, the IB Diploma is well regarded; the American high school diploma supplemented by APs is the most natural domestic match; A-Levels are also accepted but require some explanation in admissions context. If Australian universities are the priority, the IB Diploma converts to ATAR ranks via published state-level conversion tables and is well regarded. If Asian universities (Singapore, Hong Kong, Japan) are the priority, the IB Diploma is widely accepted; A-Levels are also recognized; the American diploma is recognized but requires SAT or ACT alongside. If Thai universities are the priority, the IB Diploma is accepted by international and English-medium programmes at the major Thai universities; Thai-medium programmes typically require Thai-language qualifications regardless of secondary curriculum.

What it really costs in Bangkok

Cost is where families spend the most evenings on spreadsheets and the most hours in admissions calls trying to compare like with like. The IB does not have a fixed price; what you pay depends on the school running the programme, not the programme itself. Bangkok IB schools span almost the full range of international school tuition in the city, from mid-tier annual fees at the lower end to the most expensive tier of schooling in Bangkok at the upper end. We split the market into three directional tiers below.

The three tiers

Examples of schools in each tier

The names below are concrete reference points so you can map the tier ranges above onto schools you are likely to encounter in your search. Inclusion is based on current IB authorization status published by the IB Organization and on each school's published fee schedule at the time of writing. It is not a ranking, not a shortlist, and not a placement guide. We have grouped schools by where their published DP-year tuition currently sits, not by reputation, age, or campus size. Fees move every academic year. Always confirm the current figure with the school before using it for any decision.

Tier 1 examples: premium IB schools

Schools whose published DP-year tuition typically sits at or above the 900,000 THB mark, often closer to or above 1,000,000 THB once mandatory annual fees are included. These tend to be the longest-authorized IB schools in Bangkok with full PYP-MYP-DP continuums and the largest published campus footprints.

• NIST International School (Sukhumvit, Wattana). Thailand's first not-for-profit full IB continuum school, authorized since 1999 across PYP, MYP, and DP. Annual tuition is published in a band that runs roughly from the high 500,000s in early years to over one million THB in DP, with an annual fee average around 818,000 THB cited by independent fee aggregators.

• International School Bangkok (ISB) (Pak Kret, Nonthaburi). One of the oldest international schools in Thailand, authorized for the IB Diploma. Sits firmly in the premium tier on published fees. Note that ISB also offers an American high school diploma pathway alongside the IB DP; not every senior student is enrolled in the DP.

• Bangkok Patana School (Bang Na). British curriculum through Year 11 with the IB DP offered in Years 12 and 13. Published premium-tier fees of roughly 900,000 THB and above for the senior years. Patana is one of Bangkok's largest international schools by enrollment.

Tier 2 examples: mid-tier IB schools

Schools whose published DP-year tuition typically sits between roughly 600,000 and 900,000 THB. Many of these run two or three IB programmes, often with a British or hybrid pathway in earlier years that converges on the IB DP in Years 12 and 13. Cohort sizes and campus scale vary considerably within this tier.

• KIS International School (Huai Khwang). The only Bangkok school currently authorized across all four IB programmes (PYP, MYP, DP, and CP). Published fees place it in the mid-tier band, with the DP year toward the upper end.

• Concordian International School (Bang Kaeo, eastern Bangkok). Full IB continuum (PYP, MYP, DP) with a published trilingual programme (English, Thai, Mandarin). Mid-tier published fees.

• St Andrews International School Bangkok (Sukhumvit, Sathorn, Sukhumvit 107). British curriculum with the IB Diploma offered in the senior years on the main Sukhumvit campus. Mid-tier fees, with the DP years sitting in the upper band of the tier.

• Ruamrudee International School (Min Buri, eastern Bangkok). American curriculum and IB DP pathway in the senior years. Mid-tier published fees.

Tier 3 examples: entry-tier IB schools

Schools whose published DP-year tuition typically sits between roughly 400,000 and 600,000 THB. These are often smaller schools, schools with shorter IB authorization history, or schools running only one or two of the IB programmes (commonly the DP alone, or PYP and MYP with the DP in candidate phase). Authorisation status here changes more often than in the higher tiers, so confirm the current programme list with both the school and the IB Organization directory before applying.

