Foundation subjects at PSLE are graded AL A, AL B or AL C, not AL1 to AL8. AL A is the highest Foundation grade and AL C is the lowest. For calculating the overall PSLE Score used in Secondary 1 posting, AL A is mapped to AL6, AL B to AL7 and AL C to AL8.
The current Foundation raw-mark bands are AL A for 75–100, AL B for 30–74 and AL C for below 30. The mapping does not mean a Foundation paper is identical to a Standard paper or that an AL A Foundation mark is the same achievement as a Standard AL6 mark. It is a scoring conversion used when the subject result is added to the child’s other subject scores for posting.
If you need to calculate the total now, write every subject and its reported AL on a separate line. Keep Standard AL1–AL8 as shown; convert each Foundation AL A/B/C to 6/7/8; then add the four subject values. Check the actual result slip and official posting information before making a school decision. The chapters below explain the grade bands, the conversion, worked examples and what the score does—and does not—tell you about G1, G2 and G3 subjects.

1. What are AL A, AL B and AL C in PSLE?
Foundation English Language, Foundation Mathematics, Foundation Science and Foundation Mother Tongue Language use the Foundation Achievement Level scale. Candidates receive AL A, AL B or AL C for the subject. This is a three-band reporting scale, while Standard subjects use AL1 to AL8.
| Foundation grade | Raw-mark range | Position on Foundation scale |
|---|---|---|
| AL A | 75–100 | Highest Foundation Achievement Level |
| AL B | 30–74 | Middle Foundation Achievement Level |
| AL C | Below 30 | Lowest Foundation Achievement Level |
Did you know a wider band can contain many different raw marks? A pupil with 35 and a pupil with 70 are both within AL B. That is why an Achievement Level is not a detailed diagnosis of every skill. It reports the examination outcome within the published band; the child’s scripts, schoolwork and teacher observations are still needed to locate the learning gaps.
Foundation subjects also have their own curriculum and examination specifications. A Foundation Mathematics candidate and a Standard Mathematics candidate do not sit the same subject entry merely because both results later contribute a number to the overall PSLE Score. Keep the curriculum route, the examination grade and the posting conversion as three separate pieces of information.
SEAB’s current FAQ confirms that Foundation English, Mathematics, Science and Mother Tongue candidates receive AL A, B or C. Check the grades shown on a PSLE certificate and the 2026 PSLE formats directory for the applicable subject entry.
2. How are Foundation grades converted for the PSLE Score?
For Secondary 1 posting, the Foundation grades are mapped onto numeric subject values so they can be added to the other PSLE subject scores. AL A maps to 6, AL B maps to 7 and AL C maps to 8. The lower overall PSLE Score remains the stronger result because the subject values are added.
| Reported Foundation grade | Value used in overall PSLE Score | Do not misread it as |
|---|---|---|
| AL A | 6 | The same paper, raw mark or curriculum as Standard AL6 |
| AL B | 7 | A precise statement of every skill between 30 and 74 marks |
| AL C | 8 | A permanent prediction of the child’s secondary-school ceiling |
The Rainbolt move is to locate the number before interpreting it. On the certificate, the Foundation subject is reported as AL A, B or C. In the overall-score calculation, that reported grade contributes 6, 7 or 8. In the secondary school, a later subject-level decision uses the applicable rules and evidence. Those are connected locations, but they are not the same location.
MOE’s official scoring summary states that Foundation AL A to AL C are mapped to Standard-level AL6 to AL8 respectively for posting. See the MOE PSLE scoring guide and the MOE scoring annex.
This conversion is easy to calculate but easy to overinterpret. AL A contributing 6 points does not erase the fact that the child studied and sat a Foundation subject. Likewise, a Standard AL6 and a Foundation AL A both contributing 6 to the total does not make their papers interchangeable. Use the exact subject level when choosing revision materials, reading a syllabus or discussing secondary placement.
Think like a CivDJ master channel: the total mixes several subject signals into one posting number, but each channel still carries its own source. The total helps route the next stage. The separate subject result helps explain where the learner may begin within that stage.
