Bangkok: British Curriculum Schools Guide
Thirty-six schools, fees from US$2,000 to US$35,000, and a results picture that ranges from world-class to completely opaque.
Originally published: 25 March 2026 · 10 min read
TL;DR
- Bangkok has 36 British curriculum schools, but the label covers everything from full IGCSE-to-A-Level pathways to schools that switch to IB at 16.
- Fees for the oldest year groups: US$3,000 (Rising Oaks) to US$35,000 (Shrewsbury, Wellington). Median around US$16,000.
- Shrewsbury leads on IGCSE (74% A\*/A); Harrow leads on A-Level (70% A\*/A). Both 2025 figures.
- Five BSO-accredited schools: Brighton and St Andrews (Gold/Outstanding), Harrow, King's, and Traill (Meets Standards).
- Patana, St Andrews, and Ascot switch to IB at sixth form. Check what your child will actually sit at 18.
- We could not find published exam results for most mid-range and budget schools.

The market at a glance
Bangkok counts 36 schools on the ISG database that list "British" as a curriculum, making it the single largest curriculum group in the city. That number deserves some scepticism. The label covers everything from elite offshoots of famous English public schools (Shrewsbury, Harrow, Wellington, Brighton, King's) to bilingual schools using a loosely British framework alongside Thai or Mandarin, to schools that follow the English National Curriculum until Year 11 before switching to the IB Diploma.
A British education in Bangkok remains cheaper than Singapore or Hong Kong, where top-tier fees exceed US$40,000. Bangkok tops out at US$35,000. At the other end, you can find a notionally British education for under US$5,000, though the product bears little resemblance to Shrewsbury or Harrow.
Who publishes results (and who does not)
Of the 36 British curriculum schools in Bangkok, we could find publicly available IGCSE or A-Level aggregate results for only ten. That is a transparency problem.
The schools that do publish tend to be the ones with strong results. This is not a coincidence. The mid-range and budget tiers are largely a results-free zone, at least in publicly accessible data. Some schools may share figures during visits or in prospectuses we could not access, but as a general rule, if a school charging US$15,000 per year does not appear to publish its exam results anywhere obvious, that is a data point when you are weighing options.
IGCSE results compared
The table below covers every Bangkok British school for which we could find 2025 IGCSE aggregate data. All figures are self-reported by the schools.
| School | % A*/A | % A*-B | % A*-C | Cohort | Source |
|---|---|---|---|---|---|
| Shrewsbury | 74% | -- | 97% | -- | School website |
| Harrow | 71% | 92% | 99% | -- | |
| Wellington | 70% | -- | 100% | -- | |
| Bangkok Prep | 58% | -- | 92% | 118 | School website |
| Bangkok Patana | 47% | 85% | -- | -- | |
| St Andrews (STA) | 40% | -- | 87%* | 180 |
*St Andrews reported 87% of students achieving 5+ A*-C grades, a slightly different metric.
The top three cluster around 70-74% A*/A, a level that would place them among the top-performing schools in the UK independent sector. Shrewsbury's 46% A* rate is particularly striking. Bangkok Prep's 58% on a cohort of 118 is creditable and, at a lower fee, represents the strongest value proposition in this group.
Schools with partial or qualitative data only
- Brighton College announced its "highest number of top IGCSE grades ever" in 2025 but we could not find aggregate percentages. One student achieved A*9 across all ten subjects. Historical data from 2021 suggests 86% A*-B, which would rank it among the leaders.
- King's College published subject-level highlights rather than aggregates: 86% A*/A in Mathematics, 91% in the sciences, and 100% in Art, Music, and Modern Foreign Languages. Impressive numbers, but without an overall figure, direct comparison is impossible.
- DBS (Denla British School) celebrated individual top performers (including a student with 10 A*s) but we could not find school-wide percentages.
- Bromsgrove reported "263 A* and A grades across subjects" and that "about 50% of students have got distinction and above" but provided no standard aggregate percentage.
Brighton and King's almost certainly have strong results given the subject-level data they share, but the absence of a headline number makes direct comparison impossible.
A-Level results compared
A-Level data is thinner still, partly because several schools switch to IB at sixth form, and partly because some A-Level programmes are too new to produce meaningful cohorts.
| School | % A*/A | % A*-B | Pass rate | Cohort | Year | Source |
|---|---|---|---|---|---|---|
| Harrow | 70% | 90% | 96.7% | -- | 2025 | |
| Shrewsbury | 64% | 83% | -- | 129 | 2025 | School website |
| Wellington | 61% | 86% | -- | -- | 2025 | |
| DBS | 55% | 71% | 100% | -- | 2024 | School website |
| Bangkok Prep | 52% | -- | 98% | 95 | 2025 | School website |
| Brighton | -- | 75%** | 100% | -- | 2024 | CanCham Thailand |
**Brighton's 75% A*-B is from 2024; 2025 described as "record-breaking" but no aggregates published.
Harrow leads with 70% A*/A, its "best results in 27 years", with 18 students achieving three or more A* grades. Shrewsbury follows at 64%, with an A* rate alone of 39%. All five schools outperform the UK national average of 28.2% A*/A. Bangkok Prep at 52% and US$23,000 is the value play.
