IB Results in Kuala Lumpur

Kuala Lumpur has a smaller dedicated IB Diploma market than Bangkok or Singapore. The curriculum mix leans British Cambridge, with IB Diploma offered as one of several sixth-form pathways at most schools that hold the authorisation. The 2024 global IB Diploma average was 30.32, pass rate around 80%. 24 of 45 is the bare pass. 38 to 40 is the band Oxford, Cambridge, the LSE and the top US selectives screen on. 32 to 36 opens most Russell Group, Australian Go8 and broad US options. Of eleven Kuala Lumpur schools holding IB Diploma authorisation, only seven publish a cohort average.

Ranked by published DP average

1. UCSI International School (Kuala Lumpur), 38 (2024)

UCSI International School on the UCSI University campus posts the highest verified Diploma average on this list, 38 points for the 2024 cohort, alongside Cambridge IGCSE on a compact senior cohort. Senior fees MYR 23,700 to 41,250, roughly a third of ISKL. Cohort size and pass rate are not publicly disclosed; the 38-point figure has to be triangulated with cohort detail at admissions.

2. Sri KDU School (Kota Damansara), 38 (2023)

Sri KDU has the deepest IB record in the city outside ISKL. 38 points in 2023, 37.0 in 2020 with a 100% pass rate and 90% scoring 35 or above. Seven points clear of the global average across multiple years, not a one-off spike. Senior fees MYR 24,460 to 76,810. IB Diploma runs alongside Cambridge A-Level.

3. Global Indian International School Kuala Lumpur, 37.4 (2025)

GIIS posts a 37.4-point IBDP average for the 2025 cohort, the highest most-recent figure on this list. The school sits in the Indian and British dual-stream category, with IB Diploma layered on at sixth form rather than as the sole exit qualification. That structure typically means a self-selected smaller IB cohort and a higher headline average. The broader 2025 picture, *77.4% of IGCSE entries at A\ or A**, points to an academically high-pressure environment across pathways.

4. Sunway International School Kuala Lumpur, 36.2 (2021)

Sunway International School published an IB Diploma average of 36.2 in 2021 with a 100% pass rate. The figure is the school's most recent public disclosure, four years old, so historical signal pending a fresh number. Sunway is curriculum-IB across its programmes, in the smaller subset of Kuala Lumpur schools that go IB without a Cambridge layer alongside.

5. IGB International School, 35 (2025)

IGB International School on Sierramas in Mont Kiara is the purest full IB continuum option in Kuala Lumpur, the only city school authorised for PYP, MYP, DP and CP. 2025 IB Diploma average 35, 100% pass rate. Senior fees premium at MYR 50,800 to 118,200, on a small school of around 400 pupils. A tight Diploma group where deep teaching and a homogeneous starting point compound.

6. Mont'Kiara International School, 34.4 (2025)

Mont'Kiara International School (M'KIS) publishes a 2025 IB Diploma average of 34.4 on a cohort that awarded 23 diplomas, highest individual score 42, 100% university acceptances. Sharper cohort numbers than most on this list. American in curriculum heritage at the lower years and IB Diploma at sixth form, an unusual structure in Kuala Lumpur.

7. Fairview International School (KL), 34.53

Fairview International School at Wangsa Maju publishes an IB Diploma average of 34.53 and a 100% pass rate maintained for seven consecutive years. One of the early IB schools in Malaysia and fully IB at all levels. The published figure is undated; the most recent single-year average and 2025 cohort size are the questions to ask the school directly.

8. The International School of Kuala Lumpur, 34.2 (2025)

ISKL is the heritage anchor of the Kuala Lumpur international market, founded 1965, around 1,800 students, with the largest IB Diploma cohort in the city. 2025 IB Diploma average 34.2 with a 93% pass rate, against 35 in 2024. IB Diploma and AP run side by side; 83% of 2025 AP entries scored 4 or 5. The 34.2 figure sits on the largest, least pre-selected senior cohort in Kuala Lumpur: a number drawn from breadth, not from a tight self-selected subset. Senior fees are the top of the market, MYR 70,200 to 143,400.

