2026 Is the Last O-Level Ever:
What the New SEC Means for Your Child
From 2027, every graduating Secondary school cohort sits one combined examination instead of three separate ones, and receives a single certificate for it. Here is exactly what changes, what doesn't, and what it means depending on your child's level today.
2026 is Singapore's final GCE O-Level (and N-Level) cohort. From 2027, graduating secondary students will instead receive the Singapore-Cambridge Secondary Education Certificate (SEC) — one national certificate reflecting Full Subject-Based Banding, where each subject is recorded at the level it was taken: G1, G2 or G3[1].
Nothing about this changes the value of a certificate your child already holds or is about to earn in 2026 — MOE and SEAB have confirmed there is no change to the recognised standard of the qualification[1]. What changes is the certificate name, how subjects are recorded, and a few exam-logistics details covered below.
Everything a Sec 1–4 parent needs to know about the SEC switch
- 1.The graduating Sec 4 cohort of 2026 sits the last-ever O-Level and N-Level papers. From 2027, graduating students sit the SEC instead[1].
- 2.The SEC combines 3 separate examinations (O-Level, N(A)-Level, N(T)-Level) into 1 unified certificate, recording each subject at level G1, G2 or G3[1].
- 3.No change in overall exam standards — a certificate your child already holds, or is about to earn, stays fully recognised locally and internationally[1].
- 4.Mother Tongue Language exams simplify to one written sitting a year per level, in September alongside English Language — the final O-Level MTL cohorts have a mid-year sitting plus a year-end sitting; N-Level MTL already has one[1].
- 5.The first SEC cohort (2027) gets results in mid-January 2028, then applies to JC, Millennia Institute, polytechnics or ITE through a new 6-day Post-Secondary Admissions Exercise (PSE)[3].
From Full SBB to your child's SEC certificate
The SEC didn't appear overnight — it is the exam-certification piece of a transition MOE has been rolling out in secondary schools since 2020.
2020–2024
•Full SBB Rollout
Full Subject-Based Banding (Full SBB) rolled out
MOE piloted Full SBB in secondary schools from 2020, expanding it nationwide so students take each subject at the level — G1, G2 or G3 — that matches their strengths, instead of being locked into the Express, Normal (Academic) or Normal (Technical) stream.
2026
•Sec 4 / Sec 5 Cohort
Final O-Level and N-Level examinations
Students graduating from Secondary 4 (or the Normal course) in 2026 sit the very last GCE O-Level and N-Level examinations. Their certificates remain fully valid — no change to the recognised standard of the qualification.
2027
•Sec 4 Cohort
First Singapore-Cambridge SEC examinations
The first SEC cohort sits their exams: English Language and Mother Tongue Language written papers in September, all other subjects from October to November, with oral, listening and practical components completed earlier.
Jan–Feb 2028
•Results Day + PSE
SEC results and the new Post-Secondary Admissions Exercise
SEC results release mid-January 2028. A 6-day Post-Secondary Admissions Exercise (PSE) opens immediately for JC, Millennia Institute, polytechnic and ITE applications, with posting outcomes by early-February and acceptance due end-February 2028.

O-Level / N-Level vs the new SEC
Most of what your child experiences in the classroom doesn't change. The differences are in certification, exam logistics and the post-secondary application process.
| Aspect | Until 2026 (O-Level / N-Level) | From 2027 (SEC) |
|---|---|---|
| National examinations | Separate GCE O-Level, N(A)-Level and N(T)-Level examinations — the graduating cohorts of 2026 sit them for the last time | One combined examination: the Singapore-Cambridge SEC |
| Certificate received | Separate certification depending on the examination taken — O-Level or N-Level | A single SEC certificate listing every subject at the level it was taken — G1, G2 or G3 |
| Subject levels in school | Already G1, G2 or G3 for every student since the 2024 Sec 1 cohort under Full SBB — streams no longer exist in Sec 1–3 today | Unchanged — the SEC simply certifies the same G1, G2 or G3 subjects under one name |
| Grading scale | Final O-Level cohorts: A1–F9 · N(A)-Level: 1–6 · N(T)-Level: A–E | Same familiar scales, mapped to subject level: G3 A1–F9 · G2 1–6 · G1 A–E |
| Awarding bodies | SEAB, MOE & Cambridge International Education, UK | Unchanged — SEAB, MOE & Cambridge International Education, UK |
| Mother Tongue Language exam sittings | Two sittings for the final O-Level MTL cohorts (mid-year + year-end); one sitting for N-Level MTL | One sitting for every subject level, in September alongside English Language |
| Results release | Split dates — N-Level mid-December, O-Level mid-January | One January release for every subject level |
| Applying to JC / MI / Poly / ITE | Joint Admissions Exercise (JAE) after O-Level results | New Post-Secondary Admissions Exercise (PSE) starts 2028: 6-day online window on the Post-Sec Portal, opening the day SEC results are released |

