This comparison is deliberately not a price ranking. SISB Rayong publishes a trilingual Singapore-to-Cambridge route from age two and dated 2026/27 tuition of ฿401,700–฿789,300. BPIS is secondary-only from age 11 and publishes an undated British IGCSE-to-A-Level tariff of ฿126,000–฿157,500. Confirm BPIS's current year and complete inclusion list before ranking.

The fee years do not match: SISB is dated 2026/27, while BPIS's tariff is undated. Request SISB’s grade, entry, resources, meals, ELS and transport rows alongside BPIS's current-year tuition, entry, books, uniform, supplies, extra classes, transport, trips, exams and support.
SISB publishes dated 2026/27 tuition of ฿401,700–฿789,300. BPIS publishes an undated live tariff of ฿126,000–฿157,500 plus ฿31,400 entry charges.
SISB moves from EYFS and Singapore Primary into Cambridge IGCSE and AS/A-Level. BPIS begins only at Year 7 and publishes a British secondary route through Cambridge IGCSE and A-Level.
SISB’s tariff reaches Grade 12 while 2026/27 new applications stop at Grade 10. BPIS families must verify the current fee year, grade operation, subject offer, Cambridge centre evidence and complete inclusion list.
The schools overlap only in secondary. SISB combines three languages and Singapore stages with Cambridge qualifications; BPIS starts at Year 7 and publishes a British IGCSE and A-Level route.
Ask both schools to state the child’s proposed class, start date, age cut-off and following year. SISB publishes Nursery through Grade 12 fee rows, though new applications stop at Grade 10; BPIS publishes Years 7–13 only.
A child below secondary age cannot use BPIS. For an older child, confirm the exact live grade, cohort, subjects and next-year progression before comparing price.
SISB records English, Thai and Mandarin. Ask for the weekly allocation, subject language, newcomer support and transition into Cambridge stages.
BPIS records English as the medium alongside Thai. Ask how Year 7–9 work prepares pupils for IGCSE, how English proficiency is assessed and which subjects are actually taught in English.
At both visits, request anonymised work and the report format. Observe how teachers explain unfamiliar tasks and support pupils new to English.
SISB’s 2026/27 tuition runs from ฿401,700 to ฿789,300. Application and assessment are ฿5,000 each, enrolment ฿220,000 and deposit ฿50,000. Resources are ฿30,500–฿84,000, meals ฿26,400–฿39,000 and ELS ฿20,000–฿30,000 per term.
BPIS publishes ฿126,000 yearly for Years 7–10 and ฿157,500 for Years 11–13, but the live page does not name an academic year. It combines application ฿200, registration/admission ฿30,000 and insurance ฿1,200 as ฿31,400 entry charges.
The fee page calls tuition all-inclusive, while the 2025/26 handbook says extra classes require payment and the school shop sells books, uniforms and supplies. Ask for transport, trips, exams and support too. Create current-year totals only from the written offer.
SISB publishes Cambridge IGCSE and AS/A-Level after its Singapore stages. Confirm which senior grades currently operate, accept newcomers and offer each subject.
BPIS publishes an IGCSE and A-Level route, but public destination evidence remains thin. Ask for current subjects, cohort sizes, completion routes, university counselling and campus-level outcomes rather than assuming every option runs regardless of demand.
Rehearse relocation after two years. Request the transcript, curriculum map, language evidence and teacher references each school would supply.
SISB publishes ELS at ฿20,000–฿30,000 per term. BPIS does not publish a usable language- or learning-support tariff in the current ledger.
If support matters, request the staff member, group size, minutes per week, review date, progress measure, exit criteria and price. Separate English acquisition from other learning needs.
Bring existing reports before assessment and ask admissions to state any limitations in writing.
SISB’s published sequence reaches Cambridge IGCSE and AS/A-Level, but the Rayong campus opened in 2023 and its 2026/27 new-applicant range stops at Grade 10. Ask which secondary grades are operating now, how many pupils are in each cohort, which IGCSE subjects are taught and when the first Rayong AS/A-Level cohort is expected.
BPIS publishes IGCSE and A-Level labels, but independent Cambridge evidence was not located. Ask which subjects run this year, what examination centre enters pupils, how timetable conflicts are handled and what university-counselling evidence the current cohort receives.
For either school, request anonymised subject-choice forms, a sample transcript, the examination calendar and the university-counselling timeline.
BPIS publishes a Cambridge pathway, but independent Cambridge accreditation evidence was not located in the current public sources; its Thai Ministry of Education status is also a school-published claim in the ledger. SISB’s current ledger record does not list a campus-level accreditation.
