Overview
The CSAB Special Round is a post-JoSAA counselling process conducted by the Central Seat Allocation Board (CSAB) to fill seats that remain vacant in the NIT+ system — NITs, IIITs, IIEST Shibpur, SPAs, and GFTIs - after all rounds of JoSAA have concluded. It typically runs as two separate rounds, commonly called Special Round-I and Special Round-II, and represents the last centralised opportunity for JEE Main-qualified candidates to secure a seat in this specific group of institutes for that admission cycle.
CSAB Special Rounds begin only once JoSAA's entire process is fully complete, generally in late July or early August, and are coordinated each year by a designated institute announced closer to the registration window.
Type
This is a centralised, government-run engineering seat allocation process conducted after JoSAA.
It exclusively covers the NIT+ system - NITs, IIITs, SPAs, IIEST Shibpur, and GFTIs.
Allotment is based on each candidate's JEE Main rank, since JEE Advanced and AAT scores are not used in CSAB.
Institutes Covered
CSAB Special Rounds fill vacant seats across roughly 31 NITs, 26 IIITs, and approximately 45 GFTIs.
IIT programmes are not part of CSAB under any circumstance — IIT seats are allocated exclusively through JoSAA.
SPAs (Schools of Planning and Architecture, including Delhi, Bhopal, and Vijayawada) and IIEST Shibpur also participate in CSAB Special Rounds for their applicable programmes.
Provider
CSAB is coordinated each year by a designated institute, announced closer to the registration window for that cycle.
The Board publishes the official brochure, schedule, and seat matrix on its portal, csab.nic.in, typically about a week before registration opens.
CSAB retains the same Home State (50%) / Other State (50%) quota structure used in JoSAA for NIT seats.
Key Details: Dates and Process
Registration, fee payment, and choice filling for CSAB Special Rounds typically open in late July, around 10:00 AM on the opening date.
Saved but unlocked choices auto-lock at a fixed date and time (commonly around a week after registration opens) if not manually locked earlier by the candidate.
All registered candidates must submit entirely fresh choices - any choices submitted during JoSAA are considered null and void and are not carried forward.
CSAB displays all academic programs across NITs, IIEST, IIITs, and GFTIs for which a candidate is eligible, regardless of tentative vacancy status at the time of choice filling.
The Special Round Enrolment Fee (SREF) is typically around ₹40,000 for General/OBC-NCL/EWS candidates and ₹19,000 for SC/ST/PwD candidates.
CSAB cutoffs are generally less competitive (higher in rank number) than JoSAA's final round closing ranks for the same college and branch, since CSAB fills the seats JoSAA couldn't.
Key Eligibility for CSAB Special Rounds
Candidates who were eligible for the NIT+ system in JoSAA based on their JEE Main rank, but did not register for JoSAA at all, can register fresh directly in CSAB.
Candidates who registered in JoSAA but were not allotted any seat by the final round remain eligible.
Candidates who already secured an NIT+ seat in JoSAA and paid the Partial Admission Fee can still participate if they want to try for a better branch or college, though fresh choices are still mandatory.
Candidates whose JoSAA seat was cancelled - due to document errors, non-payment of fees, or voluntary withdrawal/early exit - also remain eligible.
Candidates who are not Indian nationals and not OCI/PIO holders are not eligible for CSAB seat allocation.
What to Do Now
Confirm which eligibility category applies to your specific situation — unregistered, unallotted, or already holding a JoSAA seat — before assuming CSAB automatically applies to you.
Prepare an entirely fresh CSAB choice list, since your JoSAA preferences and registration do not carry over in any form.
If you already hold a JoSAA seat, understand clearly that accepting a new CSAB allotment permanently cancels your existing JoSAA seat, with no way to revert.
Save your choices frequently during the CSAB choice-filling window rather than waiting until the final day, and don't rely solely on the auto-lock feature as your safety net.
Before finalizing your CSAB preferences, comparing previous years' CSAB opening and closing rank trends against JoSAA's final round data can help you build a realistic, well-balanced choice list.
Key Things to Remember
CSAB Special Rounds fill vacant seats in the NIT+ system (NITs, IIITs, SPAs, IIEST Shibpur, GFTIs) after JoSAA fully concludes — IITs are never part of CSAB.
Registration typically opens in late July, with fresh choices mandatory for every candidate, including those already holding a JoSAA seat.
The Special Round Enrolment Fee is around ₹40,000 (General/OBC-NCL/EWS) or ₹19,000 (SC/ST/PwD).
Accepting a CSAB seat while holding a JoSAA seat permanently cancels that earlier JoSAA allotment.
