The merit list for admission to engineering colleges through JEE (Main) will be based on percentile scores and not on raw marks scored by aspirants in test in a two-cycle computer-based examination system from 2019. As the formats for engineering courses have changed with tests to be held in January and April, NTA now announced a new process for arriving at NTA score, which will ultimately be the basis of the final merit list for admitting to IITs.
According to a senior official of HRD ministry, a group of experts from IITs (Roorkee, Kanpur, Delhi, Guwahati), IIM Lucknow, UGC, IASRI (Pusa) and AIIMS, Delhi, along with others have been referred for finalising the process for calculating the NTA scores. He also said that normalization procedure based on percentile score to reach NTA score is based on the format in practice for UG-MBBS test conducted by AIIMS, Delhi.
JEE (Main) aspirants from 2019, will have the choice of taking the test twice (January and April). The format will see the test conducted over a period of around 14 days in each cycle with multiple sessions each day, a device that is intended to reduce the prospects of cheating and manipulation.
NTA official, while explaining the format said, “Each candidate will get different sets of questions per session and efforts will be made to maintain equivalence among various question papers, the difficulty level of papers in different sessions may not be same completely.” The percentile score of each session will be based on the relative performance of students in that particular shift and hence, the percentile scores for each session will be considered at par. This could result in some candidates ending up attempting a tougher set of questions and are likely to get lower marks. But for sure, ‘normalisation procedure based on percentile score’ will be used in such a way that candidates are neither benefitted or disadvantaged due to the difficulty level of examination.
NTA score will be calculated in multiple sets. It means, the topper of each session gets the same percentile of 100 and marks obtained in between highest and lowest scores are converted into appropriate percentiles. Apart from the overall percentile, subject-wise percentile scores will also be calculated. To reduce tied scores, the percentile scores will be calculated up to seven decimal places.
In the end, all percentile scores of the different session will be merged in one list and overall merit will be based on percentile score in descending order. In case two candidates obtain equal percentile, the interse (among themselves) merit will be decided in order of candidates obtaining higher percentile score in mathematics, physics, chemistry and finally the candidate older in age. If still there is a tie, the candidates will be conferred joint rank.
This whole process is divided into three steps – distribution of examinees in the sessions randomly so that each session gets the equal number of candidates, preparation of results for each session and compilation of the NTA score and preparation of the overall merit list.
