A PSLE Score is the sum of four subject Achievement Levels (ALs), not an average mark or a percentage. Each subject contributes a number from AL1 to AL8, with AL1 being the strongest band. Add the four numbers to obtain an overall score from 4 to 32. In this system, a smaller total is the stronger result. A child with AL2 for English, AL3 for Mathematics, AL4 for Science and AL2 for Mother Tongue has a PSLE Score of 11.
The useful way to read that 11 is in two steps. First, check the addition: 2 + 3 + 4 + 2 = 11. Second, examine each subject separately, because a total cannot tell you which subject is strongest or where support may help. The overall score informs Secondary 1 posting eligibility; the four component ALs help you understand the learning profile. Neither figure tells you everything about your child or guarantees admission to a particular school.
- Calculation: English AL + Mathematics AL + Science AL + Mother Tongue AL = PSLE Score.
- Best possible overall score: 4, from four AL1 results.
- Direction: 10 is a stronger aggregate than 12; the scoring direction is the opposite of a percentage.
- Foundation subject: convert Foundation A, B or C to the applicable equivalent AL before adding.
- Next step: check the official posting group eligibility, then assess school fit and subject strengths separately.
- Important limit: the total is not a percentile, a rank in Singapore, a school place, or a forecast of adulthood.
Start with the four subject results, not the big number
A parent can be drawn to the final total because it looks decisive. It is one number. Yet that number is a summary produced by four other numbers. A more careful reading starts with the four subject rows on the result slip. Locate English Language, Mathematics, Science and the applicable Mother Tongue Language result. Check the AL reported for each subject, including whether any subject is offered at Foundation level. Only after that should you calculate or verify the aggregate.
Why begin there? Imagine two students who both score 12. One has AL3 in every subject: 3 + 3 + 3 + 3 = 12. Another has AL1, AL2, AL4 and AL5: 1 + 2 + 4 + 5 = 12. The overall score is identical. Their educational needs may not be. The second student may have a pronounced strength and a subject that merits closer attention. Neither child is defined by the number, but the subject pattern provides better information than the total alone.
What each Achievement Level means
At Standard level, Singapore’s PSLE uses eight Achievement Levels. They are broad bands of attainment, not eight equal steps on a 100-mark ruler. The published reference mark ranges are:
| Subject AL | Published reference raw-mark band |
|---|---|
| AL1 | 90–100 |
| AL2 | 85–89 |
| AL3 | 80–84 |
| AL4 | 75–79 |
| AL5 | 65–74 |
| AL6 | 45–64 |
| AL7 | 20–44 |
| AL8 | Below 20 |
Notice that the bands have different widths. AL1 contains marks from 90 through 100, but AL6 covers a much wider interval. This is deliberate: an AL is a broad achievement category. A move from AL6 to AL5 should not be interpreted as the same number of raw marks as a move from AL2 to AL1. Nor can the exact raw mark be calculated backwards from the AL printed on the result slip.
For the latest description of the scoring framework, use MOE’s PSLE scoring system. Do not use a remembered T-score rule or a tuition-centre conversion chart in place of the current official framework.
Worked examples: calculate the score yourself
| Example | English | Maths | Science | Mother Tongue | Total |
|---|---|---|---|---|---|
| A | AL2 | AL3 | AL4 | AL2 | 11 |
| B | AL3 | AL3 | AL3 | AL3 | 12 |
| C | AL4 | AL4 | AL5 | AL5 | 18 |
| D | AL1 | AL2 | AL4 | AL5 | 12 |
Example A. English 2 + Mathematics 3 + Science 4 + Mother Tongue 2 = 11. There is no multiplication by a subject weight and no percentage conversion. Example B. Four AL3s give 12. Example C. 4 + 4 + 5 + 5 = 18. Example D. 1 + 2 + 4 + 5 also gives 12. The totals are simple to compute; the meaning of each child’s subject pattern requires more thought.
You do not need to memorise a large conversion table to do this. Read each AL, write the four digits on one line, add carefully, and compare the result with the official overall PSLE Score. If the slip includes a Foundation-level subject, convert the Foundation grade for aggregate calculation as explained below.
What changes if a subject was taken at Foundation level?
A Foundation subject is assessed using grades A, B and C. For deriving the overall PSLE Score used for posting, Foundation A maps to Standard-level AL6, Foundation B maps to AL7, and Foundation C maps to AL8. That mapping is for the aggregate calculation and reflects the different curriculum demands. It does not mean a Foundation A grade is identical to scoring a Standard AL6 on the same paper.
| Foundation result | Equivalent AL used for total |
|---|---|
| Foundation A | AL6 |
| Foundation B | AL7 |
| Foundation C | AL8 |
Suppose a child obtains English AL3, Mathematics AL5, Foundation Science A and Mother Tongue AL5. The posting-score calculation is 3 + 5 + 6 + 5 = 19. Do not add the letter A as 1; that would produce a completely incorrect score. Equally, do not mistake the equivalent AL for a raw mark or for a judgement of potential.
