Glory Singapore International School

Glory Singapore International School (GSIS) was founded in 2008 and teaches children from Nursery (about age 2) to Grade 12. Its main Sukhumvit campus is split between two sites on Wachirathamsatit sois off Sukhumvit 101/1, between Bang Na and Phra Khanong. The Soi 18 site takes Nursery to Primary 2 and the Soi 30 site takes Primary 3 to Grade 12. A third site, the Ramintra campus in Khlong Sam Wa in north-east Bangkok, offers Nursery, kindergarten and primary classes.

Primary teaching follows the Singapore curriculum, with its strong mathematics and science, blended with British practice. Secondary students follow Cambridge programmes, and the school is a registered Cambridge International School offering IGCSE, AS and A Levels. Classes are taught in English, with daily Chinese and Thai, so students learn three languages. GSIS is accredited by the UK-based Education Development Trust (one of the bodies approved by the Thai Ministry of Education for international-school inspection) and by ONESQA. It is an ISAT member school and a registered centre for Chinese proficiency (HSK) testing. Most families are Thai and Asian, and the school has a family-style, close-knit atmosphere.

The Soi 30 building houses the upper primary and secondary years and has a swimming pool and a covered sports area. The Ramintra campus has its own multi-storey building and library. Fees are among the more affordable for international schools in Bangkok. For 2026–2027, tuition per term is THB 67,000 for Nursery, THB 77,000 for Primary 1–3, THB 87,000 for Grades 7–9 and THB 92,000 for Grades 10–12. Textbooks and lunch are charged on top, at about THB 10,500–13,000 per term each. New students pay a THB 72,000 school development fee and a THB 5,000 application fee. Discounts apply for paying yearly and for siblings.
