Quick answer: 2026 is the last year in which the separate GCE N(T)-Level, N(A)-Level and O-Level qualifications are awarded. From 2027, graduating students sit the Singapore–Cambridge Secondary Education Certificate (SEC) at their registered G1, G2 and G3 subject levels. The first SEC year includes both students who entered Secondary 1 in 2024 under Full Subject-Based Banding and eligible Secondary 5 students from the older 2023 cohort.
That means “SEC 2027” does not mean every candidate entered school under Full SBB. It is one common certificate that records the actual subjects and levels each eligible candidate takes. This guide explains the cohort transition, the last old examinations, the new certificate and what parents should check before making assumptions about results or pathways.

2026 is the last year for separate N(T), N(A) and O-Level awards
SEAB’s published FAQ is clear: 2026 is the last year in which the separate GCE N(T)-, N(A)- and O-Level qualifications will be awarded. From 2027, graduating students sit the SEC examination. This is the national qualification transition associated with Full SBB.
Families sometimes see the old examination names in school documents, old textbooks or advice from older siblings and assume that the same arrangement continues for the 2027 cohort. Historical resources can still be useful when a syllabus has continuity, but the examination-year registration and current subject code must be checked.
Do not tell a student that all GCE content suddenly disappears. The standards and subject content retain continuity with the corresponding former levels. The qualification and timetable are being brought together; the actual learning still follows the relevant G1, G2 or G3 syllabus.
The first SEC cohort includes more than one school-entry cohort
The first SEC examination year is 2027. It includes graduating Full SBB students who entered Secondary 1 in 2024 and, where eligible, students from the preceding 2023 entry cohort who continue to Secondary 5. SEAB specifically names the Secondary 5 students from 2023 in its explanation of the transition.
This is why the phrase “first SEC cohort” can be confusing. The qualification begins in 2027, but not every person receiving it has experienced the same secondary-school structure from Secondary 1. Some students have followed the older N(A) route before progressing to Secondary 5; others have experienced Full SBB from the start of secondary school.
When asking a school about a candidate’s exam route, give the entry cohort, current year, subject level and registered subject combination. A single shorthand such as “2027 cohort” may not be enough to answer a detailed question.
A simple cohort map: 2023 entry versus 2024 entry
| Student’s Secondary 1 entry | Secondary 4 timing | Possible 2027 examination route |
|---|---|---|
| 2023 entry | 2026 | Eligible students may progress to Secondary 5 in 2027 and sit the SEC at their registered subject levels |
| 2024 entry | 2027 | First Full SBB-entry cohort graduates and sits the SEC in 2027 |
| 2025 entry | 2028 | Continues the Full SBB subject-level route and later sits SEC |
This is a broad progression map, not a guarantee that every pupil in a cohort will follow the same number of years. Subject progression, a fifth year, school-specific arrangements and individual circumstances may affect the actual examination year.
The key point is that the SEC qualification is common, while the candidate’s route into it may differ. The certificate records subjects and subject levels rather than presenting one whole-student stream label.
What does one common SEC certificate mean?
SEAB says eligible candidates receive one Singapore–Cambridge SEC certificate showing the subjects and subject levels they offered. A student may have G3 English, G2 Mathematics and another subject at G1 or G2. The certificate is not split into separate N(T), N(A) and O-Level certificates.
One qualification format does not mean one identical examination paper. A student sits the specific subject and level for which they are registered. G1, G2 and G3 retain their respective syllabus content, assessment schemes and grade scales.
Read every result with its subject title and level. An A in a G1 subject is not automatically interchangeable with an A1 in a G3 subject, and an admissions mapping table should only be used for the calculation it was designed to support.
Do G1, G2 and G3 standards change because the certificate is combined?
SEAB states that the overall examination standards and formats remain aligned to the corresponding former N(T)-, N(A)- and O-Level papers. The purpose of consolidation is to make the qualification and timetable fit a system in which students can take different levels across different subjects.
It is therefore misleading to say that G1, G2 and G3 are simply new names for one common difficulty level. The G levels retain distinct subject standards. The certificate is common; the examination requirements for the student’s subjects are not made identical.
