How PSLE Posting Works: Singapore AL Scoring & School Placement

Every year, over 38,000 Primary 6 students in Singapore participate in the Secondary 1 (S1) posting exercise after receiving their PSLE results. The posting outcome determines which secondary school a child will attend, making it one of the most significant milestones in a student's academic journey. Understanding exactly how the system works helps parents and students make informed decisions during the school selection process.

Since 2021, Singapore's Ministry of Education (MOE) has used the Achievement Level (AL) scoring system to replace the old T-score system. The PSLE posting system is a merit-based secondary school allocation process that assigns Primary 6 students to secondary schools based on their Achievement Level (AL) scores, school choices, and eligibility criteria set by MOE. Students with a lower total AL score are posted first, and the system processes all six school choices before moving to the next-ranked student — meaning a student's first-choice school is always considered before any lower-ranked applicant is placed.

Understanding the PSLE Achievement Level (AL) Scoring System

Under the AL system, each of the four PSLE subjects — English Language, Mother Tongue Language, Mathematics, and Science — is scored on a scale of AL1 to AL8. AL1 represents the highest achievement (90 marks and above), while AL8 indicates a score below 20 marks. The scoring bands are calibrated so that each AL band represents a comparable level of achievement regardless of subject difficulty, eliminating the fine differentiation of the old T-score system.

The raw mark ranges for each AL band are as follows: AL1 (90–100), AL2 (85–89), AL3 (80–84), AL4 (75–79), AL5 (65–74), AL6 (45–64), AL7 (20–44), and AL8 (below 20). A student's total PSLE Score is simply the sum of their AL scores across all four subjects. The best possible score is 4 (AL1 in every subject), and the theoretical maximum is 32 (AL8 in every subject), though MOE reports that most students score between 8 and 22.

How the Secondary 1 Posting Process Works

The S1 posting exercise follows a clear step-by-step procedure administered by MOE. After receiving their results, students submit up to six secondary school choices in order of preference. The posting algorithm then processes students one by one, starting with the lowest total AL score. Here is how the ranking order works:

First, all students are ranked by their total PSLE Score — lower is better, so a student with a score of 8 is ranked ahead of a student with a score of 10. If two students share the same total score, the tie is broken by citizenship status: Singapore Citizens are posted first, followed by Permanent Residents, then International Students. If citizenship is also the same, the next tie-breaker is the student's order of school choices — a student who ranked a school as their first choice gets priority over someone who ranked it second. If all these factors are equal, MOE uses a computerised ballot to determine posting.

This process means that parents should list schools in genuine order of preference, not try to game the system. Because the algorithm always considers a student's higher-ranked choices before moving to their lower-ranked ones, there is no disadvantage to listing competitive schools as first and second choices. If a student does not qualify for any of their six choices, MOE will post them to a school with available vacancies near their residence that still has places.

Direct School Admission (DSA) and Its Impact on Posting

Students who receive a confirmed offer through the Direct School Admission (DSA-Sec) exercise are posted to their DSA school regardless of their PSLE Score, provided they meet the eligibility criteria for a secondary school course. DSA results are released alongside the PSLE results, and students with confirmed DSA offers do not participate in the S1 posting exercise. This route accounts for roughly 20% of secondary school placements each year and is particularly relevant for students with talents in sports, performing arts, or specific academic areas.

Posting Groups Under Full Subject-Based Banding

Since 2024, MOE has been progressively implementing Full Subject-Based Banding (Full SBB) across all secondary schools. Under this framework, the traditional Express, Normal (Academic), and Normal (Technical) streams are being replaced by three Posting Groups: G1, G2, and G3. These posting groups correspond broadly to the old streams — G3 maps to the Express level, G2 to Normal (Academic), and G1 to Normal (Technical) — but with the crucial difference that students can take individual subjects at higher or lower levels based on their strengths.

The indicative AL score ranges for each posting group are published by MOE before the S1 posting exercise each year. For reference, schools offering the Express course (Posting Group 3) typically have indicative score ranges between 4 and 22, while Normal (Academic) courses (Posting Group 2) range between 21 and 25, and Normal (Technical) courses (Posting Group 1) range between 26 and 30. These ranges vary by school and are updated annually based on the previous year's posting results.

Making Informed School Choices

Choosing six secondary schools requires balancing several factors. Parents and students should consider the school's indicative AL score range, distance from home, the school's distinctive programmes, and its culture and ethos. MOE's SchoolFinder tool provides detailed information about every secondary school, including cut-off points from the previous year's posting exercise, CCAs offered, and subject combinations available. It is advisable to include at least one or two safety schools — those with cut-off points comfortably above the child's expected score — among the six choices.

For students who need additional support with English, a subject that carries equal weight in the PSLE score calculation, targeted preparation can make a meaningful difference. Strong English skills not only improve the PSLE English AL score but also support performance in Science and Mathematics, which require comprehension of word problems and written explanations. At iWorld Learning, our Primary School English programme helps students build the reading, writing, and oral communication skills essential for PSLE preparation, using the CEFR framework to ensure systematic progress.

FAQ

What is the minimum PSLE score needed to qualify for the Express stream?

Under the AL scoring system, students generally need a total PSLE Score of 22 or lower to qualify for the Express course (Posting Group 3). However, specific cut-off points vary by school each year. Schools with higher demand may require scores of 12 or below. MOE publishes indicative score ranges annually before the S1 posting exercise.

Can my child change secondary schools after the posting results are released?

MOE generally does not allow school transfers based on the posting outcome. Students are expected to report to the school they are posted to. In exceptional circumstances such as medical conditions or severe accessibility issues, parents may appeal directly to the posted school or to MOE. Such appeals are rarely successful and require documented evidence.

How does the ballot work when students have identical PSLE scores?

When two or more students share the same PSLE Score, citizenship status, and school choice order, and there are insufficient vacancies for all of them, MOE uses a computerised ballot. The ballot is entirely random and cannot be influenced by any party. This is the final tie-breaker and only affects a small percentage of students each year.

What happens if none of my child's six school choices can accept them?

If a student is not posted to any of their six choices, MOE will post them to a secondary school with available vacancies, typically one near the student's residential address. This school may not have been on the child's original list of choices. To minimise this risk, parents should include at least two schools with cut-off points comfortably above their child's expected score.

Does my child's Mother Tongue Language score affect posting eligibility?

Yes, Mother Tongue Language is one of the four core subjects in the PSLE and contributes equally to the total PSLE Score. Additionally, students who achieve AL1 or AL2 in Higher Mother Tongue Language at the PSLE may be eligible for bonus points that improve their posting chances for SAP (Special Assistance Plan) schools.

Summary

The PSLE posting system is designed to be transparent and merit-based, placing students in secondary schools according to their AL scores, school preferences, and eligibility. Understanding the AL scoring bands, the posting algorithm's ranking logic, and the broader context of Full Subject-Based Banding empowers parents to guide their children through this important transition with clarity and confidence. Making informed school choices, supported by MOE's SchoolFinder tool and realistic expectations, is the most effective strategy for navigating the S1 posting exercise.
