Parents’ Role in PSLE
• Know your child, communicate with
the teachers on child’s needs
• Over-stressing your child e.g. too
many tuition homework given
• Not communicating with your child
• Be supportive of your child
• Provide a conducive home learning
environment

PSLE Results are based not on
Raw scores but on T-Scores
T-Scores can vary from
year to year---Let’s talk

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)

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?
(X - Y)
=
+
T 50 10
Z
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

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
