Quick Answer: Every PSLE subject — English, Mathematics, Science, and Mother Tongue — is graded on the same Achievement Level (AL) scale from AL1 (90–100 marks, highest) to AL8 (below 20 marks, lowest). Each subject receives its own AL score, and the four subject scores are summed to produce the PSLE total, which ranges from 4 to 32. The grading standard is the same across all four subjects: a 78 in English and a 78 in Math both earn AL4.
Since 2021, PSLE grading has followed a straightforward rule: what matters is the mark range your child falls into, not how their performance compares to anyone else's. The same AL banding applies to all four examinable subjects, and each subject carries equal weight in the final total. This article explains how each subject is graded, what each AL band means for subject mastery, and how parents can interpret a subject-level AL score to guide targeted support.
The Common AL Grading Scale for All PSLE Subjects

The PSLE Achievement Level (AL) grading scale is a uniform eight-band framework that applies identically to English, Mathematics, Science, and Mother Tongue. A given raw mark produces the same AL in any subject — the grading bands do not vary by subject difficulty or cohort performance.
| Achievement Level | Raw Mark Range | What It Means for Subject Mastery |
| AL1 | 90–100 | Comprehensive mastery; student can handle the full syllabus confidently |
| AL2 | 85–89 | Very strong understanding; minor gaps in the most challenging topics |
| AL3 | 80–84 | Good overall understanding; some topics need reinforcement |
| AL4 | 75–79 | Adequate foundation; several topics need targeted improvement |
| AL5 | 65–74 | Basic grasp; significant gaps in understanding across multiple topics |
| AL6 | 45–64 | Partial understanding; substantial gaps; needs structured intervention |
| AL7 | 20–44 | Very limited understanding; foundational concepts not yet secure |
| AL8 | Below 20 | Severe difficulty with the subject; may require foundational re-teaching |
Because the same scale applies to every subject, parents can directly compare their child's AL scores across subjects to identify the weakest link. A child with AL2 in Math, AL3 in Science, AL3 in Mother Tongue, and AL5 in English has a clear target for improvement: English is the subject pulling the total up.
How Each PSLE Subject Is Structured and Scored
While the grading scale is uniform, each subject is assessed through different components. Understanding these components helps parents see where marks are gained and lost within a subject.
English
PSLE English is assessed through four papers, each testing a different skill:
| Paper | Component | Marks | Weightage | What Students Find Challenging |
| Paper 1 | Situational Writing + Continuous Writing | 55 | 27.5% | Task fulfilment, grammar accuracy, organisation |
| Paper 2 | Language Use + Comprehension | 95 | 47.5% | Grammar cloze, comprehension open-ended, synthesis |
| Paper 3 | Listening Comprehension | 20 | 10% | Following extended spoken passages |
| Paper 4 | Oral Communication | 30 | 15% | Reading aloud fluency, stimulus-based conversation |
Paper 2 carries the heaviest weight at 47.5% of the English marks — comprehension open-ended and synthesis are the two sections where students most often drop below their target AL band. Small-group English tuition, such as iWorld Learning's primary-level programme, helps students strengthen these specific components through targeted practice with individual teacher feedback.
Mathematics
PSLE Math comprises Paper 1 (without calculator, 45 marks) and Paper 2 (with calculator, 55 marks). Both papers test number and algebra, measurement and geometry, and statistics. Problem sums in Paper 2 — where students must show working and apply concepts to multi-step problems — are often the differentiator between AL3 and AL2.
Science
PSLE Science tests knowledge with understanding, application of concepts, and process skills through a multiple-choice booklet (56 marks) and an open-ended booklet (44 marks). The open-ended section, where students must explain scientific reasoning in clear written answers, is the most common source of dropped marks — students often understand the science but cannot articulate it precisely enough for full credit.
Mother Tongue Languages
Mother Tongue grading follows the same AL scale. The assessment structure mirrors English in broad outline — oral, listening, writing, and language-use/comprehension components — though the mark distribution and exam format vary by language.
