You're at the school gate in P4 and another parent mentions their child's "PSLE aggregate". You nod. You say something like "yes, it's so different now isn't it". You go home. You Google it for 45 minutes. You come out less sure than when you started.

This happens to a lot of parents. The AL scoring system replaced the old T-score in 2021 and it's genuinely unfamiliar if you went through the Singapore school system yourself. The concepts are simple once someone explains them clearly. Here's that explanation.

What the AL score actually is

AL stands for Achievement Level. It's a number from 1 to 8 that describes the band your child's raw score falls into for each subject.

That's all it is. A band. If your child scores 87% in English, they're in AL2. If they score 72% in Math, they're in AL5. The AL score doesn't compare your child to other children. It compares their score to a fixed set of boundaries. Those boundaries don't move based on how other children perform.

This is the fundamental shift from the old system. Your child's AL score is determined entirely by their own raw score. What the rest of the cohort scored is irrelevant.

Key takeaway: An AL score is a fixed band based on your child's raw score. It doesn't change based on how other children perform.

The full AL1 to AL8 table

Here's the full breakdown as set by MOE:

AL Score	Score Range
AL1	90 to 100
AL2	85 to 89
AL3	80 to 84
AL4	75 to 79
AL5	65 to 74
AL6	45 to 64
AL7	20 to 44
AL8	Below 20

Lower is better. AL1 is the highest achievement level. AL8 is the lowest.

Notice something about how the bands are sized. AL1 is a 10-point band. AL5 is also a 10-point band. AL6 is a 20-point band. The bands are not equal in size, and that's intentional.

How the aggregate score works

Your child sits PSLE in four subjects: English, Mother Tongue, Mathematics, and Science. Each subject produces one AL score. The four AL scores are added together to get the aggregate.

Lower aggregate is better.

The best possible aggregate is 4. That's four AL1s, meaning 90% or above in all four subjects. The highest possible aggregate is 32, meaning AL8 in all four subjects.

A child with an aggregate of 8 has averaged AL2 across their four subjects. A child with an aggregate of 16 has averaged AL4. These are rough ways to think about it, though the combinations vary.

What this means practically: you're no longer looking at a single three-digit score and wondering if 243 is good. You're looking at four numbers that each mean something specific. English AL2, Math AL3, Science AL2, Mother Tongue AL3 gives an aggregate of 10. That's a clear, readable picture of where a child performed strongly and where there's room to improve.

Key takeaway: PSLE aggregate = sum of four AL scores. Lower is better. Best possible is 4. Most competitive Express schools look for aggregates in the range of 6 to 9.

What happened to the T-score (and why the change matters)

The old T-score ranked every child in Singapore against every other child who sat PSLE that year. Your child's score wasn't about what they knew. It was about where they stood relative to the entire cohort.

This created a specific and well-documented problem. A child who scored 90% on a Math paper might receive a low T-score if the rest of Singapore scored 93% that year. Their absolute performance was strong. Their relative performance made their score look weak. Nothing about their understanding had changed, but their score had.

This made every single mark in every single paper feel like it could shift a child's secondary school placement. Parents and children felt this acutely. The anxiety around PSLE under the T-score system wasn't imaginary. It was structurally baked in.

MOE changed to the AL system to move away from that norm-referenced competition. Under the AL system, a child who scores 84% in Math gets AL3. Full stop. It doesn't matter if the national average that year is 86% or 78%. Their score is their score.

The change also means that a child who scores 84% and a child who scores 80% both receive AL3. They are, for PSLE placement purposes, equivalent. That one-to-two mark difference that used to carry enormous weight under the T-score no longer carries it here.

What this means for secondary school placement

Secondary school placement is based on the aggregate score. Lower aggregate children are given priority.

As a rough guide, the most popular Express stream schools in Singapore typically look for aggregates in the range of 6 to 9. Schools offering the Integrated Programme, or IP track, are more competitive. But these are historical guides, not fixed rules. Cut-off points shift from year to year based on available places and the specific cohort applying.

What the AL system doesn't do is eliminate competition for the most popular schools. Tie-breaking criteria still exist. When two children have the same aggregate, the next tiebreaker is based on citizenship, then on a computerised balloting system.

For families in the west of Singapore, near Ghim Moh, Clementi, or Ulu Pandan, schools like Nan Hua High, New Town Secondary, and Queenstown Secondary draw many applications each year. The cut-off aggregates for these schools are worth checking against MOE's most recent data, not older estimates from parents at the school gate.

Common questions parents ask us about AL scores

We hear the same questions from families in our Ghim Moh centre regularly. Here are the ones that come up most.

"Does Mother Tongue count the same as English?" Yes. All four subjects are weighted equally. Each contributes one AL score to the aggregate.

"What if my child is doing Higher Chinese or Higher Malay?" Higher Mother Tongue is a separate consideration. If your child takes Higher Mother Tongue and scores AL1 or AL2, there is a bonus provision. The specifics are governed by MOE's current guidelines and are worth checking directly on the MOE website.

"Is Science optional?" Science is part of the standard PSLE for most students. Children in the MOE Foundation stream may sit different papers. If you're unsure which pathway applies to your child, their school's subject teacher is the right person to ask.

Frequently Asked Questions

My child got AL3 in Math. Is that good?

AL3 means a raw score of 80 to 84%. That's a strong performance. Whether it's "good enough" depends on which secondary school your child is aiming for. For most mainstream Express stream schools, AL3 in Math is more than adequate. For highly competitive schools or IP schools, AL1 or AL2 may be needed across all subjects.

Can my child's aggregate change after results are released?

No. The AL bands are fixed and the aggregate is calculated from the official marked scripts. If you believe there's been a marking error, MOE has a formal process for requesting a re-mark. But the AL system doesn't adjust scores post-release.

My child is in P4. Should I be worried about AL scores now?

P4 is a good year to understand the system, not to panic about it. What matters at P4 is building strong foundations in English, Math, Science, and Mother Tongue. The AL bands become relevant when your child approaches PSLE. Right now, focus on whether they understand the concepts they're learning, not on projecting AL scores from primary school exam results.

We've heard that the cut-off for a certain school is "aggregate 8". Does that mean my child needs four AL2s?

Not necessarily. An aggregate of 8 can come from many combinations. AL2, AL2, AL2, AL2 (four subjects at AL2) gives aggregate 8. So does AL1, AL2, AL2, AL3. Or AL1, AL1, AL3, AL3. The combination doesn't matter, only the total. Cut-off aggregates also vary each year, so treat any number you hear as a rough historical guide, not a guarantee.
