The Indian Institutes of Science Education and Research (IISER) Berhampur started the IISER 2026 counselling registration process on July 2, 2026. Students who qualified in the IISER entrance exam can now register for counselling through the official website.
If you secured a rank in the IISER Aptitude Test (IAT) 2026, this guide will help you understand the complete counselling process, from registration to seat allotment.
When Does Registration Close?
The registration window stays open until July 9, 2026. You need to complete both registration and choice filling before this deadline. Missing the deadline means you will not be considered for admission to any IISER campus.
Step-by-Step Application Process
Follow these steps to register for IISER counselling 2026:
- Visit the official website at iiseradmission.in
- Click on the IAT 2026 Counselling registration link
- The counselling form will appear on your screen
- Complete your registration details
- Fill in your choice of institutes and courses
- Pay the counselling fees
- Review all details carefully
- Submit the form and save the confirmation page
Keep your IAT 2026 scorecard, Class 11 and 12 documents, category certificate (if applicable), and payment details ready before starting the registration process.
Available Seats at IISER Campuses
Here is the complete seat matrix for BS-MS programmes across all IISER campuses:
| IISER Campus | Total Seats |
|---|---|
| IISER Berhampur | 300 |
| IISER Bhopal | 300 |
| IISER Kolkata (BS-MS) | 280 |
| IISER Kolkata (Computational & Data Sciences) | 30 |
| IISER Mohali | 275 |
| IISER Pune | 288 |
| IISER Thiruvananthapuram | 320 |
| IISER Tirupati | 250 |
IISER Thiruvananthapuram offers the highest number of seats at 320, followed by IISER Berhampur and IISER Bhopal with 300 seats each.
Understanding the Choice Filling Process
Choice filling is a critical part of the counselling process. You need to arrange your institute and course preferences in the order you want them. The system will allot seats based on your IAT rank, seat availability, your preferences, and your category.
Think carefully before locking your choices. Once the choice filling window closes on July 9, you cannot make any changes.
What Rank Do You Need?
Your admission chances depend on the IISER campus you target. Here are the expected opening and closing ranks for top IISER institutes:
| IISER Campus | Expected Rank Range |
|---|---|
| IISER Pune | 10 to 717 |
| IISER Kolkata | 50 to 1801 |
| IISER Mohali | 100 to 2229 |
| IISER Bhopal | 150 to 2609 |
Students with a rank under 5000 have strong chances of getting admission to top IISER campuses. Ranks between 6000 and 9000 are considered safe for admission to newer IISER campuses.
For IISc Bangalore (which uses IAT scores but conducts its own counselling), you need a rank under 30 to have a realistic chance.
Important Points to Remember
The counselling process happens entirely online. You do not need to visit any IISER campus in person during counselling. However, make sure you use a laptop or desktop with the latest version of Chrome, Edge, or Firefox. Using a mobile phone is not recommended as it may cause technical issues.
Getting an IAT rank does not guarantee admission. Seat allotment depends on your rank, the availability of seats, your institute preferences, and your category. Students from SC/ST categories have better chances with lower ranks compared to general category students.
If you receive a seat allotment, you must download the seat allotment letter and pay the seat acceptance fee by the given deadline. Not paying the fee means your seat will be cancelled and offered to someone else.
Eligibility Requirements
Students who passed Class 12 in 2024, 2025, or 2026 can apply for IISER counselling, provided they have a valid IAT rank and meet all other eligibility conditions. You need to score 100+ marks in the IAT exam to qualify, though this cutoff varies by category.
Can You Withdraw from Counselling?
Yes, you can withdraw from the counselling process if you change your mind. Submit your withdrawal request through the official portal. Once you withdraw, you will not be considered for any further rounds of counselling.
What If You Face Technical Issues?
If the registration link does not work, this usually happens due to heavy traffic on the website or poor internet connectivity. Wait for a few hours and try again. Make sure you complete your registration well before the July 9 deadline to avoid last-minute technical problems.
Documents You Need
Keep these documents ready in scanned format before starting your registration:
- Class 10 certificate (for date of birth proof)
- Class 12 mark sheet
- Category certificate (if you belong to SC/ST/OBC category)
- Person with Disability (PwD) certificate (if applicable)
- Any other documents specified by the authority
The Complete Counselling Timeline
The IISER counselling process includes several stages. Registration and choice filling happen from July 2 to July 9. After the choice filling window closes, the authority will process all applications and announce seat allotments. Students who receive seat allotments need to pay the seat acceptance fee within the given time frame.
After fee payment, selected students will need to report to their allotted IISER campus and complete the admission formalities. The exact dates for seat allotment and reporting will be announced on the official website.
Does Early Registration Help?
No, registering early does not improve your chances of admission. IISER admission is based purely on your IAT rank and seat availability. However, registering early helps you avoid last-minute rush and technical issues.
Make sure you read all instructions on the official website carefully before completing your registration. Double-check all the information you enter, especially your contact details and document uploads. Any mistakes can cause problems during the admission process.
