IISER Kolkata Cutoff 2026

Indian Institute of Science Education and Research Kolkata (IISER Kolkata), located at Mohanpur in Nadia district, West Bengal, admits students to its 5-year BS-MS Dual Degree programme through the IISER Aptitude Test (IAT). This page tracks the IISER Kolkata Cutoff 2026 — official dates, category-wise closing ranks, and previous years' trends — sourced from IISER's official admission channel.

Quick facts

• Sole admission route: IAT (IISER Aptitude Test) 2026. JEE Advanced and KVPY are discontinued as admission channels from the 2024–25 cycle onward — IAT rank is the only criterion.
• IAT 2026 was conducted on 7 June 2026 (confirmed on IISER Kolkata's official admission notice, iiserkol.ac.in).
• Admissions to all seven IISERs, including Kolkata, are administered centrally by IISER-JAC (Joint Admissions Committee) through the official portal iiseradmission.in.
• IISER Kolkata is a single BS-MS programme with no branch-wise cutoff — students pick a major (Biology, Chemistry, Mathematics, Physics, or Earth Sciences) in Year 2 or 3.
• As of 20 July 2026, the official Round 1 seat allotment and cutoff for IAT 2026 had not yet been published on iiseradmission.in. This page will be updated the same day it is released.

IISER Kolkata Cutoff: Previous Years' Closing Ranks (General Category)

The table below shows IISER Kolkata's final-round General category closing rank for the last three admission cycles, as recorded in IISER-JAC's official seat allotment records on iiseradmission.in.

2026 figures will be added to this table as each round's official allotment is published.

Reading the trend: IISER Kolkata's closing rank has widened each year as more students appear for IAT and campus awareness grows — a candidate ranked in the low thousands still had a realistic shot at Kolkata by the later rounds in 2025. Category-wise splits (EWS/OBC-NCL/SC/ST/PwD) are released separately for each round and will be added here once IAT 2026 Round 1 data is out.

How to Check the Official IISER Kolkata Cutoff 2026

1. Go to the official admissions portal: iiseradmission.in.
2. Log in with your IAT 2026 registered email ID and password.

4. Download the official PDF — it lists opening and closing ranks separately for each of the 7 IISER campuses and each category.
5. Locate the IISER Kolkata row and compare it against your category and All-India Rank.
6. Repeat after every round — closing ranks move as students float to higher-preference campuses.

Factors That Affect the IISER Kolkata Cutoff

• Number of IAT candidates: Roughly 1.86 lakh students appeared for IAT 2026, competing for 2,343 BS-MS seats across all seven IISERs — fewer than the ~2.5 lakh who appeared in 2025.
• Campus preference patterns: IISER Kolkata is among the older, more sought-after campuses (alongside Pune), so it typically closes at a tighter (lower) rank than newer campuses like Berhampur or Tirupati.
• Category-wise reservation: EWS, OBC-NCL, SC, ST, and PwD candidates are ranked on separate merit lists, so their closing ranks are consistently lower than the General category at the same round.
• Round number: Closing ranks rise through the counselling cycle as higher-ranked students float out to other campuses, opening seats for lower-ranked candidates in later rounds.
