The formula adopted to convert JEE Main examinees’ board marks into a nationally comparable score for the purpose of Admissions to Engineering Colleges (NITS, IIIts and other top Colleges accepting JEE Main Scores) has been accused of favouring CBSE students over those from state boards, reports the Telegraph
During selections to the National Institutes of Technology, a candidate’s board score receives a 40 per cent weightage and their JEE Main score a 60 per cent weightage. Since all state boards are not equally generous in awarding marks, a method has been worked out to award a nationally comparable “normalised” score to each candidate.
However, several mathematicians have argued that this method, which ties a candidate’s normalised board score to how well students from their board have performed in the JEE Main, is potentially unfair.
The idea behind the adopted formula is to use the JEE Main itself as a standard to compare the various boards against one another.
It was found that if a CBSE student and another from any state board had the same board percentile rank and identical JEE Main marks, the CBSE student would have ended up with a higher final score.
The formula was worked out by a committee made up by CBSE chairman Vineet Joshi, NIT Delhi director Sandeep Sancheti, IIT Kanpur teacher Dheeraj Sanghi and a few experts from the Indian Statistical Institute, Calcutta.
CBSE chairperson Joshi said the formula was decided as “the middle path” between two others that were proposed. “This is the best possible formula,” he said.
