How PSLE AL Scoring and Secondary 1 Posting Actually Work

Every Primary 6 family in Singapore ends up fixated on a single number: the PSLE Score. Parents compare it, worry about it, and build a year of revision around it. And yet, if you ask most families exactly how that number is built, what a cut-off point actually represents, or how a score turns into a specific secondary school place, the answers get vague fast.

This guide explains the whole mechanism properly — the Achievement Level scoring system, how the four subjects combine, how Secondary 1 posting works, what cut-off points really are, how ties are broken, and how Posting Groups, school affiliation, and DSA fit in. It is written for parents who want to make informed decisions rather than operate on WhatsApp-group folklore, and it is accurate to the current system as of the 2026 academic year.

The Achievement Level system: how the PSLE Score is built

Since the 2021 cohort, the PSLE has been scored using Achievement Levels (ALs) rather than the old T-score aggregate. Each of a student's four subjects — English, Mathematics, Science, and Mother Tongue — is awarded an AL from 1 (best) to 8, based purely on the raw mark for that subject:

The PSLE Score is simply the sum of the four subjects' ALs. The best possible score is 4 (AL1 in all four subjects) and the range runs up to 32 (AL8 in all four). Crucially, a lower score is better — the opposite intuition to a percentage, and a common source of confusion for parents used to "higher is better."

This design is deliberate. Under the old T-score system there were more than 200 distinct possible aggregates, which meant students were finely ranked against one another down to fractions of a mark. The AL system produces only 29 possible scores (4 through 32). The point was to reduce that fine-grained differentiation — to stop a single mark from separating one child from another in the national queue, and to signal that a band of achievement, not a razor-thin rank, is what matters.

Why the bands are uneven — and what that means for revision

Notice that the bands are not equal in width. AL1 to AL4 each span just five marks (90+, 85–89, 80–84, 75–79), while AL5 spans ten marks, AL6 spans twenty, and AL7 spans twenty-five. The top is finely graded; the middle and lower ranges are broad.

There is a practical consequence for how you help your child prepare. The marginal mark matters most near a band boundary. A child sitting on 84 (AL3) who can reach 85 crosses into AL2 — one mark, one whole AL of improvement. A child already on 70 (comfortably mid-AL5) gains nothing in AL terms from reaching 74; both are AL5. Knowing, honestly, where your child sits relative to the nearest boundary, and spending effort where it can actually move an AL rather than where it cannot, matters far more than obsessive mark-chasing.

Foundation subjects and how they count

Students who take a subject at Foundation level are graded A, B, or C rather than on the AL1–8 scale. For the purpose of computing the overall PSLE Score used in posting, those grades are mapped to Standard-level AL-equivalents:

The logic is that a Foundation subject covers a subset of the Standard curriculum, so a strong Foundation grade is treated as equivalent to a lower Standard AL. For a child taking one or more subjects at Foundation level, this mapping is exactly how their overall PSLE Score is assembled. Understanding it before results day means the number won't come as a surprise.

From PSLE Score to a secondary school: how posting works

Here is where most of the folklore lives, so the mechanics deserve a precise explanation.

After results, students rank up to six secondary schools in order of preference. Posting is then done by academic merit first: the student with the best (lowest) PSLE Score is considered first, and placed into the highest-ranked school on their list that still has a vacancy. Then the next student, and the next, until places fill. Every student is posted within the Posting Group they are eligible for (more on Posting Groups below).

That "merit first, then your ranked choices" mechanism has an important, reassuring implication: you should rank schools in your genuine order of preference. Because each student is considered for their first choice before their second, listing an aspirational school first does not "waste" a choice — if your child's score clears that school's demand, they get it; if not, they simply fall through to their next-ranked school. The old anxiety about "strategically" ordering choices is largely a hangover from misunderstanding the system. Rank truthfully, and make sure the lower choices on your list are options your child would be content to attend.

Cut-off points: what they actually are (and aren't)

A school's cut-off point (COP) is simply the PSLE Score of the last student who was posted into that school in a given Posting Group in a particular year — a historical record, not a rule fixed in advance.

Three things follow, and all three are widely misunderstood:

• COPs are indicative, not fixed. The figures published on MOE's SchoolFinder are based on the previous year's cohort and their choices. They can shift by a few points year to year as demand changes.
• A COP is not a quota or an entry requirement. Meeting last year's COP does not guarantee a place this year — if more strong applicants rank the school this year, the effective cut-off tightens.
• They vary by Posting Group within the same school. A school that admits students across Posting Groups will have a different cut-off for each.

Treat COPs as a weather forecast, not a contract. For any school you are seriously considering, check the current ranges on MOE's SchoolFinder rather than relying on a number a friend quoted from two years ago.

What happens when scores tie

Because there are only 29 possible PSLE Scores, ties are more common than they were under the T-score system — many students competing for the last few places at a popular school will have identical scores. When that happens, places are allocated using an official tie-break sequence, applied strictly in this order:

1. Citizenship — Singapore Citizens are placed ahead of Permanent Residents, who are placed ahead of International Students.
2. School choice order — between tied students, the one who ranked that school higher on their own list is placed first.
3. Computerised balloting — used only as a final resort, when citizenship and choice order are also identical.

