CSAB 2026 Vacant Seats After JoSAA Round 5: NITs & IIITs with the Highest Seat Availability

Key Takeaway

With JoSAA Round 5 completed, the focus now shifts to CSAB Special Rounds, where vacant seats in NITs, IIITs, and GFTIs are offered to eligible JEE Main candidates. Although the official institute-wise vacancy matrix will be released by CSAB before registration opens, historical trends indicate that several institutes consistently witness seat movement after JoSAA due to withdrawals, upgrades, and non-reporting.

Why Do Seats Become Vacant After JoSAA Round 5?

Many candidates accept seats in JoSAA but later withdraw, upgrade to another institute, or opt for private universities or state counselling. As a result, a considerable number of seats remain unfilled and are transferred to CSAB Special Rounds, giving students another opportunity to secure admission in NITs and IIITs. 

NITs & IIITs Expected to Have Better Seat Availability

OGcollege Insight: The official vacant seat matrix will be published by CSAB after JoSAA counselling concludes. Actual vacancies depend on withdrawals, reporting status, and institute-wise seat movement. 

Instead of waiting for the official vacancy list, start preparing your preference list now. The OGcollege CSAB College Predictor helps estimate colleges available at your JEE Main rank using previous CSAB cutoffs. Once you've shortlisted institutes, the OGcollege CSAB Choice Filling Tool prepares a data-backed preference order, while the OGcollege Talk to Seniors feature lets you connect with students from NITs and IIITs before making your final decision.

Which Branches Usually See More Vacancies?

While Computer Science Engineering remains the most competitive branch, previous CSAB rounds have shown comparatively better seat movement in branches such as Mechanical Engineering, Civil Engineering, Chemical Engineering, Metallurgical Engineering, Biotechnology, Production Engineering, and selected Electrical branches. Even in top institutes, occasional vacancies arise in ECE and EE because of candidate upgrades, though these remain limited.

When Will the Official Vacancy List Be Released?

CSAB is expected to publish the official institute-wise and branch-wise vacant seat matrix before the start of CSAB registration. Candidates should rely on the official seat matrix while filling their choices instead of depending only on expected trends. The CSAB 2026 schedule indicates that vacancies will be displayed before registration begins.

Talk to Seniors Before Filling Your Choices

Vacant seats only indicate admission opportunities—they don't explain placement quality, campus life, coding culture, internships, or hostel facilities. Through the OGcollege Talk to Seniors feature, you can interact with students currently studying at various NITs and IIITs to understand the actual academic environment before finalizing your CSAB preference list.

Conclusion

CSAB Special Rounds provide a valuable second opportunity for candidates who couldn't secure their preferred institute through JoSAA. Although the official vacancy list is still awaited, previous trends suggest that several NITs and IIITs will again have meaningful seat movement after Round 5. Prepare your preference list in advance, analyse previous cutoff trends, and update it once the official CSAB vacancy matrix is released.
