IISER IAT Counselling 2026 Important Dates

What is IISER IAT Counselling?

The IISER Admissions Portal conducts a centralized counselling process for admissions into the BS-MS Dual Degree programmes and selected four-year undergraduate programmes offered by the participating Indian Institutes of Science Education and Research (IISERs).

Seats are allotted according to:

• IAT 2026 All India Rank (AIR)
• Candidate’s category
• Reservation policy
• Campus preferences submitted during counselling
• Seat availability

IISER IAT Counselling Registration Process

Candidates can register online by following these steps:

Step 1: Login

Visit the official IISER Admissions Portal and log in using your:

• IAT User ID
• Password

Step 2: Complete Registration

Verify personal details and submit the counselling registration form.

Step 3: Choice Filling

Select your preferred IISER campuses and programmes in the order of preference.

You may choose among:

• IISER Pune
• IISER Kolkata
• IISER Mohali
• IISER Bhopal
• IISER Thiruvananthapuram
• IISER Tirupati
• IISER Berhampur

Candidates are advised to arrange their preferences carefully, as seat allotment depends heavily on the order of choices filled.

Step 4: Lock Choices

Review all selected preferences carefully before the deadline and lock your choices.

Once locked, no modifications will be allowed after the choice-filling window closes.

IISER IAT 2026 Seat Allotment Process

The Joint Admissions Committee will conduct multiple rounds of seat allotment.

Seat allocation depends on:

• All India Rank (AIR)
• Reservation category
• Availability of seats
• Candidate’s choice order

Candidates can download the allotment letter after each round through the admission portal.

Freeze and Float Options Explained

After receiving a seat, candidates must choose one of the following options:

Freeze

• Accept the allotted seat.
• Exit further counselling rounds.
• No further upgradation.

Float

• Accept the current seat.
• Continue participating in future rounds.
• Eligible for a higher preferred campus if a vacancy becomes available.

Choosing Float allows candidates to retain the currently allotted seat while remaining eligible for better preferences.

IISER IAT 2026 Seat Acceptance Fee (SAF)

Candidates allotted a seat must pay the Seat Acceptance Fee (SAF) within the specified deadline.

Important Notes

• The fee includes a non-refundable administrative component.
• The remaining amount is adjusted against the first-semester tuition fee after admission.
• Failure to pay the SAF within the deadline will lead to cancellation of the allotted seat.

Documents Required for IISER Counselling 2026

Candidates should keep scanned copies of the following documents ready:

• IAT 2026 Scorecard
• Rank Card
• Class 10 Marksheet
• Class 10 Passing Certificate
• Class 12 Marksheet
• Class 12 Passing Certificate
• Government-issued Photo Identity Proof
• Category Certificate (if applicable)
• OBC-NCL Certificate
• EWS Certificate
• SC/ST Certificate
• PwD Certificate (if applicable)

Ensure all uploaded documents are clear and in the prescribed format.

IISER IAT Counselling 2026: Key Strategies Every Candidate Should Know

To maximize your chances during IISER IAT 2026 counselling, candidates should carefully arrange their institute preferences and understand how the Float and Freeze options work. Since all IISERs follow a similar academic curriculum and research-focused education model, preference order should reflect your genuine choices rather than assumptions based on location or popularity.

Important Counselling Tips:

• Choose Preferences Carefully: Seat allotment is based on your preference list and rank. Always place your most preferred IISER at the top, even if your admission chances appear uncertain.
• Understand Float vs Freeze: If you receive a seat and wish to be considered for a higher-preference institute in later rounds, select the Float option and pay the Seat Acceptance Fee (SAF). Without paying the SAF, the allotted seat will be cancelled.
• Upgraded Seats Replace Previous Allotments: If you receive an upgraded seat while using the Float option, your earlier allotted seat is automatically forfeited and cannot be reclaimed.
• Keep All IISERs in Your Preference List: Avoid excluding institutes based only on location. All IISERs offer strong academic standards, quality faculty, and research opportunities, making every campus a valuable option.
• Upload Documents Carefully: Ensure all required documents, including Class 12 marksheets and valid category certificates (if applicable), are uploaded before the prescribed deadlines. Missing or incorrect documents can lead to cancellation of candidature.
• Explore Other IAT-Based Admissions: Candidates can also consider certain research-oriented programmes offered through IAT scores at institutes such as IIT Madras and IISc Bangalore, depending on the admission policy for the current academic session.

