From PSLE to Secondary 1: how S1 Posting actually works in Singapore

📚 PSLE → Secondary School series · Part 2 of 3. ① AL scoring system → ② From PSLE to S1 Posting (you're here) → ③ Cut-off scores.

PSLE results land — now what? Secondary 1 (S1) Posting is the mechanical step that turns your child's four AL bands into an actual school place. Here's exactly how it works, the tie-break that decides close calls, and how to build the 6-school list.

The 30-second version

• PSLE results out in late November.
• You rank up to 6 schools in true order of preference on the portal.
• MOE sorts all students by total PSLE score, lowest (best) first, then posts each to the highest-ranked school on their list that still has space.
• Results released mid-to-late December; Secondary 1 starts in January.
• Your child also gets a Posting Group (1–3) — this replaced Express / Normal streams from 2024.

How the algorithm decides — and the tie-break

It's a strict score-order sort: best scores get first pick of seats. When two students with the same score want the same school's last seat, the tie-break runs in this order:

1. Citizenship — Singapore Citizen → PR → International Student
2. School choice order — a school you ranked #2 beats someone who ranked it #4
3. Computerised balloting — random (only ~1 in 10 ties reach this stage)

⚠️ Higher Mother Tongue is not a tie-breaker under the AL system — an outdated claim you'll still see in old guides. Choice order is the lever you control. (MOE tie-breaker rules.)

Worked example — Wei Ming, PSLE score 12. He ranks a stretch school (cut-off ~10) at #1, three realistic schools (cut-off ~12) at #2–4, two safety schools (cut-off ~16) at #5–6. He misses #1. At #2 he ties with others for the last seat; he's a Singapore Citizen who ranked it #2, so he beats a PR and anyone who ranked it lower → posted to choice #2.

Posting Groups (Full Subject-Based Banding)

¹ PG1 also requires AL7 or better in English & Maths. Scores 21–22 can be posted to PG2 or PG3.

The Posting Group is the default level, not a locked one — a PG2 student strong in Maths can still take Maths at G3. (What are Posting Groups.)

Four ways into Secondary 1

Building the 6-school list

• Mix: 1 stretch · 3 realistic · 2 safety. Stretch = cut-off 1–2 AL better than your child's score; realistic = within ±1 AL; safety = 3+ AL of cushion.
• Use last year's cut-off as a floor, not a prediction — it drifts 1–2 AL each year. (See the cut-off scores guide.)
• List true preferences. There's no benefit to "saving" a top choice for a later slot — if your child qualifies, they're in. The only rule: never rank a school you wouldn't accept as a safety.

Timeline

What this means for prep

• Target the cut-off, not the maximum. Aiming for an AL14 school? Don't chase AL8 — make sure you don't slip to AL16. Protect the threshold by closing weak-topic gaps in the subjects most likely to band-flip.
• Posting Group first, school second. Crossing the AL20 / AL24 thresholds matters more than one specific school name.

That's the loop PSLE Alex is built around: practice routed at the topics most likely to move a band, not more of what's already mastered.
