G1 and the SEC: What Changes from the Old N(T)-Level System?

G1 is broadly mapped from the standard of the former Normal (Technical), or N(T), subjects. However, G1 should not be treated as simply the old N(T)-Level system with a new name. Full Subject-Based Banding has changed how students take subjects: a learner can study different subjects at G1, G2 or G3 according to strengths, interests and learning needs. From 2027, the national N(T)-, N(A)- and O-Level examinations are replaced by the Singapore-Cambridge Secondary Education Certificate (SEC), which records the subjects and levels taken.

For parents, the most important difference is that the subject level is no longer a fixed stream identity. A student taking G1 Mathematics may take another subject at G2 or G3, depending on the school’s arrangements and the student’s learning progress. The SEC certificate brings these subjects together. Families should therefore use current G1 syllabus documents and admission rules, not rely exclusively on older N(T)-Level books, course descriptions or assumptions about post-secondary routes.

1. What G1 means today

G stands for General. G1, G2 and G3 are the subject levels used under Full SBB. They are broadly mapped from the former N(T), N(A) and Express standards respectively. The mapping helps families understand the relative level of demand, but it should not be used as a complete description of the curriculum, student or future opportunities.

In Full SBB, students are placed in mixed form classes and take subjects at the levels that suit their strengths, interests and learning needs. Students may take a mix of G1, G2 and G3 subjects. They attend subject lessons with peers taking the same level for those subjects, while the common curriculum provides opportunities for students from different subject levels to learn together.

This is why it is not accurate to say that a child is “in the N(T) stream” as a current formal identity. The student has a subject combination. Parents should read each subject’s level separately and ask how the school supports the learner’s progress.

2. What changes with the SEC in 2027?

SEAB states that from 2027, the Singapore-Cambridge GCE N(T)-, N(A)- and O-Level examinations will be combined and renamed the Singapore-Cambridge Secondary Education Certificate. The examination continues to be jointly examined and awarded by SEAB, MOE and Cambridge International Education. Students sit subjects at their respective G1, G2 or G3 levels, and their certificate records the subjects and subject levels taken.

The SEC does not mean that all students sit the same paper for every subject. The subject level determines the syllabus and assessment standard. G1 English is not the same paper as G2 or G3 English. A candidate’s certificate may contain subjects at more than one level. This reflects the subject-based nature of the system.

SEAB states that there is no change in the overall examination standards under the SEC and that the qualification continues to be recognised locally and internationally. The new certificate is a combined national framework, not a statement that every subject has the same content or that the old course rules carry over unchanged.

3. What remains familiar?

There are important continuities. G1 standards are broadly aligned to the former N(T)-Level standard. G1 uses the A-to-E grading structure associated with the former N(T)-Level examination. The assessment mode and overall examination standards remain aligned to the corresponding former examination levels, according to SEAB’s SEC information.

Students still need to learn the subject content, practise the relevant skills and meet the examination requirements. A new certificate name does not remove the need for careful preparation. The student must still understand the actual syllabus, complete any relevant practical or coursework components and follow the official examination instructions.

4. What parents should stop assuming from old N(T)-Level information

Older resources may use old subject codes, old certificate names, old examination calendars and historical admissions rules. Some content may remain helpful, but parents should check whether it is still valid for the current SEC cohort. The 2027 G1 directory uses K-series codes such as K100 for English, K110 for Mathematics and K123 for Science. Older course codes may appear as references to earlier syllabuses.

Do not assume that an old N(T)-Level admission table still describes the route available to a student taking the SEC. MOE has announced a new Post-Secondary Admissions Exercise for 2028, as well as specific changes to JC and polytechnic admission calculations. Check the current course requirements for the cohort applying rather than rely on a guide written for a previous system.

Do not assume that the student is permanently fixed at G1 in every subject. Full SBB allows subject-level flexibility at appropriate junctures. The school manages the actual review process and the availability of its courses. A parent should discuss readiness with the subject teacher instead of treating a single score as an automatic change.

5. How the G1 grading structure works

SEAB states that G1 subjects use grades A, B, C, D and E. G2 subjects use grades 1 to 6, while G3 subjects use the A1 to 9 grading structure. These are separate scales. Grade A at G1 and Grade 1 at G2 should not be treated as identical raw marks.