• Ascot International School (Ramkhamhaeng, Saphan Sung). IB-authorized for PYP and DP, with MYP listed as in candidacy at the time of writing. Around 500 pupils and a comparatively compact campus. Published fees place it in the entry tier.

• Pan-Asia International School (Ramkhamhaeng). Authorized for the MYP and DP, with primary years on a separate international curriculum. Entry-tier published fees.

• Wells International School (multiple campuses, including On Nut and Bang Na). The On Nut campus offers the IB Diploma in the senior years; the Bang Na campus runs PYP only at the time of writing. Entry-tier published fees on both campuses.

The fee categories most parents underestimate

Tuition is the headline number. It is also rarely the full annual cost. The categories below routinely add a meaningful percentage on top. We have seen all-in costs that exceed the headline tuition by 20 to 35 percent for first-year families, and the gap is often larger in DP years because of exam fees.

• Application fee: paid once at the point of applying, typically not refundable. Range varies but is rarely insignificant.

• Registration fee or enrollment deposit: paid once a place is offered. Some schools count this against first-year tuition; others do not. Ask explicitly.

• Capital or development levy: an annual or one-off fee that funds school building works. Premium-tier IB schools in Bangkok often charge a substantial capital levy. This is the line item most parents miss when comparing schools.

• Exam fees: in DP years, the IB charges per-subject registration fees, plus the school may add an administration fee. Across six subjects, this can run to several tens of thousands of baht per student in DP Year 2.

• Uniform and PE kit: a real cost in the first year and at any growth spurt afterwards.

• School bus: where applicable, priced by route distance and whether the route is daily round-trip. A long route can cost as much as a small additional fee category.

• Lunch: included by some schools, charged separately by others. Ask whether the published tuition is fully inclusive of catering.

• Extracurricular activities (ECAs) and clubs: many free, some chargeable (e.g., specialist sports coaching, instrumental music tuition).

• Trips: residential and overseas trips become increasingly common from MYP onwards, and DP-related trips (sports tours, subject field trips, the CAS project trip) can be sizeable.

• Technology: device requirements vary; some schools provide laptops within tuition, others require families to provide a specified device.

• Learning support: where additional needs require in-school specialist support, schools sometimes charge a supplementary fee. We cover this in Section 11.

A worked example: the gap between headline and all-in

Consider a hypothetical Tier 2 IB school with headline DP tuition of 800,000 THB per year. A realistic all-in cost in DP Year 2, for a student who also takes a school bus and participates in two trips, might add up as follows.

The headline-to-actual gap is roughly 28 to 57 percent in this hypothetical case. Different families will hit different points within these ranges. Lower-tier schools tend to have proportionally smaller gaps; premium-tier schools sometimes have larger ones because their additional fee categories scale up too.

Sibling discounts, scholarships, and fee inflation

Sibling discounts: many Bangkok IB schools offer reductions for second and subsequent children enrolled simultaneously, typically on a sliding percentage. The structure varies. Some schools discount only the second child; others apply progressive reductions across all siblings. Discounts are usually applied to tuition only, not capital or other fees.

Scholarships: most established IB schools offer some form of scholarship at sixth-form age, awarded on academic merit or specific talents (music, sport, arts). They are competitive, often with a small number of full-fee or partial-fee places per year. Application timelines run separately from the main admissions cycle. If scholarships matter to your situation, ask each school for its current scholarship list, including the number of awards made in the most recent year and the application deadlines.

Year-over-year fee inflation: Bangkok international school fees have generally tracked above general inflation for the past several years. Asking each school for its tuition published for the past three years is a fast way to see the trajectory; a school that has raised fees 8 percent annually for three years is a different financial proposition from one that has raised fees 4 percent annually.

Admissions

If you have just hit the admissions stage, this is usually the point where parents tell us they feel most overwhelmed. Multiple deadlines, multiple assessments, multiple application portals, all running in parallel, and most of the people you ask for advice are in slightly different situations than yours. This section walks the process in order, with notes on the things schools rarely volunteer until you ask.