Ask each school for the campus-specific register or examination-centre evidence that applies to the child's programme, then compare the teacher, class size, homework and reporting cadence.
SISB publishes a 2% full-year tuition discount, sibling tuition discounts of 5% for the second child and 10% for later children, and a 20% enrolment reduction from the second child. The current BPIS ledger does not record a standard annual-payment or sibling discount.
Ask BPIS to state any current concession in writing and keep it separate from the undated standard tariff.
SISB is in Nong Taphan, Ban Khai; BPIS is near Sukhumvit-Pattaya Alley 81 in Nongprue. Drive both routes at arrival and collection times, including work and sibling stops.
Neither current ledger record publishes a usable transport tariff for this comparison. Ask for pickup windows, vehicle time, supervision and the exact address price. Both schools are day-only.
Save offers, fee schedules, calendars and placement answers together.
Arrive before the class begins and watch the transition from gate to room. Record how quickly the child separates, who welcomes them, which language adults use and whether the routine is understandable without repeated prompting. Ask what happens on a difficult morning and how parents are informed. A polished tour after children leave cannot answer these questions.
Ask for a starting assessment, mid-year report and anonymised work from the proposed class. At SISB, trace English, Thai and Mandarin into Singapore and Cambridge stages. At BPIS, trace Year 7–9 work into IGCSE and the later A-Level decision.
Record the balance of adult-led, child-initiated, individual and group activity during the visit. Ask how teachers adapt the same task for a child who is new to English, already reading or reluctant to join a group. The right environment is not defined by one teaching philosophy; it is the setting where staff can explain how this child will participate and progress.
Confirm arrival supervision, meals, allergies, illness procedures, late collection and activities. SISB prices meals and resources separately; BPIS's “all-inclusive” label needs a written inclusion list because its handbook identifies school-sold items and paid extra classes.
Place both calendars beside the family’s work calendar. Count closures that require alternative care and ask whether holiday programmes are offered, separately registered or guaranteed to enrolled pupils. A school-year tuition comparison does not capture care purchased during long breaks.
SISB is in Nong Taphan, Ban Khai; BPIS is in Nongprue, Banglamung. Verify each entrance, transport route and contract address before payment. Test gate queues, parking and the return journey.
Both schools are day-only in the current ledger. Families requiring residential care should treat that as a non-fit.
For each school, finish the sentence: “This place works if…” Include the quoted total, language routine, classroom fit, support availability, care hours, travel ceiling and next-school plan. Then write the conditions that would trigger a review. This prevents a single attractive feature from hiding an unresolved cost or transition risk.
Run the same exercise for two future dates. At age six, SISB can serve the child and BPIS cannot. At age eleven, compare SISB's growing Cambridge transition with BPIS's Year 7 entry, current subjects and support needs.
Before signing, compare the two schools’ invoice language line by line. Ask each admissions team to mark every compulsory, optional, refundable and one-time row, then calculate cash due before the first day, the complete first year and a normal later year. Keep BPIS's fee year and inclusion list open until the signed offer resolves them.
Also rehearse a mid-year move. Ask what notice is required, which reports and curriculum records would be released, how deposits are returned and whether prepaid services are refundable. Families using the Eastern Seaboard industrial corridor should test both routes at real collection time, because a lower fee cannot compensate for an unsustainable daily journey.
Ask how each school handles a mid-year departure before assuming either transfer will happen neatly at the end of a stage. Record required notice, reports supplied, outstanding-fee conditions and whether unused services can be refunded. A family expecting relocation should weight these documented terms alongside teaching and price.
Do not pay while a condition remains material and unanswered. Ask admissions to correct the offer email, retain both 2026/27 schedules and note who supplied every grade and support answer. That record makes the decision auditable.
BPIS publishes much lower headline secondary tuition, but its live tariff is undated and its inclusion evidence conflicts. Confirm a current written offer before ranking it against SISB's dated schedule.
Not in the same way. SISB combines Singapore and Cambridge stages; BPIS follows a British route through IGCSE and A-Level.
SISB publishes ages 2–18, with 2026/27 new applications through Grade 10. BPIS is secondary-only for ages 11–18, Years 7–13.
Ask for grade availability, tuition, application, assessment, enrolment, deposit, resources, meals, transport, trips, devices, ELS and refund terms.
Ask for academic year, year group, tuition, entry charges, books, uniform, supplies, extra classes, transport, trips, exams, support and refund terms.
Use the decision framework above to weigh curriculum, fees, continuity, location and your child’s fit.
