PSLE is a placement exam
What is the PSLE Aggregate SCORE?
Why is T-Score used?
Definition & Calculation of T-Score
Questions about T-Score 18
PSLE is a Placement Exam
Shows the relative achievement level of pupils within their peers.
Places pupils 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.
19
What is PSLE Aggregate Score?
It is a sum of scores.
What are these scores?
Are they raw scores?
20
The PSLE Aggregate Score
Takes into account the performance of pupils in all 4 subjects
Allows pupils to be ranked fairly 21
Can raw scores be used?
NO !
22
Why Not?
Different subjects have different levels of difficulty
So are the spread of marks from the average mark, i.e. the standard deviation (spread = standard deviation) 23

Sarah scores 85% in both EL and MT Her performance in MT is very close to that of other pupils 85% She did much better in EL as compared to other pupils EL MT

26
A need for standardisation of the raw scores Transformed Score or T-Score
27
85% EL ave = 60 T-Score ave = 80 MT 85% 50 T-Score converts average mark of each subject to a common score of 50 points. It also converts other marks taking into consideration the extent to which they differ from the average and the size of spread of the marks around the average 28
What is T-Score?
It gives the relative position of a pupil’s performance as compared to the performance of all the other pupils in that subject
The raw mark obtained in the exam only shows how good the pupil is in that subject, not how good he is as compared to others 29
How is T-Score calculated for each subject?
T
=
50
+
10 ( X Z Y ) where X: pupil’s mark for the subject Y: average mark (mean) scored by all pupils Z: spread of marks around the average mark (standard deviation) 30
Example:
Pupil’s mark (X) in exam = 50.0
Average mark (Y) scored by all pupils = 68.0
Spread of marks (Z) around the average mark (Y) = 14.0
T = 50 + 10 (50 - 68.0) 14.0
= 37.14 31
How is the Aggregate Score calculated?
By adding the T-Scores of the 4 subjects 32
Example: Subject Total EL1 200 CL2 Maths Science 200 100 100 Mark 105 152 67 58 T-Score 34 51 53 47 Aggregate: 185 33
Finally, all pupils are ranked according to their Aggregate Scores 34
T-SCORES & GRADES: Is it possible for a pupil with 3A* and 1A to be ranked lower than another pupil who has only 1A* and 3As?
Yes, it is possible 35