The second criterion, choice order, was newly introduced with the 2021 revamp, and it reinforces the advice above: ranking a school higher gives your child a genuine (if marginal) edge in a tie for its last seats. Balloting — the part parents fear most — is genuinely a last resort. In practice, roughly one in ten students has ever gone through balloting, while around 80% are posted to one of their top three choices and over 90% to one of their six. The system is far less of a lottery than its reputation suggests.

Posting Groups: the end of streaming

From the 2024 Secondary 1 cohort onward, the old Express / Normal (Academic) / Normal (Technical) streams were replaced by three Posting Groups. Which Posting Group a student is eligible for is determined directly by their PSLE Score:

A couple of details are easy to miss here. There are overlap bands — a score of 21 or 22 lets a family choose Posting Group 2 or 3; a score of 25 lets them choose Posting Group 1 or 2. If your child is eligible for two groups, you must pick one before submitting school choices, and it applies to all six — you cannot mix Posting Groups across your list.

Importantly, a Posting Group is not a stream in the old sense. It determines admission and your child's initial subject levels, but under Full Subject-Based Banding, students then take individual subjects at different levels (G1, G2, G3) according to their strengths. If your child has just been posted and you want to understand what G1/G2/G3 actually mean day to day — and how the new single national exam works — read our companion guide to Full Subject-Based Banding and the end of streaming. And if they have been posted into Posting Group 2, our detailed guide to Normal Academic (G2) pathways walks through the options that follow.

Affiliation priority — what it does and doesn't do

School affiliation (the priority some primary schools' pupils have to a linked secondary school) is frequently misdescribed as a tie-breaker. In reality it's a reserved priority pool, and it works like this:

• Affiliated secondary schools must reserve at least 20% of places in each Posting Group for non-affiliated students — a requirement introduced from the 2019 Secondary 1 Posting Exercise. In effect, affiliation priority is capped at 80% of a school's places per group.
• To claim affiliation priority, a student must meet the school's Affiliate Minimum Requirements and rank the affiliated school as their first choice.
• Affiliated applicants are still posted by merit among themselves — priority gets you into the affiliate pool, but if affiliate demand exceeds the reserved places, PSLE Score decides. Affiliation improves your odds; it does not guarantee a seat.

The reservation rule has opened these schools up. Since the 2021 posting exercise, roughly half of each affiliated school's intake has come from non-affiliated primary schools, and the affiliate-versus-non-affiliate cut-off gap tends to be widest in Posting Group 3 and narrow in the others.

DSA and the posting exercise

If your child secures a place through Direct School Admission (DSA-Sec) and accepts it, they are removed from the Secondary 1 Posting Exercise entirely — they cannot submit school choices and cannot transfer afterward. That is the commitment.

The upside is that a confirmed DSA place is guaranteed regardless of the PSLE Score, provided the result meets the minimum for a Posting Group the school admits — not the school's competitive cut-off. For a school admitting via Posting Group 3, for instance, the student needs a PSLE Score within the Posting Group 3 range (4–22), not the much sharper COP a non-DSA applicant would face. DSA trades away flexibility for certainty, and whether that trade is worth it depends entirely on how confident your family is in the specific school and talent area.

Common myths, corrected

"The AL system removed competition." No — it reduced fine differentiation between students, but competition for popular schools persists at the school level, through cut-off points and tie-breaks. MOE is explicit that meeting a COP does not guarantee admission.

"Posting is basically a lottery." No. It is merit-first; balloting is a last resort that affects roughly one in ten students, and the large majority are posted within their top three choices.

"You need a perfect score of 4 to get into a good school." No. A score of 4 is the best possible, but the cut-offs for even the most sought-after schools sit in the single digits rather than at 4, and plenty of excellent schools have far more comfortable ranges. Chase the right school for your child, not an abstract perfect number — and confirm the actual ranges on SchoolFinder.

"A couple of marks will make or break everything." Only near a band boundary. Within a band, extra marks don't change the AL at all. Knowing where your child sits relative to the nearest boundary is far more useful than blanket panic about every mark.

What this actually means for how you prepare

Step back from the mechanics and a clear preparation principle emerges: the AL system rewards consistent competence across four subjects, not the squeezing-out of one last decimal in a single paper.

Mathematics is one of those four ALs, and it is often the subject where focused effort moves a band most reliably, because maths marks tend to be recoverable through method and practice in a way that, say, comprehension marks are not. But the useful version of "work on maths" is specific: identify whether your child is sitting near a band boundary, target the topics where marks are being lost, and build the steady, broad competence the AL bands reward — rather than drilling frantically in the final weeks. Our guides on what good PSLE Math revision actually looks like and whether online tuition is effective for PSLE go into how to do that well.

The one thing to remember: The PSLE Score is the sum of four Achievement Levels (best is 4), and posting is merit-first — your ranked choices and tie-breaks only decide the close calls. Understand where your child sits relative to the nearest AL boundary in each subject, rank schools by genuine preference, and treat cut-off points as last year's forecast rather than this year's promise.

A note on accuracy: This guide reflects the PSLE AL system and Secondary 1 posting rules as of the current academic year. MOE updates figures and details annually — most importantly, school cut-off points change every year. Always verify current cut-offs and school information directly on MOE's SchoolFinder before making decisions.
