What JoSAA Does

JoSAA is India's centralized seat allocation system for engineering admissions to government-funded technical institutes. Before JoSAA (pre-2015), IITs had their own separate counselling called JAB (Joint Admission Board), while NITs, IIITs, and GFTIs used CSAB. Students had to manage two completely separate processes, registration, and payment systems.

JoSAA unified everything. Now, a candidate with both JEE Main and JEE Advanced ranks can fill choices for ALL institutes — IITs, NITs, IIITs, and GFTIs — in a single choice list on a single portal. The algorithm handles everything in 5 rounds over ~40 days.

Key features of JoSAA:

  • 100% merit-based — rank is the only criterion
  • Transparent algorithm (variant of Gale-Shapley deferred acceptance)
  • 5 rounds with Float/Freeze/Slide options for optimization
  • Single portal for all 113+ institutes
  • Single seat acceptance fee covering all institutes

1
What does JoSAA stand for?
JoSAA stands for Joint Seat Allocation Authority. The 'joint' refers to the fact that it jointly manages seat allocation across both IITs (which use JEE Advanced for admission) and NITs/IIITs/GFTIs (which use JEE Main). Before JoSAA, IITs conducted their own counselling (called JAB) separately from NITs (which used CSAB). JoSAA unified both into a single platform starting 2015.
2
Who runs JoSAA?
JoSAA is operated jointly by the Joint Admission Board (JAB) of the IITs and the Central Seat Allocation Board (CSAB) for NITs/IIITs/GFTIs. The official portal is josaa.nic.in. A different IIT hosts the JoSAA chairmanship each year on a rotating basis. The Ministry of Education provides overarching oversight.
3
When did JoSAA start?
JoSAA was first implemented in 2015, replacing the earlier separate systems — JAB counselling for IITs and CSAB counselling for NITs. The introduction of JoSAA was a major reform that allowed candidates to appear in a single unified counselling process instead of managing two separate registrations and choice filling exercises.
4
Can I participate in both JoSAA and state counselling?
Yes — you can participate in both JoSAA and state counselling simultaneously. Many candidates keep their JoSAA allotment as a backup while also registering for their state's engineering counselling (UPTAC, TANCET, KCET, etc.). If you get a better option in state counselling, you can decline your JoSAA seat and report to the state-allotted college instead.
5
Is there any cost to register for JoSAA?
JoSAA registration itself is free. You only pay money when you accept a seat — the seat acceptance fee of Rs.45,000 (General/OBC/EWS) or Rs.20,000 (SC/ST/PwD). This fee is part of the total institute fee and is adjusted against the final admission fee when you report to the institute.
