The IB Route in Singapore, Explained

The International Baccalaureate Diploma Programme (IBDP) — the alternative to A-Levels, taken instead of (not after) the SEC track at some schools

Where IB fits: two ways in

The IB Diploma sits at the same stage as A-Levels (age ~17–18). In mainstream Singapore schools you reach it two ways:

Route 1
via PSLE (IP)
PSLE
low AL score needed — IP cut-offs are the most selective
6-year IP
skips the SEC exam entirely
IBDP exam
at end of Year 6
Route 2
after the SEC
SEC (O-Level)
4 years, aggregate-based admission
2-year IBDP
instead of a JC — e.g. SJI admits via the same JAE exercise
IBDP exam
same diploma

Both routes end at the same exam and diploma, and both lead on to university (local and overseas). A third way: international schools offer the IBDP privately at much higher fees.

Which mainstream schools offer it

Only a handful of MOE-side schools run the IB Diploma — all sit the November exam session:

SchoolHow
ACS (Independent)6-year IP to IBDP; Methodist Girls’ School IP students join ACS(I) for Years 5–6
St Joseph’s Institution (SJI)Dual track: 4-year SEC course or 6-year IP to IBDP; also admits O-Level/SEC graduates into the 2-year IBDP via JAE
School of the Arts (SOTA)6-year arts + academics programme ending in IBDP or the career-related IBCP; no SEC track at all
Singapore Sports SchoolIBDP option alongside its sports pathways
Madrasah Aljunied Al-IslamiahIBDP alongside Islamic studies
International schoolsSJI International, ACS (International), Hwa Chong International, UWCSEA and ~25 others — private fees (≈S$25k–55k+/yr vs ≈S$15k–20k at the independent schools above)

What you actually study: 6 subjects + the core

One subject from each group — 3 taken at Higher Level (HL, deeper), 3 at Standard Level (SL). Breadth is compulsory: everyone keeps a language, a humanities, a science and maths to the end.

1 · Language & Literature
e.g. English Lit
2 · Language Acquisition
e.g. Chinese B, Spanish
3 · Individuals & Societies
Economics, History, Geography…
4 · Sciences
Physics, Chemistry, Biology…
5 · Mathematics
Analysis & Approaches / Applications
6 · Arts (or a 2nd pick from groups 1–4)
Visual Arts, Theatre, Music…
Theory of Knowledge (TOK)
essay + exhibition on how we know things
Extended Essay (EE)
a 4,000-word independent research paper
CAS
Creativity, Activity, Service — logged over 2 years (required, not scored)

How it is scored — and note: higher is better here

The opposite direction from every Singapore aggregate (PSLE, L1R4, ELR2B2). Coursework done during the 2 years counts alongside the final exams.

6 subjects × up to 7 points= 42 + TOK + EE bonusup to 3 = 45 max
45
perfect — SG has historically produced about half the world’s perfect scorers
40+
excellent — competitive for top universities worldwide
≈38
the Singapore November-session average
≈29
the global average
24
minimum to be awarded the diploma (plus subject-level conditions)

Exams run in November for the Singapore-side schools; results arrive mid-December–January, in time for university applications. Grading is criterion-referenced (like the SEC): 7s are awarded against standards, not a fixed quota.

IB vs A-Levels — the honest comparison

IB DiplomaA-Levels (JC/MI)
ShapeBroad: 6 subjects + TOK/EE/CAS — everyone keeps maths, sciences, languages, humanitiesDeep: typically 3 H2 + 1 H1 content subjects — specialise early (science vs arts stream)
AssessmentCoursework/orals/internal assessment (~20–30% per subject) + final examsMostly final national exams (with project work)
Workload styleContinuous deadlines across 2 years — rewards steady self-managersBack-loaded — rewards strong exam performers
ScoreOut of 45, higher = betterGrades A–E per subject → rank points for university admission
UniversitiesAccepted by NUS/NTU/SMU and strongly recognised overseasEqually accepted locally; well recognised overseas

Neither is “easier” — they filter for different students. A kid who hates spreading thin but crushes exams fits A-Levels; a consistent all-rounder who likes writing and projects fits IB.
