PSLE Grading: Understanding AL Bands and Secondary School Posting

Singapore's PSLE grading system shifted from the T-score to the Achievement Level (AL) scoring system in 2021, changing how primary school leavers are assessed and placed into secondary schools. Under the AL system, each of the four PSLE subjects receives an individual AL score from AL1 to AL8, and a student's total PSLE score is the simple sum of all four subject scores, with 4 being the best possible result and 32 the highest.

The PSLE Achievement Level (AL) scoring system is a banded grading framework that assigns each subject a score from AL1 to AL8 based on a student's raw examination mark, replacing the fine-grained T-score to reduce excessive peer comparison and encourage students to focus on their own learning progress rather than relative ranking. For parents navigating the secondary school posting process, understanding how these bands work and what they mean for school placement is essential.

How the PSLE AL Scoring Bands Work

Each of the four PSLE subjects—English Language, Mother Tongue Language, Mathematics, and Science—is marked on a raw percentage scale and then mapped to one of eight achievement levels. The band thresholds set by MOE are: AL1 (90–100 marks), AL2 (85–89), AL3 (80–84), AL4 (75–79), AL5 (65–74), AL6 (45–64), AL7 (20–44), and AL8 (below 20). These band widths mean that students scoring anywhere within the same range receive identical AL grades for that subject, eliminating the hyper-competitive differentiation that characterised the old T-score era.

To calculate the total PSLE score, parents simply add the four subject ALs together. For example, a child who achieves AL2 in English, AL3 in Mathematics, AL2 in Science, and AL4 in Mother Tongue would have a total score of 11. This transparency stands in contrast to the old T-score formula, which involved statistical normalisation and produced scores that were difficult for families to interpret without additional context.

Students taking subjects at the Foundation level receive grades mapped to AL A, B, and C bands. Foundation AL A is equivalent to AL6, Foundation AL B to AL7, and Foundation AL C to AL8. These Foundation-level grades are incorporated into the total PSLE score using the same additive method, ensuring all students are evaluated on a consistent basis regardless of subject level.

Secondary School Posting Groups Based on PSLE Score

A student's total PSLE score directly determines their eligibility for secondary school posting groups. With the implementation of Full Subject-Based Banding (Full SBB) from 2024, MOE organises students into three posting groups that replace the former Express, Normal (Academic), and Normal (Technical) streams:

• Posting Group 3 (Express equivalent): PSLE score of 4 to 20
• Express / N(A) option band: PSLE score of 21 to 22
• Posting Group 2 (N(A) equivalent): PSLE score of 23 to 24
• N(A) / N(T) option band: PSLE score of 25
• Posting Group 1 (N(T) equivalent): PSLE score of 26 to 30, with AL7 or better in both English Language and Mathematics

Within each posting group, admission to specific secondary schools is still determined by the total PSLE score, with lower total scores receiving priority. When two students share the same score, tiebreakers are applied in this order: Singapore citizenship, school choice order, and computerised balloting. Understanding these mechanics helps families make strategic decisions when listing their six secondary school choices during the S1 Posting Exercise.

What Full Subject-Based Banding Means for Your Child

Under Full SBB, students are no longer locked into a single academic track for all subjects. Instead, they take individual subjects at different levels—G3, G2, or G1—based on their PSLE performance in each subject. This means a student placed in Posting Group 2 could still study English at the G3 level if their PSLE English AL score meets the threshold set by their secondary school. The system is designed to give every child access to appropriately challenging coursework across the curriculum, rather than a one-size-fits-all academic band.

How English Performance Affects PSLE Score and Posting Options

English Language is one of the four scored PSLE subjects, but its influence extends well beyond its individual AL grade. A strong English foundation directly supports performance in Science, where experiment-based questions demand careful reading comprehension, and in Mathematics, where problem sums require precise interpretation of written scenarios. Additionally, the Posting Group 1 eligibility criteria explicitly require AL7 or better in English, making it a gatekeeper subject that can determine whether a student qualifies for certain secondary school pathways.

For families looking to strengthen their child's English skills ahead of the PSLE, iWorld Learning's primary school English programme offers small classes led by internationally certified teachers who are experienced with the demands of Singapore's MOE English syllabus, covering reading comprehension, writing, oral communication, and listening components.

Common Misconceptions About PSLE AL Grading

One widespread misunderstanding is that a single AL improvement in a subject is negligible. Because the AL bands span up to 10 raw marks—for instance, AL5 covers 65 to 74—moving from AL5 to AL4 requires crossing the 75-mark threshold, which represents a substantial leap in performance. Parents should focus on sustained, meaningful progress rather than marginal mark-chasing, which was a known shortcoming of the T-score system.

Another misconception is that the broader AL bands make it harder to enter popular secondary schools. In practice, because more students share the same total AL score, competition at specific score points can intensify. However, the option bands at scores 21–22 and 25, combined with the tiebreaker hierarchy, give families more flexibility than they may initially assume. The key is understanding the range of schools accessible at your child's score band rather than fixating on a single target school.

FAQ

What is the difference between PSLE AL scores and the old T-score system?

The AL system uses eight broad achievement bands per subject (AL1 to AL8), while the T-score was a finely differentiated mark calculated through statistical normalisation that compared each student against their peers. The AL system measures each child against a fixed standard of performance rather than against other students, reducing excessive competition. A total PSLE score under AL ranges from 4 to 32, making it far simpler to interpret than the T-score, which could range from approximately 60 to over 280.

What is considered a good PSLE score for the Express stream?

A total PSLE score of 20 or below qualifies a student for Posting Group 3, the Express-equivalent grouping. Scores between 4 and 10 are generally regarded as strong and can open doors to the most competitive secondary schools with higher cut-off points. That said, what counts as a good score ultimately depends on your child's academic goals and the schools they hope to enter, not on an arbitrary benchmark.

Can my child retake the PSLE if the results are unsatisfactory?

The PSLE is a one-time national examination, and MOE does not offer a formal retake option. Students whose total scores do not meet the eligibility criteria for any posting group should consult their primary school for guidance on available pathways, which may include repeating Primary 6 or exploring alternative educational routes. The best approach is consistent, thorough preparation across all four subjects, with particular attention to English given its foundational role in overall PSLE performance.

How does the PSLE grading system accommodate students with learning needs?

Students with documented learning needs may be granted access arrangements during the PSLE, such as additional time, separate room seating, or the use of assistive technology. These arrangements are approved by the Singapore Examinations and Assessment Board (SEAB) on a case-by-case basis and do not alter how AL grades are assigned. The AL scoring framework applies uniformly to all candidates, with accommodations addressing equitable access rather than adjusting grading standards.

When are PSLE results released and how does the secondary school posting process work?

PSLE results are typically released in late November each year. After receiving their results, students have a window of several days to submit their six secondary school choices through the Secondary 1 (S1) Posting Exercise. The posting results are usually announced in late December, giving families a short period to prepare before the new school year begins in January. Students are posted based on merit—lower total PSLE scores get priority—followed by the tiebreaker hierarchy of citizenship, choice order, and balloting where necessary.

Summary

The PSLE AL grading system replaces relative ranking with a transparent, standards-referenced assessment model. By grouping raw marks into eight achievement levels and summing them across four subjects, it gives families a clearer picture of a child's academic standing. Understanding how AL bands determine secondary school posting groups—and how Full Subject-Based Banding introduces subject-level flexibility—empowers parents to make well-informed decisions about their child's secondary school journey.
