Admission Process

  • Entire counselling process will be conducted online. There is no need for the candidates to visit any IISER in-person during the counselling process.
  • Candidates can check if they received admission offers by logging into their application portal.
  • Admission offers to any candidate will be given strictly based on the following factors:
    • seat availability at each IISER in the current allocation round,
    • IAT rank obtained by the candidate OR JEE/KVPY rank (as applicable),
    • IISER preferences given by the candidate, and
    • the category to which the the candidate belongs.
  • If a candidate receives an admission offer, he/she can either choose to accept the seat OR reject it. If candidate rejects the offered seat or if no action is taken by the candidate before the deadline, then candidate will not be able to participate in further rounds of counselling.
  • If a candidate receives an offer, then to accept the seat offered, the student must pay a seat acceptance fee through online mode before the prescribed deadline. If the seat acceptance fee is not paid, the candidate will not be considered for admission in subsequent allocation rounds.
  • After accepting the offer and paying seat acceptance fee, the candidate can exercise two options:
    • candidate can FREEZE the seat (they will not participate in further rounds of counselling),
    • candidate can FLOAT (they will participate in further rounds of counselling to get their higher preferences). The FLOAT option is activated by default for those who pay the seat acceptance fee.
  • A student who has chosen to FLOAT will be again considered for seat allocation in the next round. If they are eligible to secure a seat in an IISER that is higher in their preference list than the currently accepted one, they will be offered that seat.
  • If seats in preferred IISERs are filled, then candidate will not be considered in further rounds of counselling. For example, if a candidate had given only two preferences as IISER-X and IISER-Y, and if the seats in these IISERs are filled, then the candidate will not be considered for seat allocation anymore. This process happens even if the student has not been allocated any seat in previous counselling rounds.
  • Admission offers given are provisional. They will be confirmed only after the candidates report at the IISER where they have secured admission and provide all the required documents in original.
  • Requests for extension of date or time for seat acceptance will not be entertained under any circumstances. Published deadlines will be strictly followed.
  • All the announcements related to the admission process will appear on this website. Candidates must follow this website for any updates.

Seat Acceptance Fee (SAF)

  • Seat Acceptance Fee is to be paid only after an offer of admission has been made to the candidate.
  • Rs. 35,000/- (Rs.25,000/- + Rs. 10,000/- (Non refundable administrative fee)) for General/EWS/OBC-NCL categories
  • Rs.17,500/- (Rs.12,500/- + Rs. 5000/- (Non refundable administrative fee)) for SC/ST categories.
  • Failure to deposit the SAF within the stipulated time will result in the cancellation of the offer. Furthermore, you will not be considered in any subsequent rounds of seat allotment during admission 2023
  • Once you register in your allotted IISER, this amount will be adjusted against your first semester fee.

Withdrawal Process

  • The application fee is not refundable.
  • Refund policy for the Seat Acceptance Fee is given below :
    • The candidate can withdraw his/her seat/offer by pressing the button “WITHDRAW OFFER” in the application portal. No other form/method of withdrawal is accepted. Email or phone communication in this regard is not entertained.
    • Once candidate has withdrawn, he/she will not be considered for further rounds of admission process. A withdrawn candidate cannot re-enter the admission process again under any circumstances.
    • There are two important withdrawal dates :
      • Round-wise withdrawal (RW) date, and
      • Final withdrawal (FW) date.
      • RW and FW dates will be announced in the admission website.
    • If a candidate withdraws from the counselling process before RW deadline, then no cancellation fee will be applicable.
    • If a candidate withdraws after the RW deadline, but on or before FW, then the non-refundable amount will be deducted.
    • IISERs and JAC are not liable for losses incurred if your application is not withdrawn in the above manner and on or before the stipulated date and time.
    • Once a candidate has withdrawn the offer through the counselling portal, the amount due will be returned through the same channel (credit/debit card, bank account etc.) used to pay the SAF. Such candidates do not have to take any additional steps towards their SAF refund. Refund process will start only after three weeks of the completion of the admission process.
    • If the candidate does not withdraw on or before FW deadline, then the SAF will be transferred to the allotted IISER. Any further withdrawal will be taken care by that particular IISER following the instructions given below.
    • If the candidate fails to join in-person at the offered IISER on the joining date mentioned in the offer letter of the respective IISER, the cancellation fee decided by the concerned IISER will be applicable.
    • Further, candidate who have paid SAF but fail to show up by the last date of admission fee payment at the concerned IISER will not be considered for further rounds of admission.
    • If the candidate decides to discontinue after joining any particular IISER, the refund policy of that IISER will be applicable.

The Seat Acceptance Fee will be eventually transferred to the IISER which the candidate finally registers at, and the respective IISER will collect the remainder of the fees that may be applicable locally from the candidate upon registration at the particular IISER.

Important last dates for withdrawal

  • Coming soon

Please Note

  • Requests for extension of last date for withdrawal will NOT be entertained.
  • For withdrawals before round-wise deadline, entire SAF will be refunded in full.
  • For withdrawals after round-wise deadline but before final withdrawal date Rs. 10,000.00 (Rs. 5,000.00 for SC/ST,PWD and KM) will be deducted. Rest of the SAF will be refunded.
  • For withdrawals after the final withdrawal date, withdrawal and refund rules of admitting IISER will apply.
