The IISER Joint Admissions Committee (JAC) will release the IAT 2026 cutoffs round-wise on iiseradmission.in alongside the seat allotment results.

The IISER 2026 cutoffs (Opening and Closing Ranks) are typically released across 8 to 9 rounds of counseling. As the counseling progresses from Round 1 to the final rounds, the closing ranks generally increase, making it easier to secure a seat in later stages.

The IISER 2026 cutoff acts as the final gatekeeper for admission. It is the specific closing rank or minimum score that determines whether you qualify for a seat at your preferred campus.

  • If your rank is under 1,500 (General Category), you are in a strong position to secure a seat in top campuses like IISER Pune, IISER Kolkata, or IISER Mohali during Round 1.
  • If your rank is 4,000+, you can secure seats at IISER Tirupati or IISER Berhampur in later rounds (typically Round 4 onwards).
  • Based on 2025 data, the General category ranks between 1 and approx. 4,500 across all 7 campuses and multiple rounds.
  • Expect the 2026 closing ranks to follow these ranges, potentially stretching even higher as students withdraw to join IITs or medical colleges.

With approximately 70,000 candidates competing for just 2,363 seats in 2025, the IAT saw a highly competitive 3.3% success rate, with intake ranging from 400 seats at IISER Tirupati to an exclusive 288 at IISER Pune.

IISER Cutoff 2026: College-wise Seat Intake

Seat intake remains largely stable year-on-year, so this serves as the most accurate reference for IISER 2026 counselling.

IISER Campus BS–MS (Dual Degree) Seats BS/B/Tech Seats Total Campus Intake
IISER Berhampur 300 – 300
IISER Bhopal 300 – 475
IISER Kolkata 310 – 310
IISERMohali 275 – 275
IISER Pune 288 – 288

IISER Tirupati 250 50* 300
Total 2,043 225 2,268
IISER Cutoff 2026: College-wise Seat Intake

Ques. How does the seat intake affect the cutoff for IISER Pune and Mohali?

Ans. IISER Mohali (275 seats) and IISER Pune (288 seats) have the lowest seat intakes among the established campuses. Because these two campuses are highly preferred by toppers but have fewer available slots, they consistently maintain the highest cutoffs (lowest opening and closing ranks) in the counseling rounds.

Ques. What is the total number of seats available through the IAT 2026?

Ans. For the 2026 cycle, there are a total of 2,268 seats across all seven campuses. Roughly 90% of these are dedicated to the BS-MS Dual Degree (2,043 seats), while the remaining 10% (225 seats) are for specialized BS or B.Tech degrees.

IISER Cutoff 2026: Good Score

The IAT is conducted for a total of 240 marks (60 marks each in Physics, Chemistry, Mathematics, and Biology). A “good score” depends on your target IISER campus, category, and preferred program (BS-MS, BS in Economic Sciences, B.Tech, etc.).

  • For the General (UR) category, 140 – 150+ marks is considered a safe score for top campuses like IISER Pune and Kolkata (Safe for top campuses: 160+).
  • Similarly, for OBC-NCL, 125 to 135+ marks is considered to be the safe score
  • For EWS, 130 – 140+ marks
  • For SC 80 – 95+ marks, and
  • For ST 70 – 85+ marks.
Score Range (Out of 240) Expected Rank Range (Approx.) Admission Scope
180+ Top 200 Very High chances of admission in IISER Pune/Kolkata
160–179 200–600 High Chances of admission in IISER Mohali/Bhopal.
140–159 600–1500 Safe score for IISER TVM/Tirupati
120–139 1500–3000+ Moderately good for IISER Berhampur & later rounds
Below 110 3000+ Low chances in mainly later rounds or reserved seats

Note: For highly competitive programs like IISER Pune BS-MS, IISER Kolkata BS-MS, or IISER Kolkata Computational & Data Sciences, General category students should ideally target 160–180+ marks to stay safe in early rounds.

Advice for IAT Aspirants

  • Aim 15–20 marks higher than the previous year’s perceived cutoff to account for uncertainty and competition.
  • A score of 150+ is generally considered a strong & safe score for most General category students to get at least one IISER seat.

