Why and how are CUET-UG scores normalised? UGC chief explains
Common University Entrance Test (CUET)-UG is evaluated using equi-percentile method and the marks reflected in the score card are normalised scores, according to UGC chief M Jagadesh Kumar. The results for CUET-UG, the gateway for undergraduate admissions to over 200 universities across the country, were announced on Saturday.
«What is important to note that CUET-UG has been conducted over a period of 6 weeks with tests in a given subject held on different days. So naturally the question that arises is how are we going to compare the performance of different students on a common scale since they have written the test in the same subject but on different days.
»We need to ensure that the admissions are made based on a score that accurately compares the performance of the students," Kumar said. Asked why normalisation is done for CUET-UG and not all entrance exams, he said unlike CUET-UG, other entrance examinations are limited to fewer subjects.
«In single session entrance tests, one common statistically established method is to transform the raw marks into a common uniform scale using the percentile method so that the performance of students can be compared to each other. »But in entrance tests such CUET-UG since the test is conducted on different days and in multiple sessions for the same subject, it will give rise to multiple percentiles for each group of students.
In addition to the above difficulty another problem with using only percentiles is that in subjects such as Sports or Fine Arts, some weightage is given to the skill component by some universities," he said. «But, addition of raw marks in the skill component and the remaining weightage (75 pc) of percentile cannot be done to prepare the rank list because it