When to apply

The Bangkok international school year typically starts in mid-August and runs to mid-June, although a small number of schools follow alternative calendars. The peak entry years for IB schools are: PYP entry at age 3 or 4 (most over-subscribed at the most established schools), MYP entry at age 11, and DP entry at age 16 (for families switching curriculum specifically for sixth form).

Lead times vary by tier. Tier 1 schools at popular entry points often need applications submitted 12 to 18 months in advance, with assessment and offer cycles running on internal calendars. Tier 2 and Tier 3 schools generally have shorter lead times, sometimes admitting at any point in the year if space allows. For mid-year arrivals, schools running formal admissions calendars may make exceptions, but availability narrows quickly. The honest version: if you are arriving in Bangkok mid-academic-year and want a Tier 1 IB school, expect the available shortlist to be smaller than it would be if you applied for the August intake.

The application process, step by step

1. Initial enquiry: contact admissions, request the current fee schedule and admissions calendar. This is the conversation where you ask whether the school has any availability at your child's year group.

2. Submit application form and supporting documents (see below). Pay the application fee.

3. School assesses the application. May request additional information or interviews with parents.

4. Assessment: the child sits the school's age-appropriate admissions assessment. We cover formats below.

5. Offer or waitlist decision communicated, typically within a few weeks of assessment.

6. If offered: pay registration deposit to secure the place. If waitlisted: ask explicitly how the waitlist works and where your child sits on it.

7. Visa and documentation processing for non-Thai students. This runs in parallel with the school's onboarding paperwork.

8. Uniform fitting, transport setup, first-day orientation typically scheduled in the weeks before term begins.

What entrance assessments involve, by age

PYP entry at age 3 to 5: usually a play-based observation session, where the child interacts with admissions staff in a structured but informal setting. Some schools include a parent interview. Schools are looking for readiness markers (basic communication, social interaction, attention) rather than academic skills.

PYP entry at age 6 to 11: a written assessment in English and mathematics at age-appropriate level, sometimes with a short reading component. Some schools also assess in the host language if the child has prior exposure. Schools are looking for whether the child can follow the existing class without disproportionate intervention.

MYP entry at age 11 to 15: written assessments in English (reading comprehension, writing), mathematics, and sometimes a science or general reasoning component. Schools are looking for academic level and English fluency for an MYP-paced classroom.

DP entry at age 16: a more formal assessment process, often including English (sometimes a writing piece), mathematics at the level corresponding to the candidate's intended DP Maths choice, and an interview that probes subject choice rationale, motivation, and self-management. The assessment is doing two things: confirming academic readiness and confirming fit with the specific subjects the school can offer.

Required documents

• Recent school reports (typically the last two academic years, sometimes more).

• Recent reference or recommendation from current school (often a confidential teacher or head reference).

• Birth certificate or equivalent ID for the child.

• Passport copies for the child and parents.

• Vaccination records and medical history.

• English language evidence if the child is not from an English-medium school (test results or sample work).

• Special educational needs documentation, where applicable, for transparent placement; we cover SEN questions in more detail later in this guide.

Does the child need to speak English fluently?

For PYP entry at younger ages, no. Most Bangkok IB schools have EAL (English as an Additional Language) provision built into the early years and can accommodate children with limited or no English on entry, although the level of support varies. For MYP entry, the bar rises. The MYP is academically demanding in English, and most schools require enough English for the child to follow lessons with EAL support, not from scratch. For DP entry, English fluency is almost always required, because the DP workload is too heavy to layer English acquisition on top. Concrete questions to ask the school: how many EAL specialists does the school employ; what is the maximum EAL caseload per specialist; what is the school's policy on EAL exit (when does formal support stop); are EAL students grouped together in any subjects, and if so, which?

Waiting lists

Most established IB schools maintain waiting lists at over-subscribed year groups. The honest version: waiting list movement is unpredictable. Some lists move steadily as families relocate; others sit static for a year. When you are placed on a list, ask three questions explicitly: where on the list is my child currently, how often does this list move historically, and what is the typical notice period when a place opens up. If the school cannot answer these, treat the waiting list as low-probability and continue applying elsewhere.

