Ruamrudee International School (RIS)

Official website checked 2026-10-06: per-term fees published (2025-2026): Tuition per semester: Pre-K 243,000; KG 243,000; G1 330,000; G2-5 330,000; G6-8 348,000; G9-12 383,000 (2 semesters/yr). The school's own combined annual totals (tuition + campus development 10,000/yr + technology + lunch where applicable) are 538,400 / 544,400 / 718,400 / 686,000 / 716,000 / 786,000 for the same bands (2025-2026). Recorded annual figures retained. Official-site discrepancy noted 2026-10-06: Chunk boarding field says 'No (limited)', but RIS's own fee schedule publishes weekly and full-time boarding rates for its residence (shared rooms). Also, the recorded domain ris.ac.th could not be resolved from this environment; the school's current official domain per its own fee-document letterhead is rism.ac.th. Boarding fees (official site, 2026-10-06): Boarding, shared rooms (2025-2026, updated 6 Jan 2025): weekly 163,800/semester = 327,600/yr; full-time 242,500/semester = 485,000/yr; visa/re-entry permits 7,700/yr for non-Thai boarders. Sourcing note: RIS's official domains were unreachable from the checking environment; figures are from RIS's official 'Tuition & Fees 2025-2026' document (rism.ac.th letterhead) read via a mirror copy of that PDF.
