PSLE T-Score is the transformed score of each subject. It is based on raw scores, mean & standard deviation (SD).

T-score provides us with the relative position of a student’s performance as compared to the performance of all of the other students in the same level of a subject.

Score of each student will be transformed into a T-score and the PSLE aggregate score will be the sum of the T-scores of all 4 subjects instead of the student's scores.
