School closed2026-10-06 · Josuikan Bangkok International School — 31 March 2024

Correction2026-10-06 · Modern International School Bangkok (MISB) — Official website checked 2026-10-06: no published fee schedule. Correction 2026-10-06: website corrected from mis.ac.th — which belongs to Mooltripakdee International School (Pattaya) — to the school's own site, misb.ac.th (Sukhumvit 39, Bangkok; established 1997).

School closed2026-10-06 · New Sathorn International School (NSIS) — 2022

School closed2026-10-06 · VERSO International School — July 2026

Correction2026-10-06 · Udon Thani International School (UDIS) — Official website checked 2026-10-06: full per-grade table published for 2025/2026; figures now from official site. Official-site discrepancy noted 2026-10-06: Chunk 2026/27 range 198,172-428,480 is a TOTAL including catering+materials; the official tuition-only table (2025/26) is 190,550-412,000 with catering/materials billed on top - same order of magnitude, different basis. Site now states UDIS is authorised for PYP, MYP AND DP and CIS-accredited (chunk said MYP candidate only) - curriculum/accreditation have advanced. Enrolment as stated on official site (2026-10-06): 150+ students (school's own site text); current homepage also states 29 student nationalities. Coordinator correction 2026-10-06: the 198,172-428,480 range is the school's current official TUITION-ONLY schedule for 2026/27 — every band is exactly +4% on the 2025/26 tuition table, and catering (22,167-30,480) and materials (9,466-32,782) appear as separate tables on the same page. The earlier same-day reading that described it as an all-in total was an inference from the old dataset label and is withdrawn; the 2025/26 tuition-only range 190,550-412,000 is superseded.