Grading isn't getting harder or easier
G1, G2 and G3 grading bands are calibrated to what N(T)-Level, N(A)-Level and O-Level grades meant respectively — a G3 A1 is the same bar as today's O-Level A1[1].
There is no change in the overall standards of examinations under the SEC, and the qualification continues to be recognised locally and internationally.
What it means depending on your child's level in 2026
The transition lands differently depending on where your child is right now. Here's the practical read for each level, assuming the standard 4-year Express track.
Secondary 4 in 2026
Sits the very last O-Level or N-Level papers this year. Nothing changes for your child — same exam format, same certificate, same recognition.
Secondary 3 in 2026
Becomes the first-ever SEC cohort, sitting the new exam in October–November 2027 and receiving results in January 2028.
Secondary 2 in 2026
The second SEC cohort — graduates in 2028, a year after the new system has already run once.
Secondary 1 in 2026
Spends all four years of secondary school under Full SBB and the SEC system from day one — never experiences the O-Level/N-Level system at all.
The certificate name changes. What matters doesn't.
for SG parents navigating the SEC transition
A different certificate name isn't a different bar. What your child needs is still strong fundamentals across every subject — not a new exam to fear.
Whether your child sits the O-Level in 2026 or the SEC from 2027, the syllabus, teaching and school life stay the same. Keep learning the way you always have.
Track your child's exact cohort against the timeline above, and don't confuse a rename with a harder bar — MOE has confirmed the standard hasn't moved.

Frequently asked questions
Will my child's existing GCE O-Level or N-Level certificate still be recognised after 2026?
Yes. SEAB and MOE have confirmed there is no change in the overall standards of the examination, and certificates already issued continue to be recognised locally and internationally, exactly as before.
What exactly is the Singapore-Cambridge Secondary Education Certificate (SEC)?
The SEC is a single national certificate that combines the separate GCE N(T)-Level, N(A)-Level and O-Level examinations into one certification from 2027. It is jointly examined and awarded by SEAB, MOE and Cambridge International Education, UK, and records each subject at the level it was taken — G1, G2 or G3.
Which of my child's cohort is affected first?
The graduating Secondary 4 (and equivalent Secondary 5 Normal course) cohort of 2026 will be the last to sit GCE O-Level or N-Level papers. Students who reach Secondary 4 in 2027 onward will sit the SEC instead.
Does the SEC change my child's chances of getting into a Junior College?
The SEC itself is a certification change, not a harder or easier exam. Separately, MOE has already announced that JC admission moves from L1R5 to L1R4 from the 2028 intake onward — the same cohort that sits the first SEC exams in 2027. See our full L1R4 breakdown for the admission-criteria details.
What's changing with Mother Tongue Language (MTL) exams under the SEC?
For the final O-Level cohorts, MTL papers involve a mid-year sitting in addition to the year-end paper; N-Level MTL has just one sitting. Under the SEC, there will be only one written examination sitting each year for every MTL subject level — G1, G2, G3 MTL and G3 Higher MTL — held in September alongside the English Language written examinations.
When will the first SEC cohort get their results, and what happens next?
The 2027 SEC cohort receives results in mid-January 2028. A 6-day online Post-Secondary Admissions Exercise (PSE) opens immediately after results, letting students apply via the Post-Sec Portal (with Singpass) to JCs, Millennia Institute, polytechnics or ITE. Posting outcomes are released by early-February 2028, with acceptance due by end-February 2028.
