ISC vs
Belfry.

Shared curriculum does not
make them interchangeable.

Belfry and ISC both publish English National Curriculum primary pathways, so the comparison begins closer than a British-versus-French or international-versus-bilingual choice. Yet the shared label is only a starting point. Belfry publishes British EYFS and Key Stages 1–2 with a Montessori-informed approach in Ban Khai. ISC publishes English National Curriculum primary stages for ages 2–11 in Banglamung. Families should ask what the school day, language expectations, classroom routine and child support look like in the exact year group, rather than assuming that two British labels deliver the same experience.

Both published spans end after primary. That makes later-school planning a common task, not a reason to exclude either school. A family should ask each admissions team how it prepares children for a Year 7 transfer, what records and assessment information it provides, whether it has relationships with particular secondary schools, and how it supports a child whose future route may be Thai, British, IB or another international curriculum. The answer should not be treated as a promise of a place elsewhere; it is a way to see whether the school recognises the transition as part of its responsibility.

The important distinction may be daily fit. Ask Belfry what Montessori-informed practice means in the proposed year group and how it sits alongside the English National Curriculum. Ask ISC how it structures its early-years and primary progression, how it assesses a joining child, and what language or learning support it provides. Request a visit during an ordinary school day, not only an open-house tour. Watch the relevant class transition, ask how teachers communicate with parents and find out who a child sees when they need help. Those details give a more useful comparison than a curriculum badge alone.

Discounted and standard fees
are not the same number.

Belfry publishes 2026/27 standard annual tuition of ฿301,000–฿395,000 before its annual-payment discount. ISC publishes its annual figures with a 3% full-year prepayment discount included, while term payments total about 3% more. This means a parent should not place an ISC discounted annual number beside Belfry’s standard number and call the difference a like-for-like saving. Ask both schools for the same basis: standard tuition for the child’s exact year, the number of payments, any early-payment reduction and the final date for that reduction.

For early years, the programme and attendance pattern matter. ISC publishes separate early-years figures, including two-half-day and full-day options. Belfry publishes Nursery and Early Years levels under its own tariff. A lower number can reflect a different number of days or hours, not simply a cheaper school. Write the attendance pattern beside every amount. For primary, compare the exact year group rather than the widest range: ISC has different published figures across Reception, Years 1–2 and Years 3–6; Belfry separately lists Year 1, Year 2 and Years 3–6.

First-year cash is larger than tuition at both schools. ISC publishes application, registration and annual insurance amounts. Belfry publishes an application charge, non-refundable registration and a refundable deposit. A refundable deposit should still be budgeted as cash required, while a non-refundable registration fee should not be treated as recoverable. Ask about sibling rules, refund timing, notice periods and whether any charge changes for a mid-year entry. Save the answer with the fee document.

Meals, transport and support also need their own lines. ISC’s public record identifies meals, transport and learning support as separate; Belfry identifies catering, trips, clubs, events and optional services as extra. If a school does not publish a tariff, label the item quote-only. Ask whether food is optional, which transport zone covers the home, whether the fee is one-way or return, and what happens after clubs. For support, ask how it is assessed, whether it is compulsory and whether the fee is per term, per service or per hour.

The route to class
must work every day.

Ban Khai and Banglamung can create very different routines even for families living between Pattaya and Rayong. Test the school-day route at drop-off and collection, including rain, traffic and the child’s activities. Ask where a bus stops, whether it runs after clubs, what happens if a parent is late and how a child is supervised. A manageable weekend drive can become an exhausting term-time journey, particularly for younger children.

On a visit, take the same questions to both schools. Is there a place in the exact year group? What will the child’s first weeks look like? Which language and learning support is available? What is included in the invoice? How are parents kept informed? What happens at Year 6 when the family needs to plan the next school? Written answers matter because the public comparison is a starting point, not a contract.

Use the same checklist
with both schools.

First: which classroom routine and teaching approach fits the child now? Second: what is the exact annual cost on a standard, not mixed, payment basis? Third: which extras are compulsory? Fourth: can the family sustain the commute and activity schedule? Fifth: how will the school prepare the child for Year 7 transfer? Keep current fee documents, admissions emails, placement notes and payment terms together before any deposit is transferred.

The conclusion is practical rather than absolute. Belfry may suit a family whose geography fits Ban Khai and whose child responds to its Montessori-informed British primary approach. ISC may suit a family seeking its Banglamung English National Curriculum primary setting and published fee structure. Both require a later secondary plan. Choose the school that can explain the child’s daily fit, future transition and complete written cost most clearly.
