The directors of all the 15 IITs agreed to implement the new admission format of IIT-JEE from 2013 new eligibility criteria for 2013 under which successful candidates would have to be in the top 20 percentile of their respective boards to get a final rank in the IIT-JEE on Wednesday, 27th June 2012 by IIT council.
The new format for IIT-JEE 2013 does away with the existing eligibility criteria of 60% marks in boards.
Now, candidates will first appear for the JEE (main) screening test, which will filter out the top 1.5 lakh students for the JEE (advanced) test. The final IIT ranking would depend only on the all India rank in JEE (advanced), subject to the successful students meeting the percentile criteria.
The top 20 percentile will vary across boards from year to year. For example, those who got more than 78% in CBSE last year would have made it to its top 20 percentile bracket. For UP boards, students with more than 65% marks would have been eligible.
The new pattern was agreed by the IIT Council. HRD minister Kapil Sibal, chairman of the council.
The ALL India IIT Faculty team welcomed the new pattern
that giving weightage all state board exam marks.