Nationality caps

Some Bangkok international schools historically have applied informal or formal limits on the proportion of any one nationality in a year group, to maintain the international mix. This is not universal. Where it does apply, it most often affects the largest expat communities in Bangkok at any given time. If your nationality is heavily represented at a particular school, ask whether nationality balance is a factor in admissions decisions for your child's year group. Schools that operate caps are usually willing to confirm it; schools that do not have caps will typically say so directly.

Academic outcomes and university destinations

We are deliberately careful here. Bangkok IB schools each publish their own results in their own format, and parents understandably want a school-by-school comparison table. Comparing pass rates and average points across schools without standardizing for cohort selectivity, EAL support density, and how schools handle weaker candidates produces league tables that are misleading more often than they are helpful. Instead, we suggest three concrete data points to look for when you visit each school.

Three numbers worth asking for

1. Average DP point total in the most recent graduating cohort, with the cohort size disclosed. A 38-point average from a cohort of 45 students is a different signal from a 38-point average from a cohort of 8 students. The IB worldwide average sits in the low 30s; a Bangkok school posting averages in the high 30s or above is showing strong cohort outcomes.

2. Diploma pass rate (the percentage of students who completed the full Diploma successfully, not just took DP courses). A pass rate well above the IB worldwide average (typically in the 70s to low 80s percent globally) is a strong signal.

3. The full distribution of grades, ideally by subject, not just the headline averages. Schools with consistent results across subjects (no one weak link) tend to indicate steady teaching depth across the faculty.

Typical university destinations

IB Diploma graduates from Bangkok schools typically distribute across the UK, US, Australia, continental Europe, Asia (Singapore, Hong Kong, Japan, China), and Thailand's English-medium and international programmes. The exact distribution varies hugely by school and by year. Some Bangkok IB schools send a clear majority to the UK; others to the US; others have a more even spread. The destination pattern is shaped by the school's parent demographics as much as by the curriculum itself, because most graduating students apply to the universities their families know best.

UK university entry from the IB Diploma

UCAS publishes a tariff conversion that translates IB points into the same scale used for A-Levels. Russell Group universities typically ask for IB totals in the high 30s to low 40s, with specific HL grade requirements (often 6 or 7 in HL subjects relevant to the course). Oxford, Cambridge, and Imperial typically ask for the high end of the 38 to 42 point range with specific HL subject grades. Universities of all tiers across the UK accept the Diploma; it is one of the two most familiar non-British qualifications in UK admissions.

US university entry from the IB Diploma

US universities use a holistic admissions process. The IB Diploma is well regarded and frequently signals academic rigour to admissions readers. Many US universities award college credit (advanced standing) for HL subject grades of 5 or above, which can shorten time-to-degree or open up advanced course slots in freshman year. The IB Diploma does not replace the SAT or ACT requirement at universities that still require standardized tests, although the number of US universities going test-optional has grown significantly in recent years. Confirm current policies for any specific university.

Australian university entry from the IB Diploma

Each Australian state publishes a conversion table from IB points to the ATAR (Australian Tertiary Admission Rank). The conversion treats high IB scores as comparable to high ATAR ranks. Major Australian universities accept the Diploma directly and treat it as equivalent to the local senior secondary qualification for entry purposes.

Asian university entry from the IB Diploma

Singapore (NUS, NTU, SMU), Hong Kong (HKU, CUHK, HKUST), Japan (established private universities such as Waseda and Keio's English-medium programmes, plus increasingly the national universities' English-medium tracks), and China (the major universities' English-medium tracks, plus international programmes) all accept the IB Diploma. Entry requirements vary widely by course and university; the most competitive courses typically ask for the high 30s in IB points with specific HL subject grades.

Thai university entry pathways

Thailand's largest universities (Chulalongkorn, Mahidol, Thammasat, Chiang Mai) offer two parallel tracks for sixth-form leavers: international or English-medium programmes (often labelled "International Programme" or BBA-Inter, BMIC, etc.), and Thai-medium programmes. The international programmes typically accept the IB Diploma directly, with specific point and subject requirements published per programme. Thai-medium programmes generally require Thai-language qualifications regardless of secondary curriculum, which can make them a less natural pathway for IB graduates whose Thai is at conversational rather than academic level. We cover Thai-medium pathway logistics in more depth in the Relocation Playbook.