For preparation, use the official syllabus for the correct subject code and examination year. An old paper may help with an overlapping concept, but a teacher should check whether the question format and content are still within the current specification.
The major timetable difference in 2027
The SEC timetable is consolidated into one national framework. SEAB states that non-written examination components such as oral, listening comprehension and practical assessments continue to take place before the written examinations. Written English Language and Mother Tongue Language examinations are scheduled in September. Most other written examinations are held in a common period beginning in October.
Results are released in January of the following year. This is different from the older separate GCE result-release patterns, which were not identical across N(A)/N(T) and O-Level routes.
Use the annual timetable for exact dates and times. A month-level overview is not a substitute for the candidate’s personal paper schedule.
What happens to students who are not part of the 2024 Full SBB entry cohort?
Students from earlier cohorts may still be affected by transitional arrangements. The 2023-entry cohort is the clearest example because eligible Secondary 5 pupils sit SEC in 2027 even though their Secondary 1 experience predated Full SBB’s full implementation.
Other individual circumstances—such as changing schools, returning from overseas or taking examinations as a private candidate—must be checked against SEAB’s current candidate rules. Do not infer a candidate’s subject eligibility from the usual progression of a mainstream cohort.
Where a student is no longer registered through a school, SEAB’s private-candidate pathway has its own registration details and subject availability. It is not the same as asking a school to submit a normal school-candidate entry.
How to read old GCE resources without confusing the SEC
Some older learning resources remain relevant because the SEC standards are aligned to former examination levels. However, families should identify the old resource’s subject, level, year, topic and assessment format before using it.
For example, an O-Level Additional Mathematics paper may help practise a concept that remains in G3 Additional Mathematics. It does not automatically reflect the complete 2027 K341 syllabus, paper structure or any new topic emphasis. The same caution applies to N(A) and N(T) resources when preparing for G2 or G1.
Use the latest SEAB syllabus as the source of truth. If an old resource covers material outside the current syllabus, the student may waste time on material that is not required. If it misses a new topic or assessment demand, the student may develop a false sense of readiness.
Will the SEC change post-secondary admissions?
The qualification transition is linked to wider changes in post-secondary admissions from 2028. MOE has announced a new Post-Secondary Admissions Exercise for participating routes, using the SEC results and destination-specific admission criteria.
Families should not assume the 2027 SEC certificate itself guarantees access to a course. Junior colleges, Millennia Institute, polytechnics, PFP and ITE programmes have their own subject prerequisites, aggregate calculations and places. Some routes allow specific G3-to-G2 mappings for an aggregate; that does not change the original certificate result.
When the student receives the actual SEC results, read the current 2028 admissions booklet and the specific institution’s requirements. Do not rely on an older JAE calculator as if the admission structure had not changed.
A parent checklist for the transition
- Confirm the student’s Secondary 1 entry year and current school year.
- Ask whether the candidate is registered as a school candidate or private candidate.
- Write down each subject, G level and SEC code.
- Use the matching 2027 syllabus and examination scheme.
- Check the official personal timetable when released.
- Use the 2028 admissions rules only for the relevant destination and intake.
This short record prevents a common problem: applying a rule intended for the 2024 Full SBB-entry cohort to a student following a transitional route—or the reverse.
Frequently asked questions

Yes. SEAB says 2026 is the last year for the separate N(T), N(A) and O-Level qualifications.
Do all SEC candidates enter Secondary 1 under Full SBB?
No. Eligible Secondary 5 students from the 2023 entry cohort also sit the SEC in 2027.
Does one SEC mean every candidate takes the same papers?
No. Candidates take their registered subjects at the respective G1, G2 or G3 levels.
Does the certificate show the student’s Posting Group?
It reflects the subjects and subject levels offered, not a single whole-student stream label.
Are the G1, G2 and G3 standards made identical?
No. The respective subject standards remain aligned with the corresponding earlier examination levels.
When are SEC results released?
SEAB states that results are released in January of the following year.