For the more detailed reason that a Foundation A is mapped this way, see Why Does PSLE Foundation AL A Count as AL6?. That guide addresses Foundation scoring specifically; this page focuses on understanding the complete four-subject total.
Why the overall number and the child’s school options are separate questions
The first question is mathematical: what is the score? The second is administrative: which Posting Group or groups may the child use for Secondary 1 admission? The third is educational: which school and learning environment will suit the child? They are connected, but they are not interchangeable.
Under Full Subject-Based Banding, Posting Groups 1, 2 and 3 guide school admission and the starting subject levels. For the applicable framework, scores 4–20 correspond to Posting Group 3; 21–22 allow a choice between Posting Groups 2 and 3; 23–24 correspond to Posting Group 2; 25 allows a choice between Posting Groups 1 and 2; and 26–30 generally correspond to Posting Group 1, subject to the stated English and Mathematics AL requirement. A Posting Group is not itself an Achievement Level. AL1 is a subject grade, whereas PG1 is a school-posting category.
Check the current MOE Posting Groups information rather than assuming the eligibility table will never change. When the child is eligible for two groups, the family must make a deliberate choice that considers pace, readiness and available schools. This is not decided by blindly adding a fifth point or by assuming a larger group number is a higher grade in every circumstance.
Five claims the PSLE Score does not support
- It does not reveal the child’s exact percentage. The AL bands give a range, not the individual raw mark.
- It does not reveal the child’s national rank. The aggregate is not the former T-score and must not be treated as one.
- It does not promise entry to a named school. School posting depends on eligibility, available places, choices and applicable tie-breakers.
- It does not predict performance in every secondary subject. Secondary school introduces new content, pace, assessment styles and learning opportunities.
- It does not sum up a child’s character or potential. The examination measures assessed attainment at a particular point, not kindness, curiosity, creativity or long-term growth.
This distinction matters most when a family is disappointed. The useful question is not ‘What is wrong with my child?’ but ‘What does this result tell us about a sensible starting point and the support needed next?’ A good decision uses the evidence without turning it into a label.
How parents can read the result slip in ten useful minutes
- Read the four subjects. Mark each as Standard or Foundation where applicable.
- Check the arithmetic. Convert any Foundation A/B/C grade to the prescribed equivalent AL, then sum all four.
- Circle the subject pattern. Note clear strengths and one or two areas that may need support.
- Verify the Posting Group eligibility. Use the latest MOE table, including any specific English and Mathematics conditions.
- Separate eligibility from preference. A school can be academically eligible yet inconvenient or unsuitable; a well-loved school can have an uncertain cut-off.
- Ask your child one open question. ‘Which subjects felt most comfortable this year, and what would you like help with in Secondary 1?’
- Use the school-choice window carefully. Consult official instructions and the child’s school, particularly if the result falls in an option band or involves an exemption.
What if the score is close to a school’s previous cut-off point?
A school’s previous PSLE Score range is useful historical information, not a guaranteed entry requirement for the next intake. The last admitted score depends on that cohort’s results, preferences and places available. A family should therefore avoid treating last year’s cut-off as an exact prediction, or relying on all six choices being equally uncertain. This article explains the score; detailed admissions strategy belongs in the separate guide to a score near a school cut-off point.
If your child scored 12, for instance, the correct statement is simply that 12 is the sum of the four subject ALs. Whether a named school is a sensible choice requires its published score range, affiliation or programme conditions where relevant, your child’s preferences, commuting reality and a balanced set of alternatives.
Common parent questions
Is PSLE Score 8 the same as 80 percent?
No. Score 8 might be produced by four AL2 grades, or by another combination that sums to 8. Neither the aggregate nor the AL combination can be converted into one reliable overall percentage. The subjects have different papers and the ALs are bands.
Is an AL2 always just one raw mark below AL1?
No. AL2 covers a published range of raw marks and AL1 covers another. A child near a boundary could be close in marks, while two children in the same AL may also be several marks apart. The result slip is not a raw-mark transcript.
Does the biggest AL number mean the best subject?
No. Within a subject, AL1 is stronger than AL2, and AL2 is stronger than AL3. For the overall PSLE Score too, a lower sum is stronger. This is an easy misunderstanding when families are accustomed to conventional point systems.
Does my child have to keep the same subject levels throughout secondary school?
Not necessarily. Full Subject-Based Banding allows eligible students to take different subjects at levels suited to their strengths and readiness, with schools reviewing progress at appropriate points. Confirm specific subject offers and progression arrangements with the secondary school.
A better final question
Once you can read the score correctly, stop treating the number as a riddle. Use it as a starting map. The score describes overall assessed attainment; the subject ALs add detail; the Posting Group guides an initial route; and the chosen school becomes the environment in which your child will continue learning. Those are four different things. Keeping them separate makes the next decision both more accurate and more humane.
