St Andrews Sathorn is a primary school that has earned consecutive Gold ratings from the Education Development Trust for outstanding British curriculum delivery, and the setting matches the reputation.
A beautiful heritage building on Sathorn Soi 4, close to Silom Road and within easy reach of Chong Nonsi BTS, with a 25-metre pool, performing arts halls, music rooms, and a kitchen classroom. It serves children from age 2 to 11 (Nursery through Year 6) and is part of the Cognita global network. Around 40-plus nationalities, with a genuinely international community and a close-knit, family atmosphere that families consistently describe as the school's defining quality.
The English National Curriculum is delivered with strong emphasis on individual learning and academic foundations. This is a primary-only school: there is no continuation beyond Year 6, and the natural onward pathway for most families is St Andrews Sukhumvit 107 for secondary, which provides a seamless British curriculum continuation.
Fees run from roughly 577,500 THB annually at Nursery level, with a one-time Entrance Fee of 120,000 THB or a Capital Levy option for shorter-term families. For families in Sathorn, Silom, Riverside, or the CBD corridor, this is one of the most centrally located and consistently well-regarded British primary schools in Bangkok.

What You Should Actually Know About St. Andrews Sathorn
St. Andrews International School Sathorn is a small, community-oriented British international primary school located in Bangkok's central business district, a short walk from Silom Road. Established in 2003 and part of the Cognita group, the school caters exclusively to children aged 2 to 11, covering Nursery through Year 6.
That primary-only focus shapes everything: classrooms, specialist spaces, and daily rhythms are calibrated for younger learners, not stretched to accommodate teenagers. The school follows the English National Curriculum, supported by an inquiry approach in which children learn through hands-on projects, active exploration, and collaborative tasks rather than rote instruction.
Class sizes are capped at 20 for Reception through Year 6, and at 15 to 18 for Nursery and Kindergarten, with each class staffed by a qualified teacher and a teaching assistant. Around 90 to 95% of teaching staff are from the UK, all holding appropriate qualifications. This concentration of British-trained teachers is notably consistent by Bangkok standards.
The school community draws from over 42 nationalities, with Thai students making up approximately 30 to 36% of the roll. Top represented international nationalities include American, Australian, French, British, and Indian families.
Situated on Sathorn Soi 4, a five-minute walk from BTS Saladaeng and close to MRT Silom and Lumpini, the campus occupies a heritage building with a 25-metre swimming pool, an air-conditioned canteen, two halls used for performing arts and indoor PE, an IT suite, a cooking room, a dedicated music room with practice rooms, a library, and a hard court for outdoor sports. The school uses GL Assessments benchmarked against UK standards: in the 2024-25 academic year, 93% of graduating Year 6 students reached or exceeded expected levels in English, 96% in Maths, and 92% in Science.
Parents receive regular updates on their child's learning via the Seesaw platform. Families considering St. Andrews Sathorn should weigh its strengths against its practical realities. The school's campus, while well-equipped for its age range, is smaller than many Bangkok international schools with secondary sections. Secondary schooling beyond Year 6 is not offered on site; instead, the school has a formal articulation agreement with St. Andrews Sukhumvit 107 (S107), with guaranteed placement and no additional enrolment fee for Sathorn graduates.
The school operates on a 3-term billing structure and holds EDT Gold accreditation, the highest standard issued by the Education Development Trust. It is best suited to families with children aged 2 to 11 who value a close-knit British primary community, walking distance from central Sathorn-Silom residences, and a clear, structured pathway into secondary education through the wider St. Andrews network.