How the PSLE Total Is Calculated
Your child's PSLE total is simply the sum of their four subject AL scores. No subject is weighted more heavily than any other:
PSLE Total = AL (English) + AL (Mathematics) + AL (Science) + AL (Mother Tongue)
Here is what different AL score combinations look like in practice:
| Example | English | Math | Science | MTL | Total | Posting Group |
| Strong across the board | AL2 | AL1 | AL2 | AL2 | 7 | Posting Group 3 |
| Solidly in Express-equivalent | AL3 | AL3 | AL4 | AL3 | 13 | Posting Group 3 |
| Adequate, one weak subject | AL4 | AL4 | AL5 | AL5 | 18 | Posting Group 3 |
| Boundary range | AL5 | AL5 | AL5 | AL6 | 21 | Posting Group 2 or 3 |
| Below Express threshold | AL6 | AL6 | AL5 | AL6 | 23 | Posting Group 2 |
What to Do When One Subject Pulls the Total Down
Because each subject contributes equally, a single weak subject can shift the PSLE total by 2 to 4 points — enough to move the posting group boundary. The most common pattern parents see: a child scores AL2–AL3 in Math and Science but AL5–AL6 in English, or vice versa.
When English is the weak subject, the solution is almost always component-specific: a child may be strong in Paper 2 (grammar and comprehension) but weak in Paper 1 (writing) and Paper 4 (oral). The right approach is to identify the lagging component and target it directly, rather than general "more English practice."
iWorld Learning, a Singapore-based English language school with campuses at Tanjong Pagar MRT and Somerset, uses CEFR-aligned assessments to pinpoint a student's specific English gaps — whether in writing structure, oral fluency, comprehension open-ended, or synthesis — and designs small-group classwork to close them. Their teachers, who hold TESOL and TEFL certifications and average over 20 years of experience, provide the kind of individual feedback that helps a student move from AL5 to AL4 or AL4 to AL3 in English within one academic year.
Frequently Asked Questions
Are all PSLE subjects graded the same way?
Yes. Every PSLE subject uses the same eight-band AL scale with identical mark ranges. A raw score of 78 earns AL4 in English, Math, Science, and Mother Tongue equally. The assessment components differ by subject — English has writing, comprehension, listening, and oral; Math has problem sums and structured questions — but the grading bands are uniform.
How do Foundation-level subjects affect the PSLE total?
Students taking Foundation-level subjects receive an AL score based on a different mark-to-grade mapping designed for the Foundation syllabus. Foundation AL A (75–100 marks) is pegged to AL6 of the standard subject, Foundation AL B (30–74 marks) to AL7, and Foundation AL C (below 30 marks) to AL8. This means a Foundation subject contributes a minimum of AL6 to the PSLE total.
What happens if my child scores AL8 in one subject?
An AL8 (below 20 marks) in one subject adds 8 points to the PSLE total. If the other three subjects score reasonably well, the total may still fall within Posting Group 2 or even Posting Group 3 range (e.g. AL3 + AL8 + AL3 + AL3 = 17, which qualifies for Posting Group 3). However, an AL8 signals substantial difficulty with the subject and warrants targeted intervention before secondary school — the foundational gaps will affect performance in related subjects at the secondary level.
Does English carry more weight than other subjects?
No. English contributes equally with Math, Science, and Mother Tongue to the PSLE total. However, English is the medium of instruction for all other subjects, so weak English often affects performance across the curriculum. A child who cannot read Math problem sums accurately or write clear Science explanations because of English gaps is disadvantaged in more than just the English paper.
How can I help my child improve one specific AL band in English?
First, identify which English component is the weakest — writing (Paper 1), comprehension and language use (Paper 2), listening (Paper 3), or oral (Paper 4). Most P6 students lose the most marks in Paper 2 comprehension open-ended and Paper 1 continuous writing. Once the weak component is identified, focused practice with targeted feedback — such as the small-group English classes at iWorld Learning, where teachers provide individual writing and oral feedback — tends to move the AL band faster than general revision.
Summary
PSLE subjects are graded on a common eight-band AL scale from AL1 (90–100) to AL8 (below 20), and the four subject scores are summed to produce a total between 4 and 32. The uniform scale lets parents quickly identify the subject pulling a child's total down. When that subject is English — the language of instruction for all other subjects — targeted component-level support can shift the AL band and improve performance across the entire curriculum.
If your child's English AL band is the one dragging their PSLE total down, iWorld Learning offers small-group primary English classes that target each component — writing, comprehension, oral, and listening — with individual feedback from internationally certified teachers.
