Full SBB After PSLE Results: Subject Levels in Secondary 1

Under Full Subject-Based Banding (Full SBB), your child's PSLE score decides their Posting Group, and the Posting Group sets the starting level for most subjects in Secondary 1: G3 for Posting Group 3, G2 for Posting Group 2 and G1 for Posting Group 1. But the total is not the whole story. Each of English, Mother Tongue, Mathematics and Science can start at a higher level if your child did well enough in that subject, typically with an Achievement Level (AL) of 5 or better.

PSLE results are due tentatively on Tuesday, 24 or Wednesday, 25 November 2026. This guide shows how to read the subject ALs on the results slip, works through three fictional children, and explains what MOE has said in Parliament since August about moving up a level later.

How does the PSLE score set Secondary 1 subject levels?

MOE's posting groups page says Posting Groups are used for secondary school posting and "to guide the initial subject levels your child can take at the start of Secondary 1". Students posted through Posting Group 3 take all subjects at G3, the most demanding level; those in Groups 2 and 1 take most subjects at G2 and G1.

Once in school, students from different Posting Groups share mixed form classes. MOE's Full SBB FAQ says they spend about a third of curriculum time together on common subjects: Art, Character and Citizenship Education, Design and Technology, Food and Consumer Education, Music and Physical Education. The other subjects are taken at each student's own level.

When can my child take a subject at a higher level?

MOE's Full SBB secondary school experience page gives the eligibility rule for English, Mother Tongue, Mathematics and Science at the start of Secondary 1:

• Most subjects at G2 (Posting Group 2): a Standard-level AL5 or better in the subject means the option to take it at G3.
• Most subjects at G1 (Posting Group 1): AL5 or better means the option of G2 or G3; AL6, or grade A at Foundation level, means the option of G2.

The FAQ gives MOE's own example: a student with a PSLE score of 23 and AL5 in Mathematics enters through Posting Group 2, takes most subjects at G2, and can take Mathematics at G3 from the start. It also says a student taking most subjects at G3 who sat English, Mathematics or Science at Foundation level may take those subjects at a less demanding level, in consultation with the school.

From Secondary 2, Geography, History and Literature in English can also be taken at a more demanding level, based on aptitude and interest shown in Secondary 1.

What does this look like for three children?

These children are fictional; the rules applied are MOE's. A PSLE score is the sum of the four subject ALs, as our PSLE score calculator shows.

• Nur, ALs 5 (English), 6 (Mother Tongue), 5 (Mathematics), 7 (Science): score 23, Posting Group 2. Most subjects at G2. English and Mathematics, each AL5, can start at G3. Mother Tongue (AL6) and Science (AL7) stay at G2.
• Jun Hao, ALs 7, 6, 6, 7: score 26, Posting Group 1, because he has AL7 or better in English and Mathematics. Most subjects at G1. Mother Tongue and Mathematics, each AL6, can start at G2. English and Science, each AL7, stay at G1.
• Kavya, ALs 2, 1, 3, 3: score 9, Posting Group 3. All subjects at G3, and her AL1 in Mother Tongue means she may take Higher Mother Tongue from the start.

The lesson for results day: write down all four ALs, not just the total. Two children with the same score can start Secondary 1 with quite different timetables.

Can my child move up a level later?

Yes, but it is the school's decision, not an automatic right. In a 5 August 2026 parliamentary reply, MOE said that after the start of Secondary 1, students may take subjects at a more demanding level based on "a holistic consideration of their performance, interests and readiness". MOE gives schools guidelines, such as subject-specific academic criteria, but schools make the final decision.

Asked on 7 October 2026 whether schools should publish criteria and let students who meet them move up automatically, MOE replied that there are no such plans, because schools weigh each student's interests, aptitude and ability to manage the overall load. Our suggestion: at the start of Secondary 1, ask the school how it decides level changes and when the reviews happen.

Does the Posting Group limit later options?

MOE says it should not. The FAQ states that eligibility for post-secondary routes depends on the subjects and subject levels a student takes, not on the Posting Group they entered through. Its example: a Posting Group 2 student who builds up enough G3 subjects can qualify for junior college on the aggregate score plus the subject grade requirements. The FAQ still quotes today's bar, an L1R5 of 20 or better, but MOE's secondary school experience page says the junior college criterion moves to an L1R4 of 16 or better from 2028, years before today's Primary 6 pupils finish secondary school.

Two related changes: from the 2027 graduating cohort, students sit the new Singapore-Cambridge Secondary Education Certificate (SEC) at their subject levels, and from 2028 a single Post-Secondary Admissions Exercise replaces the Joint Admissions Exercise. Our O-Level results and JAE 2027 guide covers the final O-Level year. Note that schools offering the Integrated Programme, as well as Crest and Spectra Secondary Schools, do not use Full SBB, according to MOE's Full SBB explainer.

A results-day checklist

Our checklist for 24 or 25 November:

1. Copy all four subject ALs onto your shortlist, not only the PSLE score.
2. Mark which subjects can start a level higher using the rule above.
3. Check each shortlisted school's subject offerings on SchoolFinder, especially if Higher Mother Tongue or a third language matters to you.
4. Submit choices within the 7-day window, which closes at 4.30pm on the last day; the dates are in our PSLE 2026 results and S1 posting timeline.
5. Keep the results slip to hand for when your child's new school explains subject levels.
