Home State Quota in JoSAA – How It Affects Your Chances

Every National Institute of Technology (NIT) reserves 50% of its seats for Home State (HS) candidates — those whose state of eligibility matches the NIT's state. The remaining 50% is under Other State (OS) quota, open to candidates from all states including the home state.

This means if you are from Tamil Nadu (state of eligibility = Tamil Nadu) and applying to NIT Trichy (located in Tamil Nadu), you compete in the HS pool — a much smaller and less competitive group. Your closing rank (the weakest rank that gets in) will be a higher number than the OS closing rank, meaning it is easier to qualify.

Important clarification: IITs have NO home state quota. All IIT seats are allocated under the All India (AI) quota only. Most IIITs also use AI quota, though a few have state-specific arrangements.

Your state of eligibility is based on the state of your Class 12 board as recorded in your JEE Main registration:

• If you studied under Tamil Nadu State Board → State of eligibility: Tamil Nadu
• If you studied at a CBSE school in Telangana → State of eligibility: Telangana (state where school is located, not CBSE headquarters)
• If you changed schools across states, the state of the school where you passed Class 12 is used
• It is set once at JEE Main registration and cannot be changed later

If you are genuinely eligible in two states (e.g., passed Class 10 in one state and Class 12 in another), only one state is assigned in JEE Main — whichever you entered at registration. Always double-check your JEE Main scorecard.