Following these strategies can help candidates make informed decisions and improve their chances of securing admission to their preferred IISER during the counselling process.

Common Mistakes That Students Make In Choice Filling- Explained

The “Cut-off Matching” Mistake

Students look at last year’s closing ranks and place institutes they think they will get at the top, rather than the institutes they actually want to attend.

The Example

Sneha’s rank is 1,200. Her dream is IISER Kolkata, but last year it closed at 900. She sees that IISER Mohali closed at 1,400. Afraid of losing a seat, she fills out her list like this:

1. IISER Mohali (Safe)
2. IISER Kolkata (Dream)

The Consequence

In Round 1, the system checks Choice #1 (Mohali) and immediately awards it to her. Because she received her top choice, Choice #2 (Kolkata) is permanently deleted. Even if Kolkata’s cut-off drops to 1,250 in later rounds, Sneha can never get it because the algorithm only allows you to move up your list, never down.

The Solution

Always place your dream college at #1, regardless of your rank.

1. IISER Kolkata (Dream)
2. IISER Mohali (Target)

The “Copy-Pasting Someone Else’s List” Mistake

Students blindly copy the preference order of internet influencers, coaching teachers, or high-scoring friends without looking at the actual programs offered.

The Example

Rahul wants to study Engineering Sciences (Data Science/Computer Science). He copies a standard topper’s list online:

1. IISER Pune
2. IISER Kolkata
3. IISER Mohali

The Consequence

He gets allocated IISER Pune. However, he discovers too late that IISER Pune only offers basic sciences (BS-MS), while IISER Bhopal is the one that offers the specialized BS Engineering Sciences program he actually wanted. He is now stuck studying pure sciences because he cannot change his preferences or move down his list.

The Solution

Research the specific academic tracks of each campus. If you want Engineering Sciences or Economic Sciences, IISER Bhopal must be placed at the top of your list, above Pune or Kolkata.

3. The “Incomplete List” Mistake

Students with borderline ranks only fill in their top 2 or 3 choices, leaving the rest of the list blank out of pride or overconfidence.

The Example

Aman has a borderline rank of 3,200. He only wants Pune or Mohali, so he fills out his form like this:

1. IISER Pune
2. IISER Mohali
   (Leaves choices 3 through 7 completely blank)

The Consequence

In Round 1 and Round 2, both Pune and Mohali fill up completely with higher-ranked students. Because Aman left the other options blank, the system gives him No Allotment. He is completely kicked out of the counselling ecosystem and gets zero seats, whereas he could have easily secured a seat at IISER Tirupati or Berhampur.

The Solution

Always fill out all 7 IISERs. Use the lower-cutoff IISERs at the bottom of your list (Positions 5, 6, and 7) as a vital safety net. You can always choose to “Float” later.

Summary Checklist for Choice Filling

• Rule 1: Order strictly by your personal preference, not by past cut-offs.
• Rule 2: Put your dream choice at #1, even if your rank is low.
• Rule 3: Fill in all available options to secure a safety net.
• Rule 4: Verify the specific courses (like Bhopal’s Engineering) before ranking them.

Admissions Beyond IISER Campuses

must separately apply through the respective institute’s admission portal, as these admissions are not conducted through the IISER counselling system.

With counselling registration beginning on July 2, 2026, candidates should complete registration, carefully fill their campus preferences, upload the required documents, and remain updated about the seat allotment schedule.

Timely registration, proper choice filling, and prompt payment of the Seat Acceptance Fee will ensure a smooth admission process into the desired IISER campus.
