JoSAA Seat Matrix 2027: Overview & Key Highlights
The JoSAA Seat Matrix is the definitive master roster released annually by the Joint Seat Allocation Authority detailing the exact number of sanctioned seats available across every engineering branch, degree type (4-year B.Tech/B.S., 5-year Dual Degree B.Tech+M.Tech, 5-year Integrated M.Sc.), reservation category, and state quota.
In 2027, the total seat pool surpasses 59,500+ undergraduate seats, buoyed by the introduction of cutting-edge interdisciplinary specializations like Artificial Intelligence & Data Engineering, Robotics & Automation, Microelectronics & VLSI Design, and Sustainable Clean Energy.

| PwD (Persons with Disabilities) | 5% (Horizontal) | Minimum 40% benchmark disability across all categories (OPEN, EWS, OBC, SC, ST) |
Female Supernumerary Quota (FSQ) Explained
To balance gender diversity in technical education, the Ministry of Education mandates a minimum of 20% female enrollment across every undergraduate program in all 23 IITs and 32 NITs.
How Supernumerary Seats are Created
Female supernumerary seats are EXTRA seats added on top of existing capacities. They do NOT reduce or snatch seats from the open 'Gender-Neutral' pool.
Dual Opportunity for Girls
Female applicants are eligible for BOTH the Gender-Neutral seat pool (competing with all candidates) AND the exclusive Female-Only pool, providing superior closing rank cutoffs.
