JEE Main 2019 Percentile Score
The NTA (National Testing Agency), which is the conducting authority of JEE Main has prescribed the JEE Main percentile and normalization process. The process of normalization which is based on percentile calculation has been adopted by NTA to determine JEE Main 2019 results and rank list.
There are some key terms to understand before knowing how NTA will calculate JEE Main 2019 Percentile Score through the Normalization Process.
Key Terminology | What they mean |
Percentile/ Percentile Score | The score based on the relative performance of candidates who have appeared for the exam, is considered to be Percentile Score. While calculating a percentile score, the marks scored are converted into a scale ranging from 100 to 0 for each session of examinees. |
Normalization | The practice of comparing candidate scores across multi-session papers. NTA shall use the percentile equivalence, for normalization across sections. |
Highest Raw Score & Percentile Score | For every respective session, all the highest raw scores will have normalized Percentile Score of 100. This applies to that the highest raw scores secured by candidates would be normalized to 100 Percentile Score for their respective session. |
Lowest Raw Score & Percentile Score | The percentile score will depend on the total number of candidates who have taken the examination for their respective session. Percentile Score of all the lowest raw scores is different. |
The formula given below is used by NTA to calculate the Total percentile (T1P) score of a candidate:-
To help the students understand, here’s an example:
The JEE Main was conducted in four sessions:
- Session-1: Day-1 Shift-1
- Session-2: Day-1 Shift-2
- Session-3: Day-2 Shift-1
- Session-4: Day-2 Shift-2
The test takers for JEE Main were distributed in the following manner:
Distribution of candidates | ||||
Session | Day/Shift | No of Candidates
Absent Appeared Total |
Marks
Highest Lowest |
|
Session-1 | Day-1 Shift-1 | 3974 28012 31986 | 335 | -39 |
Session-2 | Day-1 Shift-2 | 6189 32541 38730 | 346 | -38 |
Session-3 | Day-2 Shift-1 | 6036 41326 47362 | 331 | -49 |
Session-4 | Day-2 Shift-2 | 9074 40603 49677 | 332 | -44 |
Total(Session-1 to Session-4) | 25273 142482 167755 | 346 | -49 |
In the above example, the method to calculate the Highest Raw Score in each paper will be normalized to 100, indicating that 100% of candidates have obtained scores that are equal to or lesser than the highest scorer/ topper for that session.
Example for: Highest Raw Score and Percentile Score
Session | Total Candidates Appeared | Highest Raw Score | Candidates who scored EQUAL OR LESS THAN Highest Raw Score | Percentile Score |
Session-1 | 28012 | 335 | 28012 | 100.0000000
[(28012/28012)*100] |
Session-2 | 32541 | 346 | 32541 | 100.0000000
[(32541/32541)*100] |
Session-3 | 41326 | 331 | 41326 | 100.0000000
[(41326/41326)*100] |
Session-4 | 40603 | 332 | 40603 | 100.0000000
[(40603/40603)*100] |
Example for: Lowest Raw Score and Percentile Score
Session |
Total Candidates Appeared | Lowest Raw Score | Candidates who scored EQUAL OR LESS THAN Lowest Raw Score | Percentile Score |
Session-1 | 28012 | -39 | 1 | 0.0035699
[(1/28012)*100] |
Session-2 | 32541 | -38 | 1 | 0.0030730
[(1/32541)*100] |
Session-3 | 41326 | -49 | 1 | 0.0024198
[(1/41326)*100] |
