Three students in school uniforms work through open books at a classroom table, with textbooks and stationery nearby and study notes on the whiteboard behind them.

Where Can I Find Information About Changing G1, G2 and G3 Subject Levels?

Start with MOE’s Full Subject-Based Banding secondary-school guide, then check your child’s school subject-combination information and speak to the relevant teacher. MOE explains the national framework; the school confirms which subjects and levels it offers and how a change is considered.

For examination planning, use the SEAB Singapore-Cambridge Secondary Education Certificate page for the SEC from 2027. If the student sits a 2026 GCE examination, use that examination’s current SEAB page instead of applying future SEC information early.

Check the label carefully: Posting Group 1, 2 or 3 is the route used for secondary-school admission, while G1, G2 and G3 describe the level of an individual subject. A student’s Posting Group does not mean every subject must stay at one matching level.

Which source should we use?

Which assessment applies?SEAB SEC or the current GCE pageCohort, subject and examination documents

Under Full SBB, students may take subjects at G1, G2 or G3 according to their strengths, interests and learning needs. That flexibility does not mean every subject exists at every level in every school. School offerings, timetable fit, readiness and the student’s progress all matter.

What should we check before requesting a change?

Ask which evidence the school considers, what work the student must be ready for, and whether the proposed move is to a more or less demanding level. Also ask how the change affects the timetable, future subject prerequisites, assessment route and the next review point. A clear decision includes both the academic reason and the practical consequences.

Did you know? “Changing level” can sound like a verdict, but it is better understood as a learning-placement decision for one subject at one point in time. The useful question is: which level gives the student an appropriate challenge while keeping the foundations secure?

Keep the cohort straight. Full SBB is already the current secondary-school learning structure, while the SEC is first implemented in 2027. Students sitting 2026 GCE O- or N-Level examinations still need the 2026 rules, syllabuses and administrative instructions for those examinations.

What is the next useful step?

  1. Identify the exact subject, current level and requested level.
  2. Read the school’s latest subject-combination or progression guidance.
  3. Bring recent assessments and learning observations to the teacher discussion.
  4. Confirm the decision, effective date, support plan and review date in writing.

For a fuller explanation, read eduKate’s guides to G1, G2 and G3 subject levels, Full Subject-Based Banding, secondary-school subject combinations and the Singapore school pathways collection.

Choose the question that brought you here. Open one useful guide, try a small task, and stop when you have what you need.

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.
