Question: How to calculate T Score and composite Score of a candidate in Aptitude Test?

Answer: Norms and standards as laid down from time to time shall be applied uniformly to all candidates for adjudging their suitability. The cut-off for Tests are fixed on the basis of Normalized T-score. The Mean of normalized T-score is 50 and its SD is 10. The basic parameters required to calculate T-score are Mean and Standard Deviation calculated from normalized sample. The range of the T-score is 20 to 80.

The formula to calculate T-score is:

The T-score for dummy subject for a test can be calculated as follows:

Dummy subject score on Test 1 = 20

Mean of Test 1 on normative sample = 14

SD of Test 1 on normative sample = 3

Calculation of composite score is as follows

As weightage to aptitude test is 30, the composite score of a dummy subject can be calculated as follows:

Composite T-score of a candidate having 5 tests in a battery is = 300

The max T-score a candidate can obtain having 5 tests in a battery is (80×5) = 400.

The composite score out of 30 is :

* Out of 400 score candidate scored = 300

* Out of 30 score will be =
