How PSLE AL Bands Work: Singapore's Secondary School Scoring System

The Primary School Leaving Examination (PSLE) Achievement Level (AL) scoring system replaced the T-score in 2021, marking the biggest shift in how Singapore assesses primary school students in decades. Instead of ranking children against their peers with a fine-grained aggregate score, the AL system places each subject result into one of eight broad bands — from AL1 (the highest) to AL8 — and sums them to produce a total PSLE Score between 4 and 32.

For parents navigating their child's final primary school years, understanding exactly how AL bands work is not just academic interest — it directly shapes school choices, subject combinations, and realistic expectations about secondary school posting. This guide covers every component of the system: what each AL band represents, how raw examination marks translate into AL scores, and how the total score determines which secondary school your child may enter.

What Are PSLE Achievement Level (AL) Bands?

PSLE Achievement Level (AL) bands are scoring categories introduced by Singapore's Ministry of Education (MOE) that group raw examination marks into eight broad performance levels, replacing the older T-score system to reduce excessive fine differentiation among students. Each subject a student sits — English Language, Mathematics, Science, and Mother Tongue Language — receives its own AL score from 1 to 8 based on the raw mark achieved.

The eight AL bands and their corresponding mark ranges are:

• AL1: 90 marks and above
• AL2: 85 to 89 marks
• AL3: 80 to 84 marks
• AL4: 75 to 79 marks
• AL5: 65 to 74 marks
• AL6: 45 to 64 marks
• AL7: 20 to 44 marks
• AL8: Below 20 marks

One notable feature of this system is that mark ranges are not evenly distributed. The top bands — AL1 through AL4 — span only five raw marks each, while the middle and lower bands (AL5 and AL6) cover wider ranges of 10 and 20 marks respectively. This design intention reflects MOE's goal: the narrower bands at the top discourage the high-stakes competition over every single mark that characterised the T-score era, while still distinguishing genuinely different levels of subject mastery.

How Is the PSLE Score Calculated?

A student's total PSLE Score is the sum of the AL scores from all four subjects. Because each subject contributes an AL between 1 and 8, the total PSLE Score ranges from 4 — the best possible outcome, meaning AL1 in every subject — to 32. There is no weighting, no scaling, and no comparison with other students' results.

This is fundamentally different from the old T-score, which calculated each student's position relative to the cohort and produced a score that varied from year to year. Under the AL system, a child's result depends entirely on their own performance against fixed mark standards. If every Primary 6 student in Singapore performed well in a given year, they would all receive good AL scores — there is no bell-curve adjustment.

How Raw Exam Marks Map to AL Bands

Mapping raw marks to AL bands is straightforward: a student who scores 87 in English receives an AL2 for that subject; a student who scores 91 in Mathematics receives an AL1. The process is applied independently to each of the four subjects, meaning a child might score AL1 for Mathematics and AL3 for Science in the same examination.

For students taking one or more subjects at Foundation level rather than Standard level, the AL scoring operates differently. Foundation subject results map to AL scores from AL6 (equivalent to AL A, 75 to 100 marks at Foundation level) to AL8 (AL C, below 30 marks). This means a child taking Foundation Mathematics cannot score better than an AL6 in that subject, which is an intentional design that reflects the different curriculum breadth of Foundation-level study.

How AL Bands Affect Secondary School Posting

Your child's total PSLE Score is the primary factor determining which secondary school they can enter. Each secondary school publishes indicative cut-off points for its courses based on the previous year's posting exercise. The lower the total PSLE Score, the wider the range of schools and courses available.

Under Full Subject-Based Banding, introduced progressively from 2020 and fully implemented in 2024, secondary schools now use three Posting Groups — G1, G2, and G3 — which correspond broadly to the former Normal (Technical), Normal (Academic), and Express streams respectively. A student with a PSLE Score of 4 to 20 generally qualifies for posting to G3 (Express), while scores of 21 to 25 typically map to G2, and scores of 26 to 30 with AL7 or better in both English and Mathematics map to G1. Full SBB also means students can take individual subjects at a more demanding level based on their subject-specific strengths rather than being confined to a single stream across all subjects.

Choosing Schools Based on AL Score

When PSLE results are released, parents and students receive a booklet listing secondary schools and their courses alongside the previous year's cut-off points as a reference. Because cut-off points shift slightly each year depending on demand and cohort performance, MOE recommends listing schools in order of genuine preference rather than attempting to game the system — the posting algorithm prioritises a student's choice order over their raw score, provided they meet the school's cut-off.