Workload, honestly compared

The version most current Bangkok DP students would tell you over coffee: the Diploma is heavy. Most students report 2 to 4 hours of homework per weeknight in DP Year 1, building higher in DP Year 2 around the Extended Essay deadline and exam preparation. CAS adds engagement time outside academic homework. TOK adds reading and reflection that bleeds into evenings and weekends. Sixth-form A-Level students with three subjects often report comparable or slightly lower nightly workloads but with higher concentration in the final exam term. American AP students with 3 to 5 APs report variable loads depending on subject choice. The honest takeaway: the IB is not the heaviest possible sixth-form programme on a per-night basis, but its breadth means there are fewer evenings without something due in some subject.

Daily life

What it actually feels like to be a student or parent at a Bangkok IB school, beyond the marketing photos. Most of these features are well understood by the time families are visiting schools.

Class sizes

Bangkok IB schools typically publish class size targets between 18 and 24 students at primary and secondary level. DP class sizes are often smaller, particularly for less popular subjects, where a Higher Level group might run with 6 to 12 students. Some schools cap classes lower than 20; a few run them higher. Ask for the actual average class size in your child's year group, not just the published target.

Teaching staff

School marketing language about "qualified" or "experienced" teachers can mean different things in practice. The version we wish someone had given us: ask each school what proportion of its teaching staff has IB-specific training (the IB runs its own teacher certification programme), how long the average teacher has been at the school, and what the staff turnover has been over the last three years. A school where most teachers have been there for five years and have IB training is a different teaching environment from one with high annual turnover, regardless of the marketing copy. Native English-speaking teachers are common in Bangkok IB schools but the proportion varies; ask explicitly if it matters to you.

School calendar and hours

Most Bangkok IB schools run mid-August to mid-June, with three terms separated by a winter break (December to early January) and a spring break (often around the Thai Songkran holiday in April). The school day typically begins between 7:45 and 8:30 and ends between 14:30 and 16:00, with extracurricular activities running afterwards. DP students usually have study periods built into their timetable that other year groups do not.

Uniforms

Most Bangkok IB schools require uniforms for all year groups up to the end of MYP, and some schools require them through DP as well, while others move to a "sixth form dress code" rather than a formal uniform for DP students.

Extracurricular activities

ECAs are central to most IB schools, partly because they feed into CAS for DP students and into the MYP service learning expectations. Range varies by school size and facilities. Larger Bangkok IB schools typically offer dozens of ECAs across sports, arts, academic clubs, and service groups; smaller schools offer narrower ranges. Sports, music, drama, and Model UN are common across most schools. Ask which ECAs run regularly (with a coach or coordinator) versus which are listed on the website but only run intermittently.

Pastoral structure

IB schools typically organize pastoral care through homeroom or form tutor systems in younger years, transitioning to year heads and deputy heads of school as students progress. DP students usually have a designated DP coordinator (often a senior teacher) who handles their academic progress alongside subject teachers, and a separate counselor or college adviser for university applications. Counsellor caseloads vary widely; ask how many students each university counsellor handles, because in DP the difference between 60 students per counsellor and 120 is felt directly in the quality of university application support.

Local language teaching

Thai is taught in some form at most Bangkok IB schools, but the depth varies considerably. Some schools offer Thai across all year groups as a meaningful second language with academic continuity; some offer Thai as a beginner option with limited progression; some offer it only in early years and replace it with other languages in MYP and DP. We cover the language picture in detail in the Language Question content series; for this section, the practical question is whether your child's potential second language pathway in MYP and DP is supported by the school's existing language tracks. Thai is a Group 2 language in the Diploma, available at some schools at SL or HL, but not at every Bangkok IB school.

Moving in, moving on

Most expat families do not decide once and stay put. The Bangkok IB intake includes families who have just arrived from Singapore, Hong Kong, the Middle East, Europe, the Americas, and other parts of Asia, and whose previous schools ran every conceivable curriculum. The IB's portability is genuinely one of its strengths, but transitions still take work. This section covers the most common moves we hear about.

