This comparison is deliberately not a price ranking. SISB Rayong publishes a trilingual international route from age two and 2026/27 tuition of ฿401,700–฿789,300. Hastin publishes an English-medium route from Pre-Nursery through Year 9 using the Oxford International Curriculum, at ฿169,500–฿229,500 tuition. Grade continuity, qualification evidence and compulsory extras matter as much as the headline gap.

Confirm that Hastin's Academic Year 2026 basis covers the same attendance period as SISB's 2026/27 quote. Request SISB’s entry, resources, meals, ELS and transport rows alongside Hastin's application, enrolment, meals, protection charges, visa processing, bus, uniform, trips and examinations.
SISB publishes 2026/27 tuition of ฿401,700–฿789,300. Hastin publishes Academic Year 2026 tuition of ฿169,500–฿229,500 plus application, enrolment, meals and annual protection charges.
SISB moves from EYFS and Singapore Primary into Cambridge IGCSE and AS/A-Level. Hastin uses the Oxford International Curriculum through Year 9.
SISB’s tariff reaches Grade 12 while 2026/27 new applications stop at Grade 10. Hastin families must verify the Year 9 transfer, next qualification, fee-year basis and every compulsory extra.
The schools overlap from the early years through Year 9, yet their scale, language patterns and exit routes differ. SISB combines English, Thai and Mandarin with Singapore and Cambridge stages; Hastin uses English as its medium alongside Thai.
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 2026/27 new applications stop at Grade 10. Hastin publishes Pre-Nursery through Year 9 with Oxford International Curriculum.
Do not translate Grade and Year labels by number alone. Request the placement test, class equivalence, current cohort and written progression route. For an older pupil, make the Year 9 transfer and next qualification first-meeting questions.
SISB records English, Thai and Mandarin. Ask for weekly allocation, subject language, newcomer support and the transition from Singapore stages into Cambridge qualifications.
Hastin records English as the medium alongside Thai. Ask how English proficiency is assessed and how English support connects to Oxford International Curriculum work.
At both visits, request anonymised work and the report format. Observe how teachers explain unfamiliar tasks and whether language support builds independent subject learning.
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.
Hastin publishes ฿169,500 for Pre-Nursery through Reception, ฿198,900 for Years 1–6 and ฿229,500 for Years 7–9. Application is ฿3,000 and enrolment ฿30,000.
Hastin prices mandatory Early Years meals at ฿5,000 per term, optional meals at ฿6,000 in Years 1–6 or ฿6,500 in Years 7–9, plus annual ฿1,000 property protection and ฿1,000 accident insurance. Bus, uniform, trips and external exams remain unpriced.
SISB publishes Cambridge IGCSE and AS/A-Level after its Singapore stages. Confirm which senior grades currently operate, accept newcomers and offer each subject at the Rayong campus.
Hastin's current pathway reaches Year 9. Ask which secondary schools accept the record, what placement evidence is supplied and where recent pupils progress.
Rehearse relocation after two years. Request the transcript, curriculum map, grading scale, exam evidence and teacher references each school would supply. A lower current bill may carry extra transfer preparation if the next school expects a different sequence.
SISB publishes ELS at ฿20,000–฿30,000 per term. Hastin 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.
Hastin publishes Oxford International Curriculum through Year 9. Ask how pupils are prepared for transfer and which qualifications they enter next.
For either school, request anonymised subject-choice forms, a sample transcript, the examination calendar and the counselling timeline.
Hastin appears in OPEC as registered international school 1120700016. SISB’s current ledger record does not list a campus-level accreditation.
Ask each school for the campus-specific register or examination evidence that applies to the child's programme, then compare teacher qualifications, class size, homework and reporting cadence. Keep registration separate from curriculum, qualification and teaching-quality claims.
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. Hastin does not publish a sibling discount.
Ask Hastin to state any concession in writing and keep it separate from the published tariff.
SISB is in Nong Taphan, Ban Khai; Hastin is in Pong in Banglamung. Drive both routes at arrival and collection times, including work and sibling stops.
Hastin does not publish a current bus tariff. SISB excludes transport from standard fees. Both schools are day-only, so request an exact address quote and test vehicle time rather than relying on straight-line distance.
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 Hastin, trace English-medium classwork into the Oxford International Curriculum pathway and ask how pupils new to English demonstrate readiness to join mainstream lessons.
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. Hastin prices meals and two annual protection charges outside tuition while bus and uniform remain unpriced, so model the child's actual routine rather than comparing tuition alone.
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; Hastin is in Pong, 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. Hastin's unpublished bus position makes route availability and price material; ask for pickup time, route duration, supervision and price in writing.
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, both schools may be usable, but SISB's Singapore primary sequence and Hastin's English-medium primary route require different evidence. At age eleven, compare live secondary subjects, cohort size, language support and the documented next qualification.
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. For Hastin, include application, enrolment, meals, protection charges, visa processing, bus and uniform.
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.
Hastin publishes much lower headline tuition, but its tariff is labelled Academic Year 2026 while SISB's is 2026/27. Confirm matched dates and complete totals before ranking.
SISB publishes Cambridge IGCSE and AS/A-Level after its Singapore stages. Hastin does not publish a Cambridge route; it uses Oxford International Curriculum through Year 9.
SISB publishes ages 2–18, with 2026/27 new applications through Grade 10. Hastin publishes Pre-Nursery through Year 9.
Ask for grade availability, tuition, application, assessment, enrolment, deposit, resources, meals, transport, trips, devices, ELS and refund terms.
Include fee year, tuition, application, enrolment, meals, protection charges, visa processing, bus, uniform, trips, examinations, support and refund terms.
Use the decision framework above to weigh curriculum, fees, continuity, location and your child’s fit.