English Language is the single most consequential subject in this equation. Not only does it carry equal weight in the PSLE Score, but strong English skills are foundational to success across all secondary school subjects, from Science and Mathematics to the Humanities. Many parents at iWorld Learning enrol their children in primary school English programmes well before the PSLE year to build the reading comprehension, writing, and oral communication skills that underpin AL-level performance.

Frequently Asked Questions

When did PSLE AL bands replace the T-score system?

The AL scoring system was introduced starting with the 2021 PSLE cohort. Students who sat the PSLE in 2021 were the first to receive Achievement Level scores instead of T-scores, and the system has now been in place for several cohorts.

What is considered a good PSLE Score under the AL system?

A PSLE Score of 8 or below (meaning an average of AL2 per subject) is considered strong and typically qualifies students for Integrated Programme schools and top-tier Express-stream schools. A score in the 12 to 16 range still opens up many solid Express school options, while scores above 20 generally lead to Normal (Academic) or Normal (Technical) posting. What counts as "good" ultimately depends on each family's aspirations and the specific schools they are targeting.

Can my child achieve AL1 for English if English is not our home language?

Yes. The PSLE English paper assesses specific skills — comprehension, composition, oral communication, and listening — that can be systematically taught and practised regardless of home language background. Many students from non-English-speaking homes achieve AL1 and AL2 scores through consistent exposure, targeted practice, and quality instruction. The key is starting preparation early enough to build the vocabulary, grammar, and critical reading skills the examination demands.

Do PSLE AL bands affect subject choices in secondary school?

Yes, they do so indirectly. Under Full Subject-Based Banding, students can take individual subjects at a more demanding level than their overall posting group if they demonstrated strength in that specific subject at PSLE. For example, a student posted to G2 could take English at the G3 level if they scored AL1 or AL2 in English. English performance at PSLE is therefore a gateway not just to which secondary school your child enters but also to the level at which they study English and other subjects once there. For students looking to sustain strong English skills into secondary school, programmes like iWorld Learning's middle school English courses are designed to maintain and extend the competencies built during the primary years.

What if my child takes subjects at different levels — some Standard, some Foundation?

This is fully accommodated by the AL system. Each subject is scored according to its own AL band table — the Standard-level table or the Foundation-level table — and the four AL scores are simply added together to produce the total PSLE Score. MOE designed the system so that a student's combination of Standard and Foundation subjects produces a total score that fairly reflects their overall achievement.

FAQ

What are the PSLE AL bands?

PSLE Achievement Level bands are scoring ranges from AL1 (90 marks and above, the strongest) to AL8 (below 20 marks), introduced in 2021 to replace the T-score system. Each subject receives its own AL score, and the total AL score across four subjects determines secondary school posting eligibility.

How does the AL scoring system affect secondary school posting?

A lower total AL score means stronger academic performance. For instance, a total of AL4 to AL8 typically qualifies for the Express stream and Integrated Programme schools, while higher totals may lead to Normal (Academic) or Normal (Technical) streams. Students are ranked first by total AL score, with tie-breakers applied when needed.

Is the AL system easier or harder than the old T-score?

The AL system is neither easier nor harder — it measures achievement differently. Instead of ranking students against one another with fine decimal distinctions, it groups similar performance levels into bands. This reduces excessive competition over single marks but also means small mark differences near band boundaries can affect the final AL grade.

Summary

The PSLE AL band system uses eight broad achievement levels — AL1 through AL8 — to score each of your child's four subjects based on raw examination marks, then sums them into a total PSLE Score between 4 and 32. This total score determines secondary school placement through MOE's posting exercise, which now operates under Full Subject-Based Banding with three posting groups: G1, G2, and G3. The system's fixed benchmarks mean a child's result depends on their own performance rather than how others performed, reducing unnecessary pressure while still providing meaningful differentiation for school posting purposes.

If English is a subject your child needs to strengthen ahead of the PSLE, iWorld Learning's primary school English programme offers small-group classes led by certified TESOL/TEFL teachers with an average of over 20 years of experience. Each student follows a tailored CEFR-based learning path that targets the exact skills the PSLE English paper tests — comprehension, writing, oral communication, and listening.