The British-to-IB switch: read the small print
"British curriculum" does not always mean your child will sit A-Levels. Several schools follow the English National Curriculum through IGCSE and then switch to the IB Diploma at sixth form:
- Bangkok Patana: IGCSE then IB only. 2025 IB average of 35 points, 99% pass rate.
- St Andrews (STA): IGCSE then IB Diploma/IBCP. 2025 IB average 33 points, 95% pass rate.
- Ascot, Satit Bilingual, and SISB similarly lead into IB rather than A-Levels.
Both pathways are accepted by UK universities, but direct comparison is problematic: Patana's 35-point IB average and Shrewsbury's 64% A*/A at A-Level are both excellent but measure different things. See our IB Schools Bangkok guide.
Fee tiers
Fees below are for the oldest year groups in US dollars, from 2025/2026 schedules. Baht converted at ฿35.5 = US$1.
Ultra-premium: US$29,000-35,000
| School | Fee range | Students | Publishes results? |
|---|---|---|---|
| Shrewsbury | US$19,000-35,000 | ~2,000 | Yes |
| Wellington | US$18,000-35,000 | 1,500 | Yes |
| Harrow | US$4,000-30,000 | ~1,900 | Yes |
| King's College | US$17,000-30,000 | -- | Partial |
| Brighton (KK) | US$17,000-29,000 | -- | Partial |
| Brighton (Vibhavadi) | US$17,000-29,000 | 500 | Partial |
| DBS | US$15,000-29,000 | ~900 | Yes |
King's College fee data requires a note: the ISG database recorded US$1,000, which is plainly incorrect. The school's own fee schedule lists ฿616,000 to ฿1,063,000 per year (roughly US$17,000 to US$30,000). Harrow's wide range (US$4,000-30,000) reflects its Early Years programme; senior school sits at the top end.
Shrewsbury and Wellington charge the most. Harrow is the only school in this tier offering boarding. DBS, opened in 2018, is arguably the best-value entry given its 55% A*/A on its first A-Level cohort.
Premium: US$21,000-28,000
| School | Fee range | Students | Notes |
|---|---|---|---|
| Bangkok Patana | US$14,000-28,000 | 2,300 | IGCSE then IB. Not-for-profit |
| St Andrews (STA) | US$11,000-24,000 | ~2,300 | IGCSE then IB. Nord Anglia |
| Bangkok Prep | US$8,000-23,000 | 1,700 | Full A-Level pathway |
| SISB | US$11,000-23,000 | ~4,700 | British/IB. Largest in cohort |
| St Andrews S107 | US$10,000-22,000 | ~2,000 | Separate campus from STA |
| Bromsgrove | US$10,000-21,000 | ~500 | Day and boarding |
Bangkok Patana stands out as the only not-for-profit in the premium or ultra-premium tiers. Founded in 1957, it is the city's oldest international school, though its switch to IB at sixth form means it does not feature in our A-Level comparison. Bangkok Prep is the value pick: US$23,000 with 52% A*/A at A-Level.
Mid-range: US$10,000-20,000
Fourteen schools spanning bilingual programmes (Amnuay Silpa, British Mandarin), Australian-British hybrids, Singaporean-British blends, and straight British curriculum schools (Traill, Aster, Charter, RBIS). Results data for this tier is almost entirely absent. Traill is the exception: it holds BSO accreditation (inspected March 2025) and charges US$16,000 for the oldest year groups, making it the obvious pick for families wanting external validation at a moderate price.
Budget: under US$10,000
| School | Fee range | Students | Notes |
|---|---|---|---|
| Modern International | US$7,000-9,000 | 1,800 | British/Mandarin |
| Glory Singapore | US$6,000-8,000 | -- | Singaporean blend |
| IPS | US$5,000-8,000 | ~800 | British curriculum |
| British Mandarin | US$7,000 | -- | Bilingual |
| Rising Oaks | US$2,000-3,000 | -- | Up to Year 11 only |
At these prices, you are getting a different product. We could not find published exam data for any school in this bracket.

Results per dollar: the value question
The table below compares schools that publish A-Level results, using maximum annual fees and reported A*/A percentages.
| School | Max fee (senior) | A-Level A*/A | Cost per 1% of A*/A |
|---|---|---|---|
| Bangkok Prep | US$23,000 | 52% | US$442 |
| DBS | US$29,000 | 55% | US$527 |
| Harrow | US$30,000 | 70% | US$429 |
| Wellington | US$35,000 | 61% | US$574 |
| Shrewsbury | US$35,000 | 64% | US$547 |
Harrow and Bangkok Prep are the most efficient spenders. Harrow delivers the highest A-Level results in the city at US$5,000 less per year than Shrewsbury or Wellington. Bangkok Prep is the budget champion: 52% A*/A for US$23,000.
