Astra Academy opened in 2021 as the newest school in the Kids' Academy family, a group with 18 years of experience in early years and primary education in Bangkok.
It is a British curriculum school from Year 1 through Year 13, following the English National Curriculum through to Cambridge IGCSE and A-Levels, with a total enrolment capped at around 500 students. That cap is part of the point: small class sizes, personalised support, and a community feel are the design principles, not afterthoughts.
The location is one of the most practical of any secondary-age school in central Bangkok: Ekkamai 14 Alley in Khlong Tan Nuea, Watthana, a short ride from Ekkamai BTS and well placed for families in the Thong Lo, Ekkamai, and Phrom Phong corridor.
Fees run from 504,000 to 537,000 THB annually, placing this well below the premium British schools in the same area and making it one of the more accessible Cambridge pathway options in central Sukhumvit.
The school is still building toward full capacity at senior level, which means smaller cohorts in the upper years for now. For families who want a British curriculum with Cambridge IGCSE and A-Levels, small classes, a central Ekkamai location, and fees that leave room in the family budget, Astra Academy is worth a visit.

Key Facts
Astra Academy International School: What You Should Know About It
Astra Academy International School is the secondary-level extension of the long-running Kids' Academy preschool group, opened in October 2021 in the building that once housed SISB at the deep end of Ekkamai Soi 14. It runs the English National Curriculum from Year 1 to Year 11, with Cambridge IGCSE as the current exit qualification and a Sixth Form (Cambridge A-Levels) targeted for a 2027 launch rather than already operating.
Director of Community Jack Ruenprapan told TIS Monitor in 2021 that "the maximum limit is set at 500 students", and BKK Kids' current listing puts the community at "over 55% international students representing more than 30 nationalities", with families drawn heavily from the Japanese and Western expatriate population along the Thong Lo-Ekkamai corridor.
The student experience is built around a weekly timetabled Wellbeing lesson for every year group, a Mandarin lesson per week in Primary, and a culinary classroom embedded in the Design Technology curriculum.
Architecturally the campus is dominated by the "Astra Absorbatory", a sculptural centrepiece, and the school's own about page claims Astra is "the first international school in Thailand to achieve Eco School Status under the Ministry of Natural Resources and Environment".
The trade-offs are honest. Astra deliberately built scaled facilities, a small pool for younger children, a smaller-than-regulation football pitch, a covered sports area, and partners with external clubs for the rest, in order to hold tuition well below nearby Bangkok Prep, KIS and St Andrews 71.
For families who want a calm, neighbourhood-scaled British school with native English teachers and an explicit talent-development matrix, the proposition is clear. For families who need a Sixth Form starting now, on-site Olympic-grade sports, or a published IGCSE results record, Astra is not yet that school. Best for Thong Lo and Ekkamai families with Primary or lower Secondary children who want British education at sensible pricing in a small, design-led setting.
