Eligibility criteria for appearing in JEE (Advanced) are:

• Candidates should rank among the top candidates in Paper-1 of JEE (Main), broken down per category. For example, for JEE (Advanced) 2019 the top 245,000 were eligible, but only 46.5% of those were open for all, the rest being reserved for special categories.
• Candidates should be less than 25 years of age, with five year relaxation for SC, ST, and PwD candidates. ( The decision for this criteria is yet to finalized for JEE Advanced 2020)
• Candidates can attempt examination at most two times in two consecutive years.
• Candidates should have qualified the Class XII Board Examination (or equivalent) in the previous year.
• Candidates should not have accepted admission in any of the IIT earlier.

In addition, candidates are required to either be within the category-wise top 20 percentile of successful candidates in the Class XII Board Examination, or secure a 75% mark (65% for SC, ST and PwD).
