A PSLE Foundation subject is graded AL A, AL B or AL C instead of AL1 to AL8, and for Secondary 1 posting Ministry of Education (MOE) counts those grades as AL 6, AL 7 and AL 8 respectively — so a Foundation subject adds between 6 and 8 points to the PSLE Score. Ancourage Academy teaches Primary 5 and Primary 6 students at its Bishan and Woodlands centres, and parents of Foundation students tend to ask three things: what the grades mean, how they change the PSLE Score, and what they do to secondary school options. For the wider scoring picture, start with our PSLE scoring system guide; for subject support, see our primary tuition programmes.
Ancourage Academy's P5 Mathematics classes run in small groups of 3 to 6; book a trial class (usually $18) to start with a diagnostic of where your child stands.
What Are PSLE Foundation Subjects and How Are They Graded?
Foundation is the second of two levels at which a PSLE subject can be taken, and it has its own three-grade scale: AL A, AL B and AL C.
MOE states it plainly on its PSLE scoring system page: "Under the new AL system, if your child is taking Foundation level subjects, your child will be graded AL A to AL C." Like the Standard Achievement Levels, the Foundation grades describe what a child has achieved against the curriculum, not how they ranked against other candidates.
The four subjects that can be taken at either level are English Language, Mathematics, Science and Mother Tongue Language. Our glossary entry on PSLE Foundation and Standard levels gives the short definition; the rest of this guide deals with what the grades do.
MOE's PSLE FAQs note: "With just three AL bands for Foundation subjects, the percentage score range for each AL will naturally be wide." That width shapes preparation.
Who Takes Foundation Subjects, and When Is the Decision Made?
The decision is made at the end of Primary 4, under subject-based banding: the school recommends a combination from the P4 examination results, parents indicate a preference on an option form, and the combination can be adjusted again at the end of Primary 5.
MOE's subject-based banding page for primary schools sets out the sequence year by year:
- Primary 4. The "School recommends a subject combination based on their exam results at the end of the year", and "You will need to fill up an option form to indicate your child's preferred subject combination."
- Primary 5. The child takes the chosen combination. The "School assesses your child's ability to cope with the subjects at the end of the year", and "Adjustments to the subject levels are made if needed."
- Primary 6. The child "takes the subject combination recommended by the school and sits for the Primary School Leaving Examination (PSLE)."
Who is offered the choice is also defined. According to the same page, a child who passes three or more subjects in Primary 4 is offered the four Standard subjects, while "Students who pass 2 subjects or less will be offered the following choices": four Standard subjects, three Standard and one Foundation, two and two, one Standard and three Foundation, or four Foundation subjects. MOE adds: "Taking subjects at the foundation level is not a disadvantage for your child."
The P4 decision is not final — the end-of-P5 review is a second checkpoint — and the choice is subject by subject, so a child can keep English at Standard while taking Mathematics at Foundation.
How Do AL A, AL B and AL C Count Towards the PSLE Score?
For Secondary 1 posting, AL A counts as AL 6, AL B as AL 7 and AL C as AL 8, and the PSLE Score is still the sum of four subject ALs, from 4 to 32.
MOE's wording is precise: "For the purpose of S1 posting, Foundation level AL A to AL C will be mapped to AL 6 to AL 8 of Standard level subjects respectively, to derive a student's overall PSLE Score." The mark bands behind each grade are published on the same MOE scoring page, alongside the Standard bands they map to:
| Foundation grade | Foundation mark range | Counts in the PSLE Score as | Standard mark range for that AL |
|---|---|---|---|
| AL A | 75–100% | AL 6 | 45–64% |
| AL B | 30–74% | AL 7 | 20–44% |
| AL C | Below 30% | AL 8 | Below 20% |
Two consequences are worth writing down before looking at examples. A Foundation subject can never contribute fewer than 6 points, because AL A is the best Foundation grade and it maps to AL 6. And a child taking all four subjects at Foundation level will have a PSLE Score between 24 and 32 — four AL As make 24, four AL Cs make 32. Our PSLE Score calculator takes each subject's raw mark out of 100; switch a subject to Foundation and it applies the AL A, B or C grade and its AL 6, 7 or 8 equivalent for you.
Worked Examples: Scoring a Mixed Standard and Foundation Profile
Add the four ALs exactly as you would for Standard subjects, after replacing each Foundation grade with its mapped AL — the three profiles below land in three different Posting Groups.
