Before you decide

Choose the system, then price the year.

What needs planning?

SISB’s tariff reaches Grade 12 while 2026/27 new applications stop at Grade 10. Sirasartsuksa families must verify the fee year, discount eligibility, current Primary 4 operation and the next-school transfer after primary.

Two all-through routes. Different credentials.

Match the actual attendance offer

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. Sirasartsuksa's About page describes Nursery through Primary 4, while its fee page stops at Primary 3 and its linked Primary 4 timetable was created in 2019 without a current academic-year label.

Do not treat the Primary 4 label as proof that the class operates now. Request placement, a current timetable, cohort size, fee quote and the written transfer route after the last operating primary grade.

Make language exposure visible

SISB records English, Thai and Mandarin. Ask for weekly allocation, subject language, newcomer support and the transition from Singapore stages into Cambridge qualifications.

Sirasartsuksa records Thai and English. Ask which subjects are taught in each language at the proposed stage, how English proficiency is assessed, what Thai literacy level is expected and how newcomers receive support.

At both visits, request anonymised work and the report format in each teaching language. Observe how teachers explain unfamiliar tasks and whether translation supports learning or merely task completion.

Build complete first-year totals

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.

Sirasartsuksa's undated page publishes discounted annual tuition of ฿47,400 for Nursery, ฿52,100 for K1, ฿57,500 for K2–3 and ฿69,300 for P1–3. Registration is ฿8,000 for Nursery or Kindergarten and ฿12,000 for Primary. Ask for the undiscounted annual total and written eligibility conditions.

The school lists snacks, lunch, insurance, swimming, facilities, computer, activities, stationery, supplies, Intensive English and primary enrichment as included. Uniforms, PE kit, textbooks, school bag, blanket, summer semester, October Camp and after-school care are excluded or separately charged but unpriced.

Plan both transfer points

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.

Sirasartsuksa's current published runway ends at Primary 3 fees, with Primary 4 operation unconfirmed. Ask which receiving schools families use, what records are supplied, how Thai and English attainment is documented and whether pupils need an entrance examination or additional preparation.

Rehearse relocation after two years. Request the transcript, curriculum map, language evidence, grading scale and teacher references each school would supply.

Audit support without assumptions

SISB publishes ELS at ฿20,000–฿30,000 per term. Sirasartsuksa does not publish a usable language- or learning-support tariff in the sources reviewed.

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.

Test continuity with present evidence

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.

Sirasartsuksa does not publish a current secondary route. Ask whether Primary 4 operates in the intended year, when families must apply elsewhere, which receiving curricula are common and what transition support is included.

For either school, request anonymised work, a sample transcript, the assessment calendar and a written progression map.

Compare registration and curriculum claims carefully

Sirasartsuksa appears in Thailand's Office of the Private Education Commission directory, which is useful evidence of the school record but does not turn its Thai bilingual programme into a Cambridge or British curriculum. No campus-level accreditation for SISB Rayong appears in the sources reviewed.

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 regulatory registration separate from curriculum, examination and teaching-quality claims.

Model discounts without inventing them

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 sources reviewed for Sirasartsuksa do not give a standard annual-payment or sibling discount.

Ask Sirasartsuksa to state any current concession in writing and keep it separate from the undated standard tariff.

Test the real family week

SISB is in Nong Taphan, Ban Khai; Sirasartsuksa is in Amata City. Drive both routes at arrival and collection times, including work and sibling stops.

Sirasartsuksa advertises bus service without a current public price, and neither school supplies a comparable address quote. Ask for pickup windows, vehicle time, supervision and the exact address price. Both schools are day-only.

Finish the offer meeting

  1. Placement: exact class, live operation and next class.
  2. Learning: language allocation, programme map, work and reports.
  3. Cost: acceptance cash, first year and recurring year.
  4. Support: provision, staffing, review and price.
  5. Transition: SISB’s Singapore-to-Cambridge sequence or Sirasartsuksa's Thai-English Ministry pathway.

Save offers, fee schedules, calendars and placement answers together.

What to observe during a visit

Test a normal morning

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.

Compare learning evidence

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 Sirasartsuksa, inspect work in Thai and English and trace how its bilingual programme covers the Thai Ministry learning standards.

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.

Check care outside lessons

Confirm arrival supervision, meals, allergies, illness procedures, late collection and activities. SISB prices meals and resources separately. Sirasartsuksa publishes that food and bus services exist but not what a current family at a specific stage and address will pay, so both require a written inclusion list.

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.

Separate address from commute

SISB is in Nong Taphan, Ban Khai; Sirasartsuksa is at 700/4 Moo 1, Khlong Tamru inside Amata City Chonburi Industrial Estate. Verify each entrance, transport route and contract address before payment. Test gate queues, shift traffic, parking and the return journey.

Both are described as day schools in the sources reviewed. Families requiring residential care should treat that as a non-fit.

Write a conditional decision

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 international primary sequence and Sirasartsuksa's Thai national route with intensive English create different language and transfer demands. Before age eleven, Sirasartsuksa families need a receiving-school plan because no current secondary route is published.

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 Sirasartsuksa's fee year, food, bus, uniform, book, activity and examination costs 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.

Before applying
Which school publishes lower tuition?

Sirasartsuksa publishes much lower headline tuition, but its schedule is undated and several extras are unpriced. Confirm a current written offer before ranking it against SISB's dated 2026/27 schedule.

What should a SISB quote include?

Ask for grade availability, tuition, application, assessment, enrolment, deposit, resources, meals, transport, trips, devices, ELS and refund terms.

What should a Sirasartsuksa quote include?

Ask for academic year, stage, tuition, combined entry charges, food, bus, books, uniform, activities, examinations, language support and refund terms.
