What does the PSLE Aggregate Score (e.g. ‘score of 231’) mean?
Three common questions
What does this number
mean?
Is this the sum of all 4
subjects?
Is it a raw score?
![Page 4: Sharing on PSLE Scoring - Ministry of Education · 2018. 10. 9. · Sharing on PSLE Scoring @ Curriculum Forum Day 2018 Dr Lau Hock Soon Vice-Principal 3 February 2018 ... English](https://reader035.fdocuments.us/reader035/viewer/2022062613/61453a6134130627ed50d983/html5/thumbnails/4.jpg)
PSLE - a placement examination
• need to reflect the relative achievement
level of students among their peers.
• places students into different courses
according to their academic ability
• enables posting to secondary schools by
merit and as far as possible into a school
of their choice

The PSLE Aggregate Score
• incorporates performance of students
in all 4 subjects
• allows students to be ranked fairly
nation-wide
![Page 6: Sharing on PSLE Scoring - Ministry of Education · 2018. 10. 9. · Sharing on PSLE Scoring @ Curriculum Forum Day 2018 Dr Lau Hock Soon Vice-Principal 3 February 2018 ... English](https://reader035.fdocuments.us/reader035/viewer/2022062613/61453a6134130627ed50d983/html5/thumbnails/6.jpg)
• the raw mark obtained in exam only
shows how good the student is in that
subject, not how good he is compared
to others
• the need to consider the spread of
subject scores from the average mark,
i.e. the standard deviation.
Why raw scores cannot be used?

Narrow Wide

What is T-Score ?
• T-Score converts average mark of each subject
to a common score of 50 points
• converts other marks, taking into consideration
the extent to which they differ from the average
and the spread of the marks around the average
• shows the relative position of a student’s
performance compared to the performances of
all the other students in that subject

How is Aggregate Score calculated ?
By adding the T-Scores of 4 subjects e.g.
Subject Total Mark T-Score
English 200 105 34
Mother Tongue 200 152 51
Mathematics 100 67 53
Science 100 58 47

T-Scores and Grades
Is it possible for a pupil with 3
‘A*’ and 1 ‘A’ to be ranked lower
than another pupil who has only
1 ‘A*’ and 3 ‘A’?

may not necessarily remain at 230
