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. El Dream publishes an English-medium route from K3 through Grade 12 using A.C.E., at ฿207,200–฿290,000 tuition. Grade continuity, qualification evidence and compulsory extras matter as much as the headline gap.

Both tuition schedules are dated 2026/27, so align the child's proposed class rather than the endpoints. Request SISB’s entry, resources, meals, ELS and transport rows alongside El Dream's application, registration, diagnostic test, lunch, textbooks, ESL, bus, uniform, trips and examinations.
SISB publishes 2026/27 tuition of ฿401,700–฿789,300. El Dream publishes 2026/27 tuition of ฿207,200–฿290,000 plus application, registration, diagnostic testing, lunch, textbooks and any required ESL.
SISB moves from EYFS and Singapore Primary into Cambridge IGCSE and AS/A-Level. El Dream uses the self-paced A.C.E. Christian curriculum through Grade 12.
SISB’s tariff reaches Grade 12 while 2026/27 new applications stop at Grade 10. El Dream families must verify the leaving credential, university-recognition route, diagnostic placement and every compulsory extra.
The schools overlap from age three through Grade 12, yet their scale, language patterns and exit routes differ. SISB combines English, Thai and Mandarin with Singapore and Cambridge stages; El Dream 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. El Dream publishes K3 through Grade 12 with A.C.E. and optional ESL support.
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 diagnostic placement and the leaving credential 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.
El Dream records English as the medium alongside Thai. Ask how English proficiency is assessed and how required ESL connects to self-paced mainstream 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.
El Dream publishes ฿207,200 for K3–K5, ฿230,000 for Grades 1–3, ฿250,400 for Grades 4–6, ฿269,600 for Grades 7–9 and ฿290,000 for Grades 10–12. Application is ฿2,000, registration ฿40,000 and diagnostic testing ฿2,000–฿5,000.
El Dream prices lunch at ฿24,000 in Kindergarten or ฿28,000 in Grades 1–12, textbooks at ฿13,000–฿17,000 and required ESL at ฿60,000 yearly. 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.
El Dream's A.C.E. pathway reaches Grade 12. Ask what diploma or transcript pupils receive, how universities recognise it and where recent graduates 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. El Dream publishes ESL at ฿60,000 yearly when required but no separate 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.
El Dream publishes A.C.E. through Grade 12. Ask what leaving credential current pupils receive, how course completion is recorded and what university counselling is provided.
For either school, request anonymised subject-choice forms, a sample transcript, the examination calendar and the counselling timeline.
El Dream appears in OPEC as registered international school 1120700015. 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. El Dream does not publish a sibling discount.
Ask El Dream to state any concession in writing and keep it separate from the published tariff.
SISB is in Nong Taphan, Ban Khai; El Dream is in Nong Pla Lai in Banglamung. Drive both routes at arrival and collection times, including work and sibling stops.
El Dream 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 El Dream, trace English-medium classwork into the self-paced A.C.E. pathway and ask how ESL pupils 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. El Dream prices lunch, textbooks and required ESL 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; El Dream is in Nong Pla Lai, 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. El Dream'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 El Dream'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 El Dream, include application, registration, diagnostic test, lunch, textbooks, ESL, 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.
El Dream publishes much lower headline tuition at every broad stage. Both schedules are dated 2026/27, but their curricula and inclusion sets differ, so compare personalised complete totals and qualification routes before ranking.
SISB publishes Cambridge IGCSE and AS/A-Level after its Singapore stages. El Dream does not publish a Cambridge route; it uses A.C.E. through Grade 12.
SISB publishes ages 2–18, with 2026/27 new applications through Grade 10. El Dream publishes ages 3–18 and K3 through Grade 12.
Ask for grade availability, tuition, application, assessment, enrolment, deposit, resources, meals, transport, trips, devices, ELS and refund terms.
Include tuition, application, registration, diagnostic testing, lunch, textbooks, required ESL, bus, uniform, trips, examinations, other support and refund terms.
Use the decision framework above to weigh curriculum, fees, continuity, location and your child’s fit.