SEAB publishes grade-mapping tables for cases where subject grades at different levels must be used to compute a particular aggregate score or progression rule. The mapping applies for the stated purpose; it does not change the original grade on the certificate. Parents should use the official computation for the named admission route.

6. What a parent should do with old textbooks and past papers

Check the code and year before using a resource. If the older paper covers a concept that remains in the new syllabus, it may be useful for practice. If the paper uses an assessment format or topic that has changed, it may be unsuitable as a full examination simulation. The current syllabus must take priority.

Make a note on older materials: historical reference, current topic match, or not aligned. This helps the student avoid wasting time on a complete old paper that does not match the current SEC. Teachers can often identify which questions remain suitable for strengthening the concept.

7. How subject levels can shape a learner’s pathway

Full SBB recognises that learners have different strengths in different subjects. A child may need a more supportive level in one subject while being ready for greater challenge in another. This can create a more appropriate programme and help the student build confidence, competence and a realistic route into further education.

However, subject-level flexibility does not guarantee entry to every post-secondary course. Each pathway has official subject, grade and aggregate requirements. Parents should check the current admission rules and ask the school which subject combinations may support the student’s interests. A G1 student can still have purposeful learning goals and meaningful progression options.

8. Questions parents can ask

Frequently asked questions

Is G1 exactly the same as N(T)-Level?

G1 is broadly mapped from the former N(T)-Level standard. It operates within Full SBB, where subject levels can vary across a student’s subject combination.

Will students still receive separate N(T), N(A) and O-Level certificates in 2027?

No. From 2027, the national examination is the SEC, with one certificate reflecting the subjects and levels taken.

Do all G1 subjects use the same examination paper?

No. Each subject has its own syllabus and assessment format, and G1 papers are distinct from G2 and G3 papers.

Can my child move from G1 to G2?

Subject-level adjustments may be considered at appropriate junctures according to learning progress and school arrangements. It is not automatic or guaranteed.

Can we continue using old N(T)-Level practice papers?

Selected questions may be useful if they match the current syllabus. Check the current subject code, content and assessment format first.

Official references and related eduKate reading

Read the SEAB SEC overview, the 2027 G1 school-candidate syllabus directory and MOE’s Full Subject-Based Banding information. For a practical illustration of diagnosing and rebuilding subject understanding, see the Clementi Mathematics teaching reference.

The best way to understand G1 is to see it as one part of a student’s subject-based learning programme. The former N(T)-Level comparison offers historical context, but the current decisions should be made using Full SBB, the SEC syllabus and the student’s actual school arrangements.

Take one question further

The same learning habit can travel across subjects, while each subject keeps its own methods. These routes help you notice a difficulty, understand one part of it, and return to something you can do.

A word is familiar, but using it is difficult.

Move from recognising a word to retrieving it in a new context. Understand vocabulary plateaus.

Try it without the guide: Choose one word you already know. Close the guide and use it in a new sentence. Explain why it fits; try another context tomorrow.

A piece of writing has ideas, but the reader loses the thread.

Make the order of events and the links between sentences clear. Explore composition writing.

Try it without the guide: Choose one short paragraph. Read the relevant explanation, close it, and revise the paragraph. Ask someone to tell you what happened and why.

The Mathematics seems familiar, but marks still disappear.

Find the first point where the working stops being reliable. Find Secondary 4 A-Math mark leakage.

Try it without the guide: For a Secondary 4 A-Math question you have attempted, locate the first uncertain line. Repair that step, then try a comparable question without the worked answer.

A Science fact is remembered, but the explanation is incomplete.

Connect the evidence to a scientific idea and the resulting change. Follow the Primary Science learning route.

Try it without the guide: Choose a familiar Primary Science example. Explain the evidence, the idea and the result without notes. Then change one condition and explain your prediction.

Two accounts of the world seem to disagree.

Check the question, source, date and evidence before combining claims. Explore the World Knowledge research library.

Try it without the guide: Take one claim. Find the source best placed to support it, note its date, and state what remains uncertain. Return to your original question.

There is plenty of help, but independence is hard to see.

Check what the learner can understand and do after support is removed. Understand how education works.

Try it without the guide: Choose one small task the child has practised. Agree on a calm, brief attempt without prompts. Use what happens to choose one next step, then stop.
