If you're a Singapore parent with a child in P5 or P6, the PSLE scoring system probably feels like a foreign language. AL1, AL8, Foundation, Higher Mother Tongue, S1 Posting Score — the acronyms pile up fast. This guide explains the Achievement Level system in plain English: what it is, how it's calculated, what counts as a good score, and how long it will be the law of the land.
What is the PSLE AL scoring system?
The Achievement Level (AL) system is the official PSLE scoring system in Singapore. It grades each of the four PSLE subjects on an 8-band absolute scale from AL1 (highest) to AL8 (lowest), based on the actual marks the student earns. Your child's total PSLE score is the sum of their four AL bands.
The key word is absolute. Under the old T-score system, your child was ranked against the entire cohort — so a student could score 80% and still get a lower T-score if everyone else also scored 80%. Under AL, the bands are fixed: if you score in the AL1 range, you get AL1, full stop. The system rewards what your child knows, not how they compare to other ten-year-olds.
What replaced the T-score, and when did the change happen?
The T-score was retired and replaced by the AL system in 2021. The 2021 P6 cohort was the first to sit the PSLE under AL rules.
The Ministry of Education's stated reasons for the change were:
- Reduce hyper-competition. T-scores produced fine-grained rankings (e.g. 252 vs 251) that drove parents to chase marginal mark differences. AL bands deliberately group similar scorers together so the rank between students becomes coarser.
- Recognise mastery, not relative position. A child who genuinely understands the material gets an AL1 regardless of how the rest of the cohort performed.
- Reduce pressure on subject choice. With fewer fine-grained rank gaps, two children with similar mastery end up with similar PSLE scores, making secondary school posting less of a lottery.
The reform was first announced by MOE in 2016, refined through several pilots and consultation rounds, and went live for the 2021 PSLE.
How are the AL bands calculated?
Each subject is independently graded into one of 8 bands. Here are the official mark cut-offs:
| AL band | Raw mark range |
|---|---|
| AL1 | 90 – 100 |
| AL2 | 85 – 89 |
| AL3 | 80 – 84 |
| AL4 | 75 – 79 |
| AL5 | 65 – 74 |
| AL6 | 45 – 64 |
| AL7 | 20 – 44 |
| AL8 | below 20 |
A child who scores 88 in Math gets AL2 in Math, regardless of how the rest of the cohort did. Note that the bands are not evenly sized — AL5 covers 10 marks, AL6 covers 20 marks. This is intentional. The lower bands are wider so that small mark differences at the lower end don't change the AL band; sharper differentiation is reserved for the top end where secondary school posting decisions are most sensitive.
How is the total PSLE score calculated?
Add the four AL bands together. That's it.
- Best possible total: AL1 + AL1 + AL1 + AL1 = 4
- Worst possible total: AL8 + AL8 + AL8 + AL8 = 32
Lower is better. This trips up most parents at first — coming from any other test in life, a bigger number sounds like a better score. PSLE is the opposite. A child with a total PSLE score of 6 is in the top fraction of the cohort. A child with 28 is in the bottom.
The four subjects are:
- English Language
- Mother Tongue — Chinese (华文), Malay, Tamil, or one of the non-Tamil Indian languages
- Mathematics
- Science
Foundation subjects use a separate scale (AL Foundation A–C plus Foundation 7–8) that maps to AL6–AL8 equivalents when summed into the total. Higher Mother Tongue is not included in the AL total but acts as a tie-breaker during S1 Posting — more on that in the next article in this series.
What is a "good" PSLE AL score in 2026?
The honest answer depends on what secondary school you're aiming for, but here are the broad bands as a reference:
- AL 4 – 8: exceptional. Integrated Programme (IP) schools — Raffles Institution, Hwa Chong Institution, Methodist Girls', etc. — are realistic.
- AL 9 – 14: strong. Most Express stream affiliated and top non-affiliated schools.
- AL 15 – 20: solid Express. The bulk of mainstream Express stream schools.
- AL 21 – 25: mid-tier Express, with some Normal (Academic) options.
- AL 26 – 30: Normal (Academic) stream. Subject-based banding lets strong students access Express-level subjects.
- AL 31 – 32: Normal (Technical) stream.
These are bands of possibility, not guarantees. The actual cut-off score for any specific school depends on demand each year. We cover school-specific cut-offs in detail in Singapore secondary school PSLE cut-off scores (reference).
How long will the AL scoring system be in place?
There is no announced end date for the AL system. As of 2026, it has been in continuous use since 2021 and remains the official PSLE scoring system. The Ministry of Education has not signalled any plan to revise the bands or replace the system with a new one.
Two practical implications:
- The AL system applies to the 2026, 2027, and 2028 PSLE cohorts (the children currently in P3 through P6).
- Reform-style headlines are not pending. Don't get distracted by every "new PSLE format" rumour that circulates on parent groups — substantive scoring changes get announced by MOE 12–24 months in advance, and there's nothing of that nature in the pipeline.
If MOE does announce a change in future, we'll cover it on this blog and notify users of the app directly. For now, plan and prepare against the AL system.
What does this mean for how your child should prepare?
The shift from T-score to AL changes the prep strategy in three ways most parents miss:
- Marginal marks matter less than band thresholds. Going from 84 to 85 marks in Math moves you from AL3 to AL2 — a one-mark difference flips a whole band. Going from 90 to 95 stays AL1. So the most valuable practice is not "polish what you already know" but "identify which subjects sit just below a band threshold and push them over."
- You can't grind into a higher band — you have to earn it. Under T-score, raw effort and volume of practice could nudge your relative rank up. Under AL, only actual mark improvements move bands. Practising weak topics is worth far more than re-doing topics you've already mastered.
- A balanced score profile beats a lopsided one. A child with 6 / 7 / 7 / 7 (total 27) gets the same total as one with 4 / 7 / 8 / 8 (also 27), but the lopsided profile signals to secondary schools that there's a subject the student can't keep up with. Even out the bands before chasing AL1 in one subject.
That last point is exactly why PSLE Alex builds practice queues around your child's weakest topics rather than serving more questions on what they already know. Every minute spent on AL1 material is a minute not spent moving an AL5 subject into AL4.
Summary
The PSLE AL system is here, it's stable, and it's the rules of the game for the next several years at least. Lower is better. Bands are absolute. The single highest-leverage prep move is to find which subjects sit just below a band threshold and push them over.
In the next article in this series we'll cover how that final AL total feeds into the S1 Posting algorithm — and what choices you have to make on the secondary school list when the score lands.
