St. Andrews International School Sathorn

St. Andrews International School Sathorn opened in 2003 and is one of four St. Andrews schools in Thailand run by the Cognita group. The others are Sukhumvit 107, Dusit and Green Valley in Rayong. It has no connection to the Nord Anglia school called St Andrews International School Bangkok. The campus is a heritage building on Sathorn Soi 4 off North Sathorn Road in Bang Rak, within walking distance of Sala Daeng BTS and the Silom and Lumpini MRT stations. Many families live in the condominiums nearby.

This is a primary-only school for children aged 2 to 11. It runs from part-time Nursery through Kindergarten and Reception to Year 6, following the English National Curriculum with the Early Years Foundation Stage. Pupils come from more than 40 nationalities, and many start with little English, so additional language support is available. For secondary school, pupils usually move to St. Andrews Sukhumvit 107, which offers IGCSE and the IB Diploma. The school is accredited by Education Development Trust and ONESQA and is a member of ISAT.

Facilities include a library, an IT room, a cooking room, a music room, a performing arts hall, a multi-purpose sports hall, an outdoor hard court and access to a 25-metre pool. For 2026–27, full-day Nursery costs THB 571,000 a year, Reception THB 659,600 and Years 3 to 6 THB 735,500. There is a THB 5,000 application fee, a one-time enrolment fee of THB 120,000 (or a capital levy option) and a refundable THB 100,000 deposit.