Ques. How should I distribute my marks across the four subjects to reach a safe total?

Ans. The IAT consists of 60 marks per subject (15 questions each). To reach a total of 150+, you don't necessarily need to be a master of all four. Most successful candidates aim for:

  • Strong Subjects (2): 45–50 marks each.
  • Average Subject (1): 30–35 marks.
  • Weak Subject (1): 15–20 marks.

Ques. What is considered a "Good Score" for SC/ST and OBC-NCL candidates?

Ans. For reserved category candidates, the good score cab be:

  • OBC-NCL/EWS: A score of 130–140+ is considered very strong and can grant access to mid-tier campuses like Mohali or Bhopal.
  • SC/ST: The threshold for a "good" score drops to 80–95+. Candidates scoring in this range often secure seats in the early counseling rounds, while those near 70 might have to wait for later rounds or newer campuses like Berhampur.

IISER Cutoff 2026: Mark vs Rank (Expected)

Since IAT 2026 is yet to be conducted, the Marks vs Rank data for IISER admissions 2026 is purely expected and based on the trends observed in IAT 2024 and IAT 2025.

The IAT is scored out of 240 marks (60 marks each in Physics, Chemistry, Mathematics, and Biology). The final rank depends on overall performance distribution, normalisation, and the total number of candidates.

Score Range General OBC EWS SC ST Admission Chances
190+ 1–150 1–100 1–120 1–50 1–30 Excellent chances in IISER Pune/Kolkata
170–189 150–700 100–500 120–600 50–200 30–120 Very High chances in Pune, Kolkata, Mohali
150–169 700–1800 500–1200 600–1500 200–500 120–300 Good score for Mohali Bhopali, TVM
130–149 1800–4000 1200–2800 1500–3200 500–1000 300–600 Moderate chances of admission in TVM, Tirupati, Berhampur (early rounds)
110–129 4000–8000+ 2800–5500 3200–6000 1000–2000 600–1200 Possible in later rounds or newer campuses
Below 110 8000+ 5500+ 6000+ 2000+ 1200+ Low chances of admission in any of the 7 campuses

FAQs

Ques. An IAT candidate on Reddit is asking, “Is 100 a good score for IISER Mohali? In 2026 ?”

Ans. No,100 marks is generally not a "good" score for IISER Mohali in 2026 for a General category student. For IISER Mohali, a "good" score is now considered 140–145+. At 100 marks, a General candidate is likely looking at a rank beyond 5,000, which usually only makes them eligible for the very last rounds of the newer campuses (Berhampur or Tirupati).

Ques. What are the expected closing ranks for IISER Berhampur, Tirupati, and TVM in 2026?

Ans. Expected closing ranks for 2026 range from 3,500–6,500 for TVM, 4,500–8,000 for Tirupati, and 5,500–9,000 for Berhampur. Generally, a score between 110 and 135 is required to stay safe for these campuses during the final counseling rounds.

Ques. If I get a 1106 general category rank in IAT. Can I get into IISER Kolkata?

Ans. With a rank of 1106, your chances for IISER Kolkata are borderline but possible, as closing ranks typically hover between 900 and 1200 by the later rounds.

Ques. If I score 58 marks in the IAT 2026 as an SC candidate. Is any IISER possible for these marks?

Ans. For an SC candidate, scoring 58 marks in the IAT is a "on-the-fence" situation. While this score might have been more comfortable in previous years, the rank inflation seen in 2024 and 2025 has moved the goalposts for 2026. For a guaranteed seat in the early rounds at any IISER, SC candidates usually need 75–85+ marks.

Ques. Which IISER has the lowest cutoff?

Ans. IISER Berhampur, IISER Tirupati, and sometimes IISER Thiruvananthapuram tend to have lower closing ranks compared to older, more popular campuses like Pune, Kolkata, or Bhopal, offering higher chances of admission with a lower score.

Ques. Can I get IISER with 14,000 marks?

Ans. Yes, you have a solid chance of getting into newer IISERs (such as Berhampur, Tirupati, or Mohali) with a 14,000 general rank, especially in later counseling rounds.
