Since the exam officials are yet to announce the IISER 2025 counselling dates and details. However based on the previous year trends, there will be six rounds of IAT 2025 seat allotment process.
Following the previous years trend, IISER has the tendency of releasing multiple round of IAT seat allotment/ closing rank list, depending upon the availability of the seat in the IISER insitutes.
Candidates can go through the following information :
- If a candidate receives an admission offer, he/she can either choose to accept the seat or reject it. If a candidate rejects the offered seat or if no action is taken by the candidate before the deadline, then the 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),
- Candidates 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 considered for seat allocation againin 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.
