ISE tuition from ise.ac.th 2026/27 schedule (tuition only — lunch, bus, uniform, and IB exam fees separate). Rugby from its rendered school-published 2026/27 fee schedule. American and British year groups do not map one-to-one at every stage.

Fee comparison is symmetric in precision: both publish exact year-by-year tuition. ISE is lower at Sixth Form (฿646K tuition only vs Rugby ฿999K A-Level) — ฿353K/yr gap. One-time fees diverge sharply: Rugby ฿200K acceptance plus a ฿100K refundable student deposit vs ISE ฿90K enrolment plus a ฿50K refundable deposit. ISE tuition excludes lunch, bus, uniform, and IB exam fees. Rugby Y1 entry cash outlay ≈ ฿1,041,500 vs ISE Pre-K all-in lower at entry but still premium. Only Rugby offers boarding (from Year 6). The curriculum fork is wider than the fee fork — American AERO/NGSS + optional IB Diploma vs British A-Level only on Rugby's published 80-acre campus.
ISE publishes an American AERO + NGSS route with an American high-school diploma or IB Diploma at Grades 11–12; Rugby publishes a British route through IGCSE to A-Level. The current sources cited on this page do not establish AP provision, a scheduled SAT programme, a university-application platform service, transfer credit or universal US/UK admissions outcomes. Families should give both counselling teams the intended institutions and courses, request the current subjects and testing support in writing, and check each university’s current entry, English-language and credit policies.
Rugby is A-Levels only at Sixth Form — the focused, specialise-into-three-subjects British route. ISE keeps the door open: a student can finish on the American high-school diploma or opt into the IB Diploma at Grade 11. If you want that choice deferred to age 16, ISE. If you want the committed A-Level path, Rugby.
Rugby publishes a large campus, boarding and a broad activities offer. ISE publishes a student-to-teacher ratio below 8:1 but not current grade or graduating-cohort sizes. Ask both schools for the proposed class, senior subject cohorts and activity participation. A large campus and a low ratio are useful inputs, but neither proves the peer experience or individual attention this pupil will receive.
Rugby is built around the whole-person, sport-arts-academics model: an 80-acre site, four swimming pools including a 50-metre Olympic pool, and the Webb Ellis Centre. ISE is calmer by design — a 306-seat Fine Arts Centre theatre, golf-course grounds, shared club pool and courts, and no attempt to be a sport monolith. If facilities and team sport are central to your child's life, Rugby. If a quieter environment is the point, ISE.
Only Rugby boards — from Year 6. ISE is day-only, so a family that needs boarding has no decision to make here. On price, ISE is roughly ฿353,000 a year cheaper at Sixth Form (฿646K vs ฿999K), and its one-time entry cost is far lower — a ฿90,000 enrolment fee plus a refundable ฿50,000 deposit, against Rugby's ฿200,000 acceptance fee plus refundable ฿100,000 student deposit. The cumulative difference depends on entry year, extras and future fee changes, so model the child's actual remaining years. For a day family where budget is the swing factor, ISE.
Both schools publish 2026/27 fees, so begin with standard tuition for the child’s exact stage. ISE runs ฿357,600–฿646,000; Rugby runs ฿345,000–฿999,000. The lowest Rugby figure is a half-day early-years option and does not show the cost of later primary or secondary education. The highest figures describe different qualification systems—ISE’s Grade 11–12 American/IB route and Rugby’s Year 12–13 A-Level route. Compare the child’s actual entry class before using either endpoint.
Keep annual-payment discounts separate. Each school publishes conditions for paying early, and those savings change cash timing as well as price. Write standard tuition on the first line, the discount on the next, and the qualifying date and refund rule beside it. A family unable to pay the full year before the deadline should not use the discounted figure as its working budget.
ISE’s tuition excludes lunch, bus, uniform and IB examination fees. Add its application, non-refundable enrolment, refundable security deposit and any assessed EAL cost. Rugby’s tuition includes textbooks, lunches and snacks, an annual residential trip and standard external examination entry, but families still need to add application, acceptance, refundable student deposit, activities outside the included programme, transport, uniform, music and any EAL or Support for Learning charge. For a boarder, add the chosen boarding pattern and boarding deposit.
ISE’s American route can lead to its high-school diploma or the IB Diploma. Rugby’s British route leads through IGCSE to A-Level. Ask each school for the current subject list, entry prerequisites, timetable constraints, counselling sequence, examination arrangements and recent cohort context. The child needs an available combination that supports their intended university direction; a famous qualification name does not guarantee every subject will run.
For a pupil joining in secondary, ask how prior study maps to the new route. Prior American coursework, an IGCSE sequence and IB preparation organise content differently. Admissions should identify any bridging work, courses that cannot be joined mid-cycle and the latest sensible entry point. Ask Rugby whether entry into the second year of an examination course is available for this pupil, and ask ISE what preparation is required for its IB option.
Rugby publishes boarding from age ten with part, weekly and full patterns; ISE is day-only. Request Rugby’s current boarding handbook, included nights, weekend and holiday routine, prep supervision, medical care, guardianship, device rules, excursions and extra charges. Visit the relevant house during an ordinary week and meet the adult responsible for the child’s age group. A boarding tariff describes accommodation and services, not whether the residential routine suits this pupil.
For a day pupil, compare school scale directly. Rugby publishes a large campus, extensive facilities and a broad activity programme. ISE publishes a student-to-teacher ratio below 8:1 but not current class or graduating-cohort sizes. Ask both schools for the proposed class size, senior subject cohort, activity participation and how a new pupil is integrated. A small ratio and a large campus are starting points, not conclusions about daily attention or peer fit.
Run both routes from the real home address during school traffic and request exact bus quotes, pickup windows, ride duration and late-activity returns. ISE’s Bowin position may suit Sriracha, Laem Chabang and industrial-corridor families; Rugby’s Bang Lamung location creates a different catchment. Put weekly travel hours beside tuition and boarding nights so the family can see the routine it is buying.
ISE is not for a family requiring boarding or a committed A-Level route. Rugby is not for a family seeking an American curriculum or an IB Diploma option. Neither should be chosen from facilities or tuition alone. The defensible offer names the class, complete cost, usable qualification subjects, support, transport and residential or day routine for this child.