From an IB school in another country to a Bangkok IB school

This is the smoothest transition. The PYP, MYP, and DP are designed to be portable across IB World Schools globally, so course content, assessment frameworks, and learner profile language all carry across. What does not always carry: specific subject options. A student moving mid-MYP from a school that offered, say, Mandarin Language Acquisition to a Bangkok school that does not, will need to switch language pathway. A student moving mid-DP after subject selections have been made cannot easily switch unless the receiving school happens to teach the same six subjects in the same HL/SL configuration. Time the move at year-group transitions wherever possible.

From another curriculum into the IB

Moving from a British curriculum into MYP at the equivalent year group is usually workable, although the inquiry-led teaching style and criterion-based assessment can take a term to adjust to. Moving from an American curriculum into MYP is also workable, with the main adjustment being the IB's formal subject group structure compared to the more flexible American course catalogue. Moving from any curriculum into DP after Year 12 has begun is structurally very hard, as the IB front-loads internal assessments from the start. The realistic option for mid-Year 12 movers is to switch to A-Levels or to repeat DP Year 1 at the new school. Schools handle this case by case.

From Bangkok IB to another country

If the destination country has IB World Schools, a transfer is usually straightforward. The IB's central role here is genuine: an MYP transcript or a DP grade record is recognized across the IB network without translation. If the destination country does not have IB schools nearby, the move is more like any curriculum-to-curriculum transition. Mid-DP moves are the hardest case; a family moving in DP Year 1 should ask whether the destination school can match the student's existing subject choices.

Returning to the home country for university

The summary version: the IB Diploma is recognized in essentially every country a Bangkok expat family is likely to come from, with the practical caveat that some specific national systems (notably France for grandes écoles entry, or Germany for some Numerus Clausus subjects) have their own conversion rules and may require additional documentation. If your child is likely to apply for university in a country with non-standard entry rules, check the conversion process well before DP Year 2 begins.

Moving between IB schools within Bangkok

More common than parents expect. Reasons we hear: a sibling started in a different school and the family wants to consolidate; the original school's authorization does not run end to end (PYP only, no MYP) and the family is now reaching the transition point; the original school changed character through expansion or leadership turnover; commute times became unsustainable. Within Bangkok, moves between IB schools are generally easier than moves into IB from a non-IB school, because the curriculum carries.

Will it suit my child?

Curriculum fit is partly about academic style, partly about workload tolerance, and partly about temperament. We work through the angles parents most often ask about.

Is the IB too rigid?

The IB has structural rigidity that other curricula do not: forced breadth across six subject groups, mandatory core components, fixed pacing of internal assessments. For students who like to specialize hard and fast, this rigidity is the chief complaint. For students who do not yet know where they are heading, the rigidity is what keeps options open. There is no neutral answer. The honest version: if your child has already declared a strong direction (e.g., wants to study medicine and is sciences-focused), A-Levels are usually a more efficient path. If your child is still exploring, the IB's rigidity is doing useful work.

Suitability for creative children

The IB has explicit space for creativity in the curriculum: Group 6 is dedicated to the Arts (Visual Arts, Music, Theatre, Film, Dance), and CAS deliberately requires creative engagement outside academic subjects. Schools that take Group 6 seriously, with experienced specialist teachers and proper studio or rehearsal facilities, can suit creative children well. Schools that offer Group 6 nominally but resource it lightly are a different story. Visit the studios. Ask about the most recent IB Visual Arts grades. Ask how many students chose Group 6 last year.

Special educational needs (SEN) provision

IB schools in Bangkok vary considerably in their SEN provision. The IB itself has formal access arrangements policies for examinations, and most authorized schools can implement reasonable adjustments for diagnosed needs (extra time, scribes, separate rooms, modified format). Where schools differ is the depth of in-school specialist support: whether there is a dedicated SENCo (Special Educational Needs Coordinator), how many specialist teachers are on staff, what range of needs the school is set up to support, and whether any specialist support is included in tuition or charged separately.

