The Central Seat Allocation Board (CSAB) conducts Special Rounds annually to fill vacant seats remaining across NITs, IIITs, Indian Institute of Engineering Science and Technology (IIEST) Shibpur, and other Government Funded Technical Institutions (GFTIs) following the conclusion of all JoSAA rounds. Unlike JoSAA, which covers both IITs and NIT+ system seats, CSAB Special Rounds exclusively cater to the NIT+ system using valid JEE Main 2026 ranks. Candidates who did not secure a seat in JoSAA, surrendered their JoSAA seat, or wish to upgrade to a better institute/branch must register fresh on the official CSAB portal (`csab.nic.in`).

CSAB cutoffs fluctuate significantly compared to JoSAA because seat availability depends on leftover vacancies. Follow these core guidelines when creating your preference list: * **Analyze the Vacant Seat Matrix PDF:** Prioritize institutes and branches that have actual non-zero vacancies in your category (OPEN, OBC-NCL, SC, ST, EWS). * **Retain Safety Choices:** If you already hold a JoSAA-confirmed seat, list ONLY those choices in CSAB that are strictly higher in priority than your current seat. * **Avoid Short Choice Lists:** Since choice locking is final and Round 2 is the absolute last allotment, add sufficient backup choices to prevent missing an allocation. * **Automatic Choice Locking:** System automatically locks your last saved choices upon deadline expiry.
Upon seat allocation in CSAB Special Round 1, candidates must select one of the following official options during online reporting.
| Option Selected | Meaning & Impact | Current Seat Status | Next Round Participation |
|---|---|---|---|
| Freeze | Accepts allotted seat & exits further allocation. | Confirmed | Exits CSAB (Proceed to Physical Reporting) |
| Float | Accepts seat, remains open to higher choices in ANY institute. | Retained as Fallback | Participates in Special Round 2 |
| Slide | Accepts seat, remains open to higher choices in SAME institute. | Retained as Fallback | Participates in Special Round 2 |
| Surrender & Participate | Rejects current seat completely, moves to Round 2 afresh. | Forfeited / Released | Participates in Special Round 2 without fallback |
After securing a seat in CSAB Special Round 1 or 2, candidates must report physically to the allotted institute with these original documents.

JoSAA conducts the main multi-round counselling for IITs, NITs, IIITs, and GFTIs. CSAB Special Rounds take place after JoSAA to fill leftover vacant seats specifically in the NIT+ system using valid JEE Main ranks.
No. If you accept and report to your JoSAA seat, it is retained as a fallback while participating in CSAB. It is only replaced if you are allocated a higher choice in CSAB or explicitly choose the 'Surrender & Participate' option.
Yes. If no seat is allocated in CSAB Special Rounds, your processing fee (minus standard administrative charges of ₹1,000–₹2,000) is refunded to the original bank account.
The official vacant seat matrix PDF is published on the CSAB portal (csab.nic.in) immediately after JoSAA counselling and reporting conclude.
Selecting 'Surrender & Participate' forfeits your allocated Round 1 seat, returning it to the pool. You then enter Round 2 competing strictly for higher preferences without a fallback seat.