The Posting Group bands come from MOE's Posting Groups page: a PSLE Score of 4–20 is Posting Group 3; 21 and 22 is Posting Group 2 or 3; 23 and 24 is Posting Group 2; 25 is Posting Group 1 or 2; and 26–30 is Posting Group 1 "with AL7 or better in English Language and Mathematics".
| Profile | English | Mathematics | Science | Mother Tongue | PSLE Score | Posting Group |
|---|---|---|---|---|---|---|
| A — one Foundation subject | AL 4 | Foundation AL A (6) | AL 5 | AL 3 | 4 + 6 + 5 + 3 = 18 | 3 |
| B — two Foundation subjects | AL 6 | Foundation AL B (7) | Foundation AL A (6) | AL 5 | 6 + 7 + 6 + 5 = 24 | 2 |
| C — two Foundation subjects | AL 7 | AL 7 | Foundation AL B (7) | Foundation AL A (6) | 7 + 7 + 7 + 6 = 27 | 1 |
- Profile A scores 18, inside the 4–20 band, so the child is posted through Posting Group 3 despite taking Mathematics at Foundation level.
- Profile B scores 24, inside the 23–24 band, so the child is posted through Posting Group 2. Raising Foundation Mathematics to AL A would give 23 — still Posting Group 2.
- Profile C scores 27, inside the 26–30 band, and meets MOE's stated condition with AL 7 in both Standard English and Standard Mathematics, so the child is posted through Posting Group 1.
One case the tables do not settle: when English or Mathematics is itself a Foundation subject and the score falls in the 26–30 band, MOE's pages, as of September 2026, do not spell out how the Foundation grade is read against the "AL7 or better in English Language and Mathematics" condition. Ask the primary school for a written answer for your child's exact profile rather than relying on the mapping alone.
Can a Child Taking Foundation Subjects Still Reach Posting Group 3?
Yes — MOE says a child can qualify for Posting Group 3 or 2 while taking one or more Foundation subjects, because the Posting Group follows the PSLE Score, not the level at which each subject was taken.
The MOE PSLE FAQs put it directly: "It is possible for students to qualify for Posting Group 3 or 2 even if they take one or more subjects at the Foundation level." The same answer adds that "Students should thus decide whether to take a subject at Standard or Foundation level based on their aptitude and ability to cope with the demands of that particular subject."
The arithmetic sets the limits. With one Foundation subject, the best possible PSLE Score is 9 (AL 1 in the three Standard subjects plus 6), comfortably inside Posting Group 3. With four Foundation subjects, the best possible score is 24, which is Posting Group 2. Where the posting group then leads, school by school, is covered in our guide to choosing a secondary school and in our secondary school cut-off points table.
Which Subject Levels Can a Foundation Student Take in Secondary 1?
Under Full Subject-Based Banding, an AL A in a Foundation subject lets a student posted through Posting Group 1 take that subject at G2 instead of G1, and a Posting Group 3 student who took English, Mathematics or Science at Foundation may choose G2 for that subject.
Under Full SBB, the Posting Group sets the indicative level for most subjects — G3 for Posting Group 3, G2 for Posting Group 2, G1 for Posting Group 1 — and individual PSLE subject grades can move a subject up or down. MOE's Full SBB secondary school experience page sets out the eligibility for English Language, Mother Tongue Languages, Mathematics and Science at the start of Secondary 1:
| Indicative level of most subjects | PSLE Standard grade | PSLE Foundation grade | Option to take that subject at |
|---|---|---|---|
| G2 (Posting Group 2) | AL 5 or better | — | G3 |
| G1 (Posting Group 1) | AL 5 or better | — | G2 or G3 |
| G1 (Posting Group 1) | AL 6 | AL A | G2 |
Read the dashes carefully: in MOE's table no Foundation grade gives a Posting Group 2 student the option of G3 in that subject at the start of Secondary 1. Applied to the worked profiles, Profile C (a Posting Group 1 profile with Foundation AL A in Mother Tongue and Foundation AL B in Science) gains the option of G2 Mother Tongue, while its Foundation AL B in Science does not change Science's level.
The same MOE page runs the other way for Posting Group 3 students: "For students who offered English, Mathematics and/or Science at Foundation level at PSLE, but are otherwise eligible to take most of their subjects at G3 when entering secondary school, they may choose to take these subjects at a less demanding level (i.e., G2), in consultation with their secondary schools." For Profile A, that means Mathematics can start at G2 or G3 — a real choice, discussed in our G1, G2 and G3 Mathematics guide. Mother Tongue has its own rule on that page, for students who "face exceptional difficulties coping with their Mother Tongue Languages": in a Posting Group 3 profile, Foundation MTL at AL A gives the option of G2, and AL B or C gives G1 or G2.
