IISER IAT 2026 Admission Process (Simple Explanation)
Admission to the Indian Institutes of Science Education and Research (IISER) is done only through the IISER Aptitude Test (IAT). Students who want to study at IISER must appear for this entrance exam.
The IAT 2026 exam will be conducted as a computer-based test on Sunday, 7 June 2026 at 9:00 AM. The exam will take place at different exam centres across India.
Counselling and Seat Allotment Process
After the exam is completed, the IAT results will be announced online. Only students who qualify in the exam will be allowed to participate in the online counselling process.
During counselling, candidates will need to select their preferred IISER institutes in the application portal. These preferences are not required during the initial application for the exam. They are filled only after the results are declared.
The entire counselling process will be conducted online, so students do not need to visit any IISER campus in person during the seat allocation stage.
Students can check whether they received an admission offer by logging in to their application portal.
How Seats Are Allotted
Admission offers are given based on several factors:
- Availability of seats in each IISER
- Rank obtained in the IAT 2026 exam
- Preferences of IISER selected by the candidate
- Category of the candidate (General, OBC, SC, ST, etc.)
Based on these factors, students may receive an admission offer for a particular IISER.
What to Do After Receiving an Admission Offer
If a candidate receives a seat offer, they have two choices:
- Accept the seat
- Reject the seat
If the candidate rejects the offer or does not take any action before the deadline, they will not be allowed to participate in further counselling rounds.
Seat Acceptance Fee
If a student wants to accept the offered seat, they must pay the Seat Acceptance Fee (SAF) online before the deadline.
The fee structure is:
General / EWS / OBC-NCL / PwD / KM categories
- ₹35,000 total
- ₹25,000 seat acceptance fee
- ₹10,000 non-refundable administrative fee
SC / ST categories
- ₹17,500 total
- ₹12,500 seat acceptance fee
- ₹5,000 non-refundable administrative fee
This fee must be paid only after receiving an admission offer.
If the fee is not paid before the deadline, the seat will be cancelled and the candidate will not be considered in further rounds.
Freeze and Float Options
After accepting a seat, candidates must choose one of the following options.
Freeze Option
If a student selects Freeze, it means:
- They accept the current IISER seat.
- They will not participate in further counselling rounds.
- Their admission will be finalized for that institute.
Float Option
If a student selects Float, it means:
- They accept the current seat temporarily.
- They will still participate in further counselling rounds.
- If a higher preferred IISER becomes available, they may get that seat.
However, if a student receives a better preference seat, the previously allotted seat will automatically be cancelled.
Important Rule for Every Counselling Round
Students must take action in every round of counselling.
In each round they must choose either:
- Float, or
- Freeze
If a candidate does not take any action in a round, their application will be treated as withdrawn and they will be removed from the counselling process. After that, they cannot return to the counselling process again.
Preference Selection and Seat Availability
Students should carefully choose their IISER preferences.
For example, if a candidate selects only two institutes and both institutes become full, then the student will not be considered for further seat allocation, even if they did not receive a seat earlier.
Final Admission Confirmation
All admission offers are provisional.
Final admission will be confirmed only after the candidate reports to the allotted IISER campus and submits the original documents for verification.
Important Instructions for Candidates
Candidates must ensure that all the information and documents submitted in the application are correct and genuine.
If at any stage it is found that:
- the information is incorrect, or
- the candidate does not meet eligibility criteria
then the admission will be cancelled immediately.
Also, requests for deadline extensions will not be accepted. Students must complete all steps before the official deadlines.
