St Stephen’s International School Bangkok is an established British curriculum school that has taught the city's international families since 1998, covering the early years through to the sixth form. Its programme runs the International Primary Curriculum into IGCSE and then offers both A Level and the IB Diploma at the senior end, and the school features among the international options on our Bangkok city hub. A sister campus near Khao Yai National Park adds a boarding option outside the capital.

At a glance
Curriculum and academics
St Stephen’s builds its lower school on the International Primary Curriculum within a British curriculum framework, moves into IGCSE in the upper secondary years and then gives sixth form students a choice between A Levels and the IB Diploma. Offering both senior routes under one roof is unusual in Bangkok and lets families pick the breadth of the IB or the focus of A Levels without changing school.
That dual pathway is the school's distinctive feature and shapes a broad, internationally minded sixth form. If you are still deciding between the two routes, our British curriculum guide sets out how A Levels work and where the IB Diploma differs.

St Stephen’s International School fees
St Stephen’s sits in the mid band on our Bangkok international school fees guide, more accessible than the city's premium flagships while still offering recognised IGCSE, A Level and IB qualifications. Tuition rises with each stage and is highest in the sixth form, so treat any single figure as indicative and confirm the current schedule with admissions, and note that the Khao Yai campus carries separate boarding charges.
Budget for the usual Bangkok extras alongside tuition: a registration fee, a deposit, uniform, examination entry in the IGCSE, A Level and IB years and an optional bus service. Our fee calculator helps turn the headline tuition into a realistic annual total once those line items are added.
Admissions
The academic year starts in August, so the main application window runs through the preceding autumn and winter, with some through year entry where space allows. Assessment is age appropriate and draws on previous reports, with English and subject readiness checked for older applicants and a discussion of A Level or IB subject choices for sixth form entrants.
Boarding at the Khao Yai campus follows its own process and timelines, so families considering that option should enquire separately. The practical first steps for the Bangkok campus are to register interest, share recent reports and arrange a tour.
Location and who goes there
The Bangkok campus sits in the Viphavadi Rangsit corridor in the north of the city, with road and expressway links rather than a single rail station as its main access, so commute planning matters when families weigh it against more central options. The sister campus near Khao Yai National Park, around a hundred and fifty kilometres away, offers a rural boarding setting that suits families wanting their children outside the capital.
The community is international with a strong British and wider expatriate core, reflecting the curriculum and the dual senior pathway. For how the northern districts compare with central and riverside Bangkok, and the schools near each, return to the Bangkok city hub.