None of this is permanent. MOE notes that students "may also offer the subjects above at a more demanding level based on their performance in secondary school", which our G2 vs G3 subject levels guide and Full SBB parent guide explain. The logic behind the AL A row is stated in MOE's PSLE FAQs: "students who score AL A for a Foundation subject would have demonstrated the ability to cope with the subject’s G2 curriculum in secondary school."
How Should a P5 or P6 Foundation Student Prepare?
Treat 30% and 75% as the only two marks that change a Foundation grade, and put Foundation effort into moving across the 75% line — while remembering that one AL point in a Standard subject is worth exactly as much.
Because AL B runs from 30% to 74%, a Foundation mark rising from 45% to 70% does not change the PSLE Score at all. That is not a reason to stop, but it is a reason to plan with the thresholds in view. A sensible sequence for a P5 or P6 child:
- Get the school's marks, not just the grade. From P5, MOE reports school examination results in ALs; ask the teacher for the percentage too, so you know whether the child sits at 40% or 70% within AL B.
- Secure the fundamentals first. Foundation subjects exist, in MOE's words, so students can focus "on building up strong fundamentals". In Mathematics that means accurate number work and clear working; our bar model guide covers the method most word problems rely on.
- Compare the one-point gains. A Standard subject moving from AL 6 to AL 5 (from below 65% to 65% or above) and a Foundation subject moving from AL B to AL A are each worth one point. Put effort where the next point is nearest.
- Revisit the level at the end of P5. If a child is comfortably above 75% in a Foundation subject, raise the Standard-level question with the school at the P5 review.
- Revise all four subjects in one plan. Our PSLE revision guide sets out a subject-by-subject timetable, and our guide to what changes in Sec 1 Maths shows what comes next.
Ancourage Academy's P5 Mathematics, P6 Mathematics, P6 English and P6 Chinese classes run in small groups, so a Foundation student works on their own gaps rather than the pace of the room. A trial class (usually $18) starts with a diagnostic.
Questions to Ask the Primary School
The school, not a general guide, holds the facts that decide your child's case — the current marks, the P5 review timing and how the Posting Group rules apply to their exact profile.
- Which subjects does the school recommend at Foundation level, and on which P4 or P5 results?
- When is the end-of-P5 review, and what mark would the school want to see before moving a subject back to Standard?
- If English or Mathematics is taken at Foundation, how does that grade apply to the Posting Group 1 condition for a score of 26–30?
- Which secondary subject levels would my child's projected PSLE grades open at the start of Secondary 1?

Common Questions About PSLE Foundation Subjects
What is AL A in PSLE Foundation?
AL A is the best of the three Foundation grades, awarded for a Foundation mark of 75% to 100%. For Secondary 1 posting, MOE maps AL A to AL 6, so it adds six points to the PSLE Score. MOE also treats AL A as showing that a child can cope with that subject's G2 curriculum in secondary school.
How is a Foundation subject counted in the PSLE Score?
Replace the Foundation grade with its mapped AL — AL A as 6, AL B as 7, AL C as 8 — and add it to the other three subject ALs. For example, English AL 4, Science AL 5, Mother Tongue AL 3 and Foundation Mathematics AL A give 4 + 5 + 3 + 6 = 18, which is Posting Group 3.
Is taking Foundation Maths a disadvantage for secondary school?
MOE says taking subjects at Foundation level "is not a disadvantage" and that students can still qualify for Posting Group 3 or 2. The real effect is arithmetic: a Foundation subject contributes at least 6 points to the PSLE Score. A Posting Group 3 student who took Mathematics at Foundation may choose G2 Mathematics in Secondary 1, in consultation with the school.
Can my child switch from Foundation back to Standard level?
Yes, at the scheduled review. Under subject-based banding the school recommends a combination at the end of Primary 4, then assesses at the end of Primary 5 whether the child is coping, and "Adjustments to the subject levels are made if needed." Ask the school what results it would want to see before recommending a return to Standard.
What is the best PSLE Score possible with all four subjects at Foundation?
The best possible score is 24, from AL A in all four subjects (4 × 6), and the lowest is 32 from four AL Cs. A score of 24 falls in MOE's 23–24 band, which is Posting Group 2, where students take most subjects at G2 at the start of Secondary 1.