3. How do you calculate a mixed-level PSLE Score?
The basic method is to convert every subject result into the numeric value used for the overall PSLE Score, then add the four values. Standard results already appear as AL1 to AL8. Foundation results first need the A/B/C mapping. The possible overall PSLE Score range remains 4 to 32.
| Example subject result | Value added |
|---|---|
| Standard English: AL4 | 4 |
| Foundation Mathematics: AL A | 6 |
| Standard Science: AL5 | 5 |
| Standard Mother Tongue: AL3 | 3 |
| Overall PSLE Score | 4 + 6 + 5 + 3 = 18 |
In the first example, the overall PSLE Score is 18. Write the subject level beside every grade when discussing it: Standard English AL4, Foundation Mathematics AL A, Standard Science AL5 and Standard Mother Tongue AL3. Saying only “4, 6, 5, 3” hides the Foundation-to-numeric conversion and invites the false idea that every component came from an identical scale.
| Example subject result | Value added |
|---|---|
| Standard English: AL6 | 6 |
| Foundation Mathematics: AL B | 7 |
| Foundation Science: AL A | 6 |
| Foundation Mother Tongue: AL C | 8 |
| Overall PSLE Score | 6 + 7 + 6 + 8 = 27 |
In the second example, the overall PSLE Score is 27. The two values of 6 come from different reported outcomes: Standard English AL6 and Foundation Science AL A. They add the same numeric amount to the total, but parents should preserve the exact labels when checking subject-level options, revision needs and the receiving school’s instructions.
Use a simple four-line calculator rather than mental shorthand. Copy the result exactly, mark S or F beside each subject, convert only the Foundation letters, add once, and check again. Do not estimate the grade from a school preliminary-examination percentage: the official PSLE result is the authoritative value for posting.
If the child has an approved exemption or another language arrangement, do not invent a fourth subject or apply a generic online example. Use the child’s official result and the specific MOE/SEAB instructions for that arrangement.
4. What does a Foundation score mean for secondary school?
The overall PSLE Score supports Secondary 1 posting, while individual subject results can matter for the starting level of particular secondary subjects. Under Full Subject-Based Banding, Posting Group 1, 2 or 3 is not a command that every subject must remain at G1, G2 or G3. The child’s actual secondary subject portfolio depends on the applicable eligibility rules and the school’s offered arrangements.
| Primary result signal | What it can help decide | What it does not decide alone |
|---|---|---|
| Overall PSLE Score | Posting Group eligibility and school posting under the cohort’s rules | Every individual secondary subject level |
| Foundation AL A/B/C | The reported achievement in that Foundation subject and its 6/7/8 contribution | A permanent label for the learner |
| Individual PSLE subject result | Possible subject-level eligibility or school review under current rules | The child’s whole timetable without the school’s offer |
| Later school evidence | Whether support, bridging or a level change may be appropriate | A retroactive change to the PSLE result |
A Foundation AL A can be a meaningful success: the child demonstrated strong performance within the Foundation band and contributes 6 points for that subject. It is still not a promise of a particular school, Posting Group or secondary subject level. School choice patterns, posting rules, tie-breakers, eligibility criteria and actual subject offerings all matter.
Avoid comparing a Foundation raw mark with a Standard raw mark as though the papers were interchangeable. The clean comparison is within the applicable subject specification and reported grade. For learning decisions, compare the child’s present knowledge with the prerequisites of the next curriculum level, not with another pupil’s percentage from another paper.
Parents can ask three questions after receiving results: What is the exact reported level and grade for each subject? How was each Foundation grade converted in the total? Which secondary subjects and levels is the child eligible or invited to offer? Those questions move from certificate to calculation to next action without skipping a gate.
For the primary decision process, read How Does Subject-Based Banding Work in Primary School?. For a mixed-level example, use Can My Child Take Foundation Maths and Standard English at PSLE?. For Posting Groups and secondary subject levels, open Does Posting Group Decide Every Subject Level?.
The final rule is pleasantly simple: read the Foundation letter accurately, convert it only for the total, and keep the original subject level visible when planning what comes next. One number routes; the full learning profile teaches.
