Wells International School

Wells International School operates two main Bangkok campuses: one near Sukhumvit 36 in the Thong Lo–Phrom Phong area, and one on Sukhumvit 105 (On Nut).

The school offers American High School Diploma and IB programs alongside Thai curriculum support. The On Nut campus handles younger year groups and the Sukhumvit campus serves older students, though the split varies — confirm the current structure when visiting.

Fees are somewhat lower than the most expensive international schools in Bangkok while still offering a recognized international curriculum, which can make Wells a practical option for families balancing quality and cost.

Both campuses have good BTS access: the Sukhumvit campus is near Thong Lo BTS and the On Nut campus is near On Nut BTS.

Visit both campuses if relevant to your children’s year groups, review the current fee schedule, and confirm the curriculum pathway for each grade before enrolling.
