Candidates should have been born on or after October 1, 1998. Five years age relaxation is given to SC, ST, and PwD candidates, i.e. these candidates should have been born on or after October 1, 1993.

A candidate can attempt JEE (Advanced) maximum of two times in two consecutive years.

A candidate should have appeared for the Class XII (or equivalent) examination for the first time in either 2022 or 2023 with Physics, Chemistry, and Mathematics as compulsory subjects.
Candidates who had appeared in Class XII (or equivalent) examination for the first time in 2021 or earlier, are NOT eligible to appear in JEE (Advanced) 2023, irrespective of the combination of subjects attempted/offered.
Note: By appearance in Class XII (or equivalent) examination, it is meant that the Board concerned declared the result for that year irrespective of whether or not examination was conducted. It will be considered as an appearance even if the result of a particular candidate got withheld.

However, if the examination Board of Class XII (or equivalent) declared the results for the academic year 2020-21 on or after October 25, 2021, then the candidates of that Board who appeared for their Class XII (or equivalent) examination in 2021 are also eligible to appear in JEE (Advanced) 2023, provided they meet all the other eligibility criteria. In case the examination Board of Class XII (or equivalent) declared the results for the academic year 2020-21 before October 25, 2021 but the result of a particular candidate was withheld, then the candidate will not be eligible to appear in JEE (Advanced) 2023.

A candidate should NOT have been admitted to an IIT irrespective of whether or not the candidate continued in the program OR accepted an IIT seat by reporting “online” / at a “reporting centre” in the past. Candidates whose admission to IITs was cancelled (for whatever reason) after joining any IIT are also NOT eligible to appear for JEE (Advanced) 2023.

Candidates who have been admitted to a preparatory course in any of the IITs for the first time in 2022 can appear in JEE (Advanced) 2023.

The candidates who were allocated a seat in an IIT through JoSAA 2022 but (i) did not report “online” / at any “reporting centre” OR, (ii) withdrew before the last round of seat allotment, OR, (iii) had their seat cancelled (for whatever reason) before the last round of seat allotment for IITs, are eligible to appear for JEE (Advanced) 2023.

However, in all of the above cases, the candidate is also required to fulfil the conditions mentioned from Criterion 1 to Criterion 4.