Concrete questions to ask: Does the school have a SENCo on staff? How many specialist teachers does the SEN team have? What range of diagnoses has the school supported in the past three years? What is the school's policy on additional charges for SEN support? Does the school offer in-house educational psychology assessment, or refer out? What is the largest cohort of students with EHCP-equivalent needs the school has carried at any one time?

EAL provision

In day-to-day terms: most established Bangkok IB schools have EAL programmes, but the structure varies. Some schools pull EAL students from specific lessons for targeted support; others integrate EAL specialists into mainstream classrooms; others offer afterschool or pre-school EAL sessions. Larger schools tend to have more granular EAL structures (multiple proficiency tiers, dedicated EAL coordinator); smaller schools may offer a single EAL track. Ask each school how its EAL programme is structured and what the typical exit timeline looks like (how long from initial placement before students typically move out of formal EAL support).

Gifted and talented programmes

Bangkok IB schools typically do not run formal gifted-and-talented streams in the way some national-system schools do. The IB framework itself is built around personalized challenge through extension activities, differentiated tasks, and (in DP) Higher Level subject choices. Some schools run additional enrichment programmes, competitions, or accelerated tracks for specific subjects. If gifted provision matters to you, ask each school how it identifies and challenges high-achieving students, and what specific programmes (e.g., maths olympiad coaching, MUN, science fair preparation) are available at the relevant year group.

Age-of-entry: is it too late at age X?

Age 3 to 6 (PYP early years): no concerns. The PYP is designed for arrivals at any point. Age 7 to 11 (PYP mid to late): straightforward in most cases, with the inquiry-led approach taking a term or two for children from more direct-instruction backgrounds. Age 11 to 14 (early MYP): straightforward if academic level matches; the language acquisition group can be a hurdle for children who have not had a prior second language. Age 14 to 16 (late MYP): more challenging, because the Personal Project assumes some prior MYP grounding. Workable but the school will assess carefully. Age 16 (DP entry): is a clean entry point if the student has a strong general academic record and English fluency, but it is the highest-stakes entry into the IB system. After Year 12 has begun: very difficult.

Accreditation: how to tell a real IB school from a marketing one

This section is short but important. The IB Organization maintains a strict authorization process for any school using the IB name. Schools that use IB-related language without authorization are not unheard of, and the marketing language they use is often confusingly similar to that used by authorized schools. Knowing the difference takes about ten minutes if you know what to look for.

The accreditation that matters: IB authorization

A school is officially "IB-authorized" only when the IB Organization has assessed it against the IB Programme Standards and granted authorisation for one or more of the four programmes (PYP, MYP, DP, CP) individually. Authorization is per-programme, not per-school. A school can be PYP-authorized but not MYP- or DP-authorized, in which case it can teach the PYP under the IB name but not the other programmes. Authorization is renewed periodically through an evaluation process; a school in evaluation is still authorized, but a school whose authorization has lapsed is not.

How to verify authorization: the IB Organization maintains a public, searchable database of authorized IB World Schools at ibo.org. Searching the database returns each school's authorization status by programme and date. If a school is not listed, it is not authorized. If it is listed for one programme but not another, it is not authorized for the missing programme. Cross-check every Bangkok school's claims against this database directly.

Candidate schools

A "candidate school" is a school that has applied for IB authorization but has not yet completed the process. Candidate status means the school is implementing the framework with IB Organization guidance, but is not yet fully authorized and cannot yet award IB Programme outcomes (a candidate PYP school cannot run a fully recognized PYP Exhibition; a candidate DP school cannot register students for IB Diploma examinations). Some Bangkok schools sit in candidate phase legitimately; this is fine, but you need to know what it means before enrolling. A child who starts PYP at a candidate school may need to transfer if authorization is not granted on the planned timeline.

Other accreditations Bangkok IB schools commonly hold

In addition to IB authorization, many Bangkok international schools also hold accreditation from broader school accreditation bodies. The most common in Bangkok are: the Council of International Schools (CIS), which conducts periodic whole-school evaluations against international standards; the Western Association of Schools and Colleges (WASC), more common at schools with US curriculum heritage but also held by some IB schools; the New England Association of Schools and Colleges (NEASC), similar profile to WASC; and the Office for Standards in Education (Ofsted) in the UK or its inspection service equivalents, which inspects British-curriculum sister schools rather than IB content directly.

