CSAB Special Rounds 2025: Vacant Seats in Top NITs Announced
The CSAB has released the vacant seat matrix for its 2025 Special Rounds. Learn about the final day for choice-filling, key dates, and eligibility for a last chance at admission to top NITs.

Following the conclusion of the six rounds of JoSAA counselling, the Central Seat Allocation Board (CSAB) has released the provisional vacant seat matrix for the special rounds of counselling for 2025. This much-anticipated announcement opens a final opportunity for engineering aspirants to secure a seat in the country's top NITs, IIITs, IIEST, and other Centrally Funded Technical Institutions (GFTIs). The CSAB Special Rounds aim to fill the seats that remain vacant after the JoSAA process, giving thousands of students a last chance at admission.
The online registration and choice-filling process for the CSAB Special Rounds are underway, and today, August 7, 2025, is the final day for choice-filling and locking. The last saved choices will be auto-locked by the system at 8:00 PM IST today, so candidates are advised to finalize their preferences well in advance.
CSAB Special Round: A Lifeline for Aspirants
The CSAB Special Rounds are a critical phase for candidates who either did not get a seat in the JoSAA rounds, were dissatisfied with their allotment, or had their seat cancelled due to various reasons. Participation in these rounds requires a fresh registration and a non-refundable fee. The counselling process will take place over three rounds, with the first seat allotment result scheduled to be declared on August 9, 2025.
Key Vacancy Highlights
The released seat matrix provides a clear picture of the available seats across various institutions. While popular branches like Computer Science and Engineering (CSE), Electronics and Communication Engineering (ECE), and Mechanical Engineering have limited vacancies in the top-tier NITs, a significant number of seats are available in other core and emerging specializations.
A detailed analysis of the vacant seats shows openings in the following branches in some of the top NITs:
- NIT Trichy: Vacancies are mostly in less-sought-after branches such as Production and Chemical Engineering. A few seats may also be available in Civil Engineering.
- NIT Surathkal: Seats are available in branches like Mining, Metallurgy, and other core engineering disciplines.
- NIT Warangal: Vacancies are noted in Chemical, Civil, and Metallurgical Engineering.
- NIT Rourkela: A handful of seats are available across branches like Bio Technology, Mining, and Ceramic Engineering.
- Other NITs: Many other National Institutes of Technology have a substantial number of vacant seats, including in popular branches, especially in the female-only and PwD (Persons with Disabilities) categories.
Candidates should carefully review the seat matrix on the official CSAB website to identify colleges and courses where they have a strong chance of securing a seat based on their JEE Main rank.
How to Participate and What to Do Next
To participate in the CSAB Special Rounds, candidates must follow a specific set of steps:
- Fresh Registration: All candidates, regardless of their participation in JoSAA, must register anew on the CSAB portal. This includes paying the required Special Round Enrolment Fee (SREF).
- Choice Filling and Locking: Candidates must select their preferred colleges and courses from the available list. This process closes today.
- Seat Allotment: The provisional seat allotment for Round 1 will be published on August 9, 2025.
- Online Reporting: After the seat allotment, candidates who are happy with their seat must pay the Institute Admission Fee (IAF-II), upload documents, and complete online reporting between August 9 and August 12, 2025.
Eligibility for CSAB Special Rounds
All candidates with a valid JEE Main 2025 rank are eligible. This includes:
- Candidates who did not get any seat in the JoSAA rounds.
- Candidates who withdrew their seat from JoSAA.
- Candidates whose seats were cancelled in JoSAA due to document verification issues.
- Candidates who did not register for JoSAA but meet the eligibility criteria.
This final counselling opportunity is crucial for those who have been holding out for a seat in an NIT. The strategic selection of choices, based on the vacant seat matrix and previous years' cut-offs, will be key to a successful admission.