9. Nexus International School (Putrajaya), 33 (2025)

Nexus International School at Putrajaya posts a 2025 IB Diploma average of 33, with eight learners scoring above 40, alongside Cambridge IGCSE on a 650-pupil community. The 33-point average lands two and a half points above the global line; the eight 40-plus scorers carry the standout signal. Nexus is the Putrajaya choice rather than a central Kuala Lumpur one, which matters for commute and catchment.

How to read these numbers

Cohort size matters more than the average. A 38-point average on a self-selected cohort of 12 is a different signal from a 34-point average on a cohort of 90 across the full ability range. ISKL's 34.2 on the largest cohort in the city is arguably a more demanding result than UCSI's 38 on an undisclosed group.

A single year is not a pattern. Sri KDU at 38 in 2023 is interesting; Sri KDU at 37 in 2020 and 38 in 2023 is a pattern. Sunway at 36.2 in 2021 with no public update since is a stale data point. Three consecutive years tells you whether the result holds while the cohort turns over.

Pass rate is the floor, not the ceiling. A 100% pass rate at an IB school is mostly a sign that the school has not let weak students sit the exam unprepared. ISKL's 93% pass on the largest cohort in the city is more honest information than a 100% rate on a hand-picked group of twelve.

Top scorers and median are different conversations. Mont'Kiara's highest 2025 score was 42 on a 34.4 average. Nexus had eight learners above 40 on a 33 average. The ceiling is open at those schools while the median sits where the cohort sits.

Schools with no public DP results

Four schools in our directory hold IB Diploma authorisation in Kuala Lumpur and publish nothing on the IB side, or publish only Cambridge IGCSE and A-Level results alongside the IB badge.

• Cempaka International School at Damansara Heights runs IB Diploma alongside Cambridge A-Level; public disclosures focus on Cambridge.
• Aspiration International School lists IB MYP and DP across its curriculum mix with no public exam data.
• Stella Maris International School lists IB Diploma alongside Cambridge and British pathways; published results to date are SPM-side.
• Adcote Matrix International School lists IB Diploma but publishes only IGCSE and A-Level cohort numbers.

A school that lists IB Diploma but cannot give you its average, pass rate and cohort size from the last three years in writing has told you something about how serious the IB stream is inside the wider operation. Authorisation is a floor, not a result.

FAQs

What is a good IB Diploma average for a Kuala Lumpur school?

The 2024 global average was 30.32, pass rate around 80%. A strong Kuala Lumpur school produces a cohort average in the 34 to 38 range with a pass rate at or above the global line. Every Kuala Lumpur school with a publicly verifiable figure clears the global average by three to eight points.

Which Kuala Lumpur school has the largest IB Diploma cohort?

ISKL runs the largest IB Diploma cohort in the city, drawn from a senior school inside an 1,800-pupil community. The 34.2 average in 2025 sits on a less pre-selected group than the smaller cohorts at IGB, M'KIS or UCSI.

Why do some Kuala Lumpur schools list IB Diploma but publish only IGCSE results?

Several Kuala Lumpur schools hold IB Diploma authorisation while running it as one of two or three sixth-form pathways alongside Cambridge A-Level. Where the British pathway is the larger or stronger of the two, that is where the public communications tend to land. Cempaka and Adcote Matrix are clear examples.

How do Kuala Lumpur IB results compare to Singapore or Bangkok?

Kuala Lumpur's top published averages, 37 to 38, sit in the same band as Bangkok's top schools (NIST 37, SISB 37.4) and slightly below Singapore's leaders (Tanglin Trust 39.6, NPS International 38.9). The Kuala Lumpur range is narrower because the published-data sample is smaller. Top-end Kuala Lumpur IB fees are materially lower than Singapore and broadly comparable to Bangkok.

Are higher-fee schools getting better IB results in Kuala Lumpur?

Not directly. The highest-fee IB school in the city, ISKL, posts a 34.2 average. The lower-fee UCSI and GIIS post the strongest most-recent averages. Selectivity and cohort size explain more of the variance than fee level.

Sources: each school's official published academic results disclosures and admissions communications; the IB Organisation's 2024 worldwide statistical bulletin (global Diploma average 30.32, worldwide pass rate ~80%); IB World Schools authorisation directory for PYP, MYP, DP and CP status across Kuala Lumpur schools; The Intelligence Kuala Lumpur school profiles for fee bands, cohort scale and curriculum mix. Where a school publishes only an undated average, the figure is treated as historical signal pending fresh disclosure.
