Not a tier decision — a curriculum and geography decision. ISE in Bowin runs American AERO + NGSS through IB Diploma on a campus whose current enrolment is not published inside Burapha Golf Club. TPIS in Nongprue runs British EYFS through dual-board A-Level on an ISP-managed Established campus. Both are full 2–18 day schools. Neither offers boarding. The question is which credential your child needs at 18 — and which commute your family can sustain daily.

ISE and TPIS both use their school-published 2026/27 fee PDFs. The table compares standard tuition before full-year-payment discounts; TPIS includes lunch, Primary/KS3 textbooks, insurance and standard stationery. American and British year groups do not map one-to-one.

Fee comparison is not apples-to-apples on inclusions: TPIS's published tuition includes lunch; ISE bills lunch separately. ISE is more expensive at early years (฿357,600 vs TPIS Nursery 2 at ฿273,000) but TPIS catches up by primary. At Sixth Form, ISE IB at ฿646,000 is ฿19,000 below TPIS Years 12–13 A-Level at ฿665,000, though the exit credentials differ. First-year cash outlay at ISE G11 is about ฿791,000 including the refundable deposit; TPIS Year 12 tuition plus application and enrolment is about ฿760,000.
ISE publishes an American AERO + NGSS route with an American high-school diploma or IB Diploma at Grades 11–12; TPIS publishes a British route through IGCSE to A-Level. The current sources cited on this page do not establish AP provision, a scheduled SAT, PSAT, MAP or TOEFL programme, a university-application platform service or transfer-credit arrangements at ISE. University entry requirements vary by institution and course, so ask both counselling teams to map the intended applications and provide current subjects, testing and support in writing.
ISE offers IB Diploma at Grades 11–12 (฿646,000/yr) — six subjects, Theory of Knowledge, Extended Essay and CAS. Students can also finish on the American high-school diploma without IB. TPIS runs A-Level via Cambridge or Edexcel boards. Compare the current subject combinations and the intended universities’ published requirements rather than assuming universal recognition or credit. ISE's IB band is ฿19,000/yr lower than TPIS's A-Level band, but these are different exit credentials.
TPIS is at 88 Moo 13, Pattanakarn Road, Nongprue, Banglamung; ISE is inside Burapha Golf Club at 282 Moo 5, Bowin, Sriracha. The addresses create different routes, but neither supports a universal minute estimate. Test both from the real home during school traffic and request current pickup, ride and late-activity timings.
ISE publishes a student-to-teacher ratio below 8:1, while current grade and graduating-cohort sizes are not published. TPIS publishes Ror Dor Cadet, Duke of Edinburgh and LAMDA programmes, but the cited sources do not establish current cohort sizes or participation depth at either school. Ask for the proposed class size, senior subject cohorts and activity participation instead of inferring daily experience from a ratio or programme list.
Thai-passport families considering TPIS's Ror Dor Army Cadet Programme should request current eligibility, attendance and completion requirements and verify any military-service consequence with the relevant Thai authority; the fee sources cited on this page do not establish a legal outcome. ISE publishes WASC accreditation and IBDP history, while TPIS joined ISP in 2025. Ask TPIS what ISP membership currently changes for this pupil rather than assuming a transfer or programme benefit.
You need boarding — see Rugby vs Regents. You want British in Nongprue at lower fees than TPIS — see MIS vs TPIS. You want another American-curriculum record or a different location — review the American schools hub and confirm each campus’s current operating grades and senior route in writing. For premium IB with boarding, see Regents.
Ask both admissions teams to price the same pupil for the same start year and payment basis. ISE publishes standard tuition of ฿357,600–฿646,000. TPIS publishes ฿273,000–฿665,000 from Nursery through Years 12–13. The endpoints cover different stages, so begin with the proposed class and keep any annual-payment discount on a separately labelled line.
At ISE, add application, non-refundable enrolment, refundable security deposit, lunch, bus, uniform, IB examinations and any assessed EAL charge. At TPIS, add its age-band application fee, one-time enrolment, transport, books for examination stages, uniforms, trips, examinations and any support charge; confirm which meals or services are included for the proposed class. Record every item as mandatory, optional, refundable, annual, termly or one-time.
ISE’s American pathway leads to its high-school diploma or IB Diploma. TPIS follows British progression through IGCSE to AS/A-Level using Cambridge International and Pearson Edexcel. Request the current subject list, prerequisites, timetable blocks, minimum cohort rules, counselling timetable and examination arrangements from each school. The relevant question is not simply IB versus A-Level, but whether the child’s intended subjects and prior study make that route usable.
For a pupil joining in secondary, ask admissions to identify any bridging work and courses that cannot be entered mid-cycle. For a younger pupil, observe how the present classroom prepares children for later assessment without allowing a distant credential to outweigh daily teaching and pastoral fit.
ISE publishes a student-to-teacher ratio below 8:1, not current class or graduating-cohort sizes. Ask for the actual proposed class, senior subject cohort and activity participation. At TPIS, ask the same questions rather than assuming its broader programme list is available at equal depth to every year group. Scale matters only through the opportunities and support this child can access.
Run Bowin and Nongprue journeys at school times, request exact bus quotes and record pickup duration and late-activity returns. The final offer should combine the class, complete invoice, qualification subjects, support and weekly commute. That makes the American/IB versus British/A-Level choice operational rather than theoretical.
Before paying, save a one-page decision record with the source date for every fee, the named admissions contact and every unresolved condition. Review it again before IGCSE, IB or A-Level choices begin. A school can remain a good fit while the child’s subjects, support needs or family location change; planned reviews prevent continuity from becoming an assumption.

Curriculum and location. ISE in Bowin, Sriracha runs American AERO and NGSS through IB Diploma (WASC since 1999, IBO since 2004). TPIS in Nongprue runs British EYFS through Cambridge and Edexcel A-Level. Both are Established-tier day schools with published 2026/27 fees.
TPIS is at 88 Moo 13, Pattanakarn Road in Nongprue; ISE is at 282 Moo 5 in Bowin, Sriracha. Which is faster depends on the family’s exact address, traffic and bus route, so test both during the school run.
ISE offers IB Diploma at Grades 11–12 (฿646,000/yr tuition). TPIS does not — it runs British A-Level at ฿665,000/yr. Within the current directory evidence, ISE combines an American AERO/NGSS route with IBDP; confirm the exact senior offer for the intended cohort.
ISE IB Diploma at ฿646,000/yr is ฿19,000 below TPIS Years 12–13 A-Level at ฿665,000/yr. But the credentials differ. At middle school, TPIS Grade 7 (฿574,000) is also below ISE Grades 6–8 (฿600,500).
ISE students can apply, but entry requirements vary by university and course. Compare ISE’s current IB Diploma subjects with TPIS’s current A-Level subjects, then check each intended course’s published requirements. Ask both schools for their current counselling and testing support in writing.