A crude metric that ignores selectivity, pastoral care, and facilities, but a starting framework. Most mid-range and budget schools do not appear to publish results, making value comparison outside the top tier impossible.
BSO inspections and accreditations
British Schools Overseas (BSO) is a voluntary UK Department for Education inspection scheme, the closest thing to Ofsted for British schools abroad. As of March 2026, five Bangkok British schools hold BSO accreditation:
| School | Last inspected | Outcome | Inspector |
|---|---|---|---|
| Brighton College | Nov 2023 | Gold / Outstanding | EDT |
| St Andrews (STA) | May 2024 | Gold / Outstanding | EDT |
| Harrow | Mar 2023 | Meets Standards | GOV.UK |
| King's College | Mar 2024 | Meets Standards | GOV.UK |
| Traill | Mar 2025 | Meets Standards | GOV.UK |
BSO itself is pass/fail ("Meets Standards" or does not). The EDT additionally awards its own International Schools Quality Mark at Gold, Silver, or Bronze. Brighton and St Andrews both received Gold plus "Outstanding", the highest possible rating. EDT inspectors described Brighton's academic outcomes as "among the best in the world".
Notable absences: Shrewsbury, Wellington, DBS, Bangkok Prep, and Bromsgrove are not BSO-accredited. This does not mean they are substandard; BSO is voluntary. Shrewsbury and Wellington hold CIS accreditation and COBIS membership instead. DBS achieved COBIS Accredited Member status in October 2025. But if you specifically want UK government-adjacent inspection, the BSO list is shorter than you might expect.
New entrants and ones to watch
King's College opened in 2020 as the overseas arm of King's College School, Wimbledon. Its first A-Level cohort sat exams in 2025 (no aggregate published), but subject-level IGCSE data (86% A*/A Maths, 91% sciences) suggests it is performing at a high level. Holds BSO accreditation. One to watch.
Brighton College Vibhavadi is Brighton's second Bangkok campus, opened in Chatuchak. Same fees and curriculum as the Krungthep Kreetha campus. The brand's BSO Gold/Outstanding rating and "British International School of the Year" award (2024) add credibility, though the Vibhavadi campus needs to build its own track record.
DBS (founded 2018) graduated its first A-Level cohort in 2024 with 55% A*/A, above the UK independent school average of 49.4%. Achieved COBIS Accredited Member status in October 2025.
Methodology
Fee data collected from school websites and the ISG database in March 2026, converted at ฿35.5 = US$1. Exam results are self-reported by schools; no independent body collects or verifies Bangkok international school exam results. BSO data from the UK Government's published list. Accreditations cross-referenced against CIS, COBIS, and FOBISIA official listings. Where we could not find data, we have said so. Corrections welcome at [email protected].
The International Schools Guide is editorially independent. No school has paid for inclusion or favourable coverage.

FAQs
Which British school in Bangkok has the best exam results?
Based on 2025 published data, Shrewsbury leads at IGCSE with 74% A\*/A, while Harrow leads at A-Level with 70% A\*/A. Wellington is close behind in both metrics. However, several schools (Brighton, King's) publish only subject-level data, making full comparison impossible.
Do all British curriculum schools in Bangkok offer A-Levels?
No. Several schools that follow the British curriculum through IGCSE switch to the IB Diploma at sixth form, including Bangkok Patana, St Andrews, and Ascot. Others (Rising Oaks, Siam Singapore) only go up to Year 11 and do not have a sixth form at all. Check the post-16 pathway before enrolling.
What is BSO accreditation and which Bangkok schools have it?
BSO (British Schools Overseas) is a voluntary inspection scheme run by the UK Department for Education. Schools are assessed against British education standards. As of March 2026, five Bangkok British schools hold BSO accreditation: Brighton College (Gold/Outstanding), St Andrews (Gold/Outstanding), Harrow, King's College, and Traill (all Meets Standards).
How much do British schools in Bangkok cost?
For the oldest year groups, fees range from around US$3,000 (Rising Oaks) to US$35,000 (Shrewsbury and Wellington). The median across schools with published fees is approximately US$16,000. We could not find published fees for four schools. One-off registration and deposit charges typically add US$5,000 to US$12,000 on top of annual tuition.
Is it better to choose A-Levels or IB in Bangkok?
Both are well-served. A-Levels offer depth in fewer subjects; IB provides breadth across six plus core components. UK universities accept both. US universities tend to favour IB slightly, though A-Levels with good grades are accepted everywhere. See our [Bangkok IB guide](/insights/best-ib-schools-bangkok-results-rankings).
