ISC vs
EFIP.

Same age span.
Different setting.

The fee rows below use each school’s published 2026/27 standard annual tuition, not a discounted annual-payment figure. That makes the comparison honest, but it does not make the first-year bill identical: registration, deposits and unpriced extras still need a dated admissions quote.

The range endpoints are for different years. A family comparing Reception, for example, should compare ISC’s Reception row with EFIP’s applicable early-years row, then add mandatory registration and any services the family will actually use. The lower published EFIP tuition does not prove the lower total for every child or commute.

Choose the teaching system,
not a language label.

ISC and EFIP serve different educational intentions. ISC publishes the English National Curriculum through Year 6, with English as the organising classroom language and Thai alongside it. EFIP publishes a French national pathway, with French as the medium and additional language provision. A family should not describe this as two international schools with different foreign-language classes. The language choice affects literacy, subject vocabulary, assessment, homework and the easiest future transfer system.

Ask each admissions team for a sample timetable for the exact class. At ISC, identify how English National Curriculum objectives are taught and assessed, how Thai fits into the week and what happens when a child needs English as an Additional Language or learning support. At EFIP, identify how much of the ordinary day is taught in French, how English and Thai are scheduled, and how FLSCO or intensive-French support changes a newcomer’s timetable. The child’s language placement should be written into the offer rather than inferred from a general programme page.

During a visit, spend time in the proposed year group. Listen to the language used for explanations, pupil discussion and feedback. Look at reading and writing expectations, independent work, transitions between subjects and how a teacher includes a pupil who is still acquiring the classroom language. Ask for anonymised work samples from the beginning and end of the year. Those observations will tell parents more than a curriculum logo or a multilingual list.

Plan Year 7
before Year 6.

ISC’s published span ends after Year 6. That can be entirely workable for a family that values the primary setting and wants to choose secondary school later, but the transfer is part of the decision from the beginning. Ask which reports, assessments and references ISC supplies, how it prepares pupils for different receiving curricula, when local secondary applications normally open and how families are advised. Add likely application and registration charges at the next school to the longer-term budget.

EFIP offers the possibility of continuing within a French pathway through Terminale, but parents should still confirm the delivery model grade by grade. Its record distinguishes currently homologated levels from CNED-supported upper grades. Ask the school to map the child’s proposed entry class through the family’s intended leaving point, identify the status of each relevant stage, explain where examinations are entered and show how records transfer to France or another French-system establishment.

All-through continuity is valuable only when the later curriculum remains the intended route. Primary-only education is attractive only when the family accepts another admissions process. Put the next likely move beside the current offer: expected year, curriculum, location, transition work and probable entry costs. That turns an abstract age-range difference into a practical family plan.

Use the same child,
year and payment basis.

Both schools publish 2026/27 fees, but ISC’s commonly shown annual-payment figures include a 3% prepayment saving. Its standard tuition is ฿180,000–฿370,800; the discounted range is ฿174,600–฿359,676. EFIP publishes standard tuition of ฿175,000–฿235,000. Begin the worksheet with standard tuition on both sides and show ISC’s discount separately with the qualifying payment date. A discount is relevant only if the family can meet its cash-flow and refund conditions.

Do not compare the endpoints without the child’s class. ISC’s lower figure belongs to a half-day early-years option, while its upper figure belongs to Years 3–6. EFIP’s range spans early years through the end of secondary. Admissions should confirm the exact proposed placement first, then provide the corresponding tuition row. Age and year-group naming do not map automatically between the English and French systems.

For the first year, ISC publishes a ฿3,000 application fee, ฿70,000 registration for a first child and ฿2,000 annual insurance. EFIP publishes ฿50,000 first registration, ฿5,000 administration and a ฿4,000 new-pupil uniform package. Add meals, transport, books, uniforms, activities, trips, examinations, visa support and required language or learning support. Mark each line mandatory, optional, refundable, annual, termly or one-time.

Support prices need their exact school labels. ISC publishes a combined English as an Additional Language / Learning Support range of ฿21,000–฿70,000 a year. EFIP publishes a ฿20,000 intensive-French supplement for relevant non-French-speaking pupils but no general learning-support tariff. Ask what assessment triggers a charge, how many sessions it buys, who reviews progress and when the pupil can exit support. These are not interchangeable services simply because both add to the invoice.

Price the route
as well as the seat.

ISC’s Banglamung location and EFIP’s Huai Yai campus can create very different school days from the same home. Run each route during actual drop-off and collection windows. Ask both schools for the exact bus stop, pickup time, ride duration, return arrangements after clubs and annual fare. EFIP publishes ฿35,000 one-way or ฿46,000 return transport; ISC’s record publishes a much wider zone-based annual range of ฿52,580–฿200,000.

A high transport quote may reflect distance, but price alone does not show the child’s time on the vehicle. Put weekly travel hours into the comparison beside tuition. If parents will drive, include fuel, tolls, work disruption and the feasibility of collection when the child is ill. A school that is stronger on paper can become a poor fit when the ordinary weekday is unsustainable.

Make both offers
child-specific.

Send the same dossier to both schools: recent reports, age, current curriculum, languages used at home, reading and writing profile, any support plan, intended start date, home address and likely future destination. Request a reply naming the proposed class, assessment steps, language placement, required support, standard tuition, mandatory charges, discount conditions, transport and withdrawal terms. Save the dated reply with the published fee schedule.

At ISC, ask how the pupil will progress through the remaining primary years and prepare for Year 7. At EFIP, ask for the grade-specific homologation or CNED position, French-entry support and later examination route. If either answer relies on a future discussion, record it as an unresolved condition before paying. “Admissions will advise later” is not equivalent to a confirmed pathway.

Rule out the wrong
structure early.

ISC is not an all-through secondary solution. It is a British-primary option through Year 6. A family requiring one campus through IGCSE, A-Level, IB Diploma or another senior qualification must plan a transfer. ISC may still be the stronger immediate classroom choice, but only when parents accept that next step and budget for it.

EFIP is not the natural option for a family seeking English-medium British education. Its value lies in French-system continuity. A beginner in French needs a realistic placement and support plan, while an older pupil needs written clarity on the exact homologated or CNED-supported arrangement. The AEFE relationship should be understood at the child’s grade rather than treated as a single undifferentiated label.

Neither school should be selected from the lowest tuition number. The defensible choice is the offer whose classroom language, full annual cost, commute, support plan and next transition all fit the same child.

Decision record to keep before paying

Write a one-page family decision record after both visits. It should name the proposed year group at each school, teaching language, weekly support, standard and discounted tuition, first-year cash due, recurring extras, transport time, withdrawal terms and next required transfer. Add the source date beside every figure. This makes it easy to spot where one attractive feature is masking an unresolved cost or pathway condition.

Include three child-specific observations rather than general impressions: how the pupil responded to the classroom language, whether the level of work looked accessible but challenging, and whether the daily journey left a workable afternoon. If a trial, assessment or second visit is available, use it to resolve the largest uncertainty. Do not let a polished campus tour answer a question about language readiness or Year 7 progression.

Review the record again before each major stage. An ISC family should bring the Year 7 search forward as the child approaches upper primary. An EFIP family should reconfirm the relevant grade’s delivery and examination arrangements as the pupil moves into secondary. The original choice can be sound without becoming permanent; scheduled reviews protect the child when family plans, language needs or available pathways change.
