Comparison of two Normalization Procedures and implications for students

2
Normalization procedure 1 Get percentile (P) of a student on the basis of 5- subject aggregate scores in board. Determine the JEE-Main aggregate marks corresponding to percentile P at the All-India level. Regard this as the normalized board score of the student (B 1 ). Get JEE-Main aggregate marks (A 0 ) of the student. The composite marks used for drawing merit list is A 1 = 0.6 A B 1.

3
Normalization procedure 2 Get percentile (P) of a student on the basis of 5-subject aggregate scores in board. Determine the JEE-Main aggregate marks corresponding to percentile P from the set of aggregate marks obtained by different students of that board in JEE-Main. Regard this as the normalized board score of the student (B 2 ). Get JEE-Main aggregate marks (A 0 ) of the student. The composite marks used for drawing merit list is A 2 = 0.6 A B 2.

P0 <= 50 50> P0 <=75 Distance of P1 And P2 From P0 for different Percentile Ranges of P0 The Difference of P2-P0 gives more stable results across the boards compared to P1-P0, which deviates from the P0 as high as 15 >15% of Student moved from Lowest Scoring group to higher Scoring groups Almost 10% of Student moved from this group to either higher Scoring Groups or Lower Scoring Group
