New PSLE Grading System: AL Score, T-Score & Secondary School Posting Explained
Understand the new PSLE grading system, how AL scores are calculated, and the role of T-scores. Learn about secondary school postings, cut-off points, and key changes in the PSLE assessment.

The Primary School Leaving Examination (PSLE) is a crucial milestone for students in Singapore. In 2021, the Ministry of Education (MOE) introduced a new PSLE grading system based on the Achievement Level (AL) score to replace the previous T-score system. This change aims to reduce excessive academic competition and allow students to focus on their learning progress.
This guide provides an in-depth understanding of the PSLE grading system, how the PSLE AL score is determined, and how secondary school postings work under the new system.
???? Understanding the PSLE Grading System
???? Why the Change from T-Score to AL Score?
Previously, students received a T-score (Transformed Score) based on their relative performance compared to their peers. However, this system led to excessive competition over small mark differences. The PSLE AL score system now evaluates students based on absolute performance rather than ranking them against others.
???? How the AL Score Works
The PSLE AL scoring system assigns an Achievement Level (AL) score from 1 to 8 for each subject based on the student's raw marks:
Achievement Level (AL) |
Raw Score Range |
AL1 |
90 – 100 |
AL2 |
85 – 89 |
AL3 |
80 – 84 |
AL4 |
75 – 79 |
AL5 |
65 – 74 |
AL6 |
45 – 64 |
AL7 |
20 – 44 |
AL8 |
Below 20 |
Each subject is graded separately, and the total PSLE AL score is the sum of all four subject scores.
???? How is the PSLE AL Score Calculated?
A student’s PSLE AL score is determined by adding the AL scores of the following four subjects:
-
English Language
-
Mathematics
-
Science
-
Mother Tongue Language (MTL)
Example Calculation:
Subject |
AL Score |
English |
AL2 |
Mathematics |
AL3 |
Science |
AL4 |
Mother Tongue |
AL2 |
Total PSLE AL Score |
11 |
A lower PSLE AL score indicates better performance, with 4 being the best possible score (AL1 in all subjects).

Under the T-score system, students’ marks were adjusted based on the overall cohort’s performance. In contrast, the AL scoring system ensures that students are judged solely on their individual performance.
???? PSLE AL Score & Secondary School Posting
???? PSLE Cut-Off Points for Secondary Schools
PSLE cut-off points (COP) determine the minimum AL score required for admission to different academic streams. Schools set their cut-off points based on previous years’ intake and student demand.
PSLE AL Score |
Secondary School Pathway |
4 – 20 |
Express |
21 – 22 |
Express or Normal (Academic) |
23 – 24 |
Normal (Academic) |
25 – 30 |
Normal (Technical) |
Students with a lower AL score have higher priority in school selection, but availability depends on demand each year.
???? How Secondary School Posting Works
-
Students select up to 6 school choices ranked by preference.
-
Students with lower AL scores are given priority.
-
Tie-breakers apply if multiple students have the same AL score and school choice ranking.
-
Computerized balloting is used if tie-breakers don’t resolve placement conflicts.
???? Tie-Breaking Factors
If multiple students with the same AL score are competing for limited places, the following criteria apply:
-
Singapore Citizens (SC) have priority over Permanent Residents (PR) and international students.
-
Students who placed the school higher on their list will get priority.
-
Balloting is used as a last resort.
???? Advantages of the New PSLE Grading System
✅ Reduces Competition: Encourages students to focus on learning rather than small mark differences. ✅ Fairer Assessment: Students are evaluated based on their own performance, not their peers’ results. ✅ Easier School Selection: Parents and students can make informed choices based on clearer cut-off points. ✅ Greater Learning Flexibility: Encourages students to pursue subjects at a pace suited to their abilities.
???? Key PSLE Timeline & Important Dates

???? How to Prepare for PSLE Under the AL System
For students and parents preparing for PSLE, here are some effective strategies:
???? Understand the PSLE Grading System: Know how the PSLE AL score works to set realistic goals. ???? Focus on Conceptual Learning: Strengthen core understanding in English, Math, Science, and Mother Tongue. ???? Practice Exam Papers: Familiarize yourself with the format and improve time management. ???? Choose Schools Wisely: Consider school cut-off points and available pathways. ???? Maintain a Healthy Balance: Avoid stress by ensuring adequate rest and recreation.
???? Conclusion
The new PSLE grading system and AL scoring system have transformed how students are assessed and placed into secondary schools. By understanding how the PSLE AL score is calculated and how secondary school posting works, students and parents can make well-informed decisions for the future.
