1. 📝 What Is CSAB Counselling?

The Central Seat Allocation Board (CSAB) conducts counselling to fill vacant seats in NITs, IIITs, GFTIs, and several other participating institutes after JoSAA rounds conclude. While JoSAA handles seat allocation including IITs, CSAB focuses exclusively on NIT+/NIT+—an umbrella that excludes IITs but often allows students to secure desirable branches in NITs/IIITs/GFTIs through three types of special allocation rounds:

• CSAB‑Special Rounds
• CSAB‑NEUT Rounds (for North‑East states & certain UTs)
• CSAB‑Supernumerary Rounds (for candidates from specific Union Territories)

In 2025, CSAB has also merged DASA with the Special rounds.

2. 🎯 Why Participate in CSAB Counselling?

Candidates who were either:

• Eligible in JoSAA but didn’t register or opted out,
• Registered but didn’t receive a seat,
• Received a seat but lost it due to non-payment or document issues,
• Exited deliberately from JoSAA,
• Paid initial fees but want to upgrade,

…can use CSAB as a second chance to secure or improve seats. It’s especially valuable when compared to JoSAA cutoffs—often more relaxed—giving access to branches and institutes that were previously out of reach.