These broader accreditations do not certify the IB programmes themselves but do indicate that the school as a whole has been independently evaluated against published institutional standards. Schools holding multiple accreditations are not automatically better, but the presence of CIS or WASC alongside IB authorization is a useful signal of institutional discipline.

Thai Ministry of Education licensing

Every international school operating in Thailand is required to hold a license from the Thai Ministry of Education and to comply with its requirements (including a minimum number of Thai Studies hours per year, depending on student age and citizenship). MoE licensing is a baseline legal requirement, not a quality marker. A licensed school is a legally operating school; it is not, by virtue of licensing alone, a school you should prefer. Ask schools to confirm their MoE license number if it matters to your situation; reputable schools provide this on request.

Bangkok practicalities

The school decision is shaped by Bangkok's geography in ways that families relocating from elsewhere often underestimate.

Commute time as a school decision

The headline number we wish someone had given us: commute time, not commute distance, is the variable that matters. Bangkok traffic is unpredictable, and a 12-kilometer journey can take 25 minutes at one time of day and 90 minutes at another. School buses are typically routed through residential clusters and can extend any individual child's journey beyond what a private car would take. A one-hour-each-way commute over the school year adds up to roughly 360 hours, which is a real subtraction from family life. When you shortlist schools, model the commute realistically (not just the off-peak Google Maps estimate) before you fall in love with a particular campus.

BTS and MRT proximity

Some Bangkok IB schools sit within walking distance of a BTS or MRT station, which transforms the commute equation for older students. DP students at a BTS-adjacent school can travel independently from much wider catchments than children at a school requiring private car drop-off. Ask each school for its closest mass-transit access point and the actual walking distance, including the experience of crossing major roads near the campus.

School bus networks

Most established Bangkok IB schools operate bus networks across major residential areas. Routes are typically published with pickup points, indicative timings, and termly costs. The honest version: bus availability for your specific neighborhood is one of the most important practical questions a relocating family can ask. A school that does not currently run a route to your future neighborhood may add one if there is enough demand, but "enough demand" is rarely confirmed before you commit. Ask each shortlisted school for current route maps and pickup points relative to your housing area.

Neighborhood-school clustering

Bangkok's international school landscape is partly clustered around specific neighborhoods. Sukhumvit (especially the eastern stretches: Phra Khanong, On Nut, Bang Chak, Bearing) hosts a concentration of international schools including several IB World Schools. Bang Na (further east, near the expressway towards the airport) hosts another cluster. Pathum Thani and the northern suburbs host schools serving families closer to the international airport approaches. Sathorn and the inner CBD areas host fewer large-campus schools but several smaller and specialist providers. Each cluster has its own commuter logic; the bkkschools.com comparison tool lets you filter schools by proximity to a specified Bangkok address.

Parent community variation

The character of Bangkok IB school parent communities varies. Some schools have a clear majority of families from one or two regions (e.g., heavy European representation, or heavy regional Asian representation); some are more evenly mixed. The proportion of Thai families enrolled in international programmes is rising at most schools, which changes the parent-community dynamic over time. None of this is a quality marker; it is a fit question. Ask each school for its current parent demographic mix if community alignment matters to your family.

Campus security

All Bangkok international schools operate with formal campus security, including controlled access, security personnel, and visitor protocols. Standards are broadly comparable across the established schools. If you have specific concerns (after-school pickup procedures, residential boarding, security around major events), raise them directly during the campus visit and ask for the school's published security policy.

What we don't cover, and what to do next

We have tried to give you the structural picture of the IB in Bangkok in one place. This guide is not, and will not become, several things.

• It is not a ranking. We will not publish a list of "best" Bangkok IB schools. We compare; you decide.

• It is not a review site. Parent opinions and individual school reviews are valuable but they are not what bkkschools.com produces. We publish verified, sourced data.

• It is not a relocation concierge. We do not handle visa applications, housing, or school-specific introductions.

• It is not a directory of every IB school. We focus on what helps families compare; the IB Organization's own database is the authoritative list of authorized schools.
