Home State Quota Percentage at NITs — CSAB 2026

Since JoSAA's inception, NITs have followed a structural rule: approximately 50% of seats in each branch are reserved for candidates whose home state matches the state where the NIT is located, and the remaining 50% are open to candidates from all other states (Other State quota). This 50/50 split is a defining feature of NIT admissions and continues to apply in CSAB's Special Rounds, since CSAB is simply an extension of the same counselling framework for filling leftover seats.

Home state status is typically determined based on where a candidate completed their Class 11 and 12 schooling (or equivalent), rather than their family's permanent address or where they were born. Exceptions and special provisions exist — for example, for children of central government employees with transferable jobs, or for defence and paramilitary personnel — and the precise business rule is published fresh each counselling year, so always confirm your status during registration.

Because home state and other state seats are effectively separate competition pools, your realistic chances at your home-state NIT are usually meaningfully different — and often more favourable — than your chances at the same branch under other-state quota, or at an NIT outside your home state. This is especially relevant in CSAB, where seat vacancies are limited and every percentage point of competition matters.

When filling your CSAB choice list, always prioritize your home-state NIT's branches under home state quota near the top, since this pool typically has less competition. Combine this with category reservation — for example, an OBC-NCL candidate from the home state generally faces the smallest, least competitive pool: home-state OBC-NCL seats. See our related guide on OBC-NCL rank required at NITs for how these layers combine.

It's important not to assume this same 50/50 rule extends everywhere — most IIITs and GFTIs handle this differently. See our page on home state quota at IIITs and GFTIs for the accurate picture there.

In practice, the home/other state split and category-wise vertical reservation (General/CRL, OBC-NCL, SC, ST, EWS) operate together, creating distinct seat pools such as Home State-General, Home State-OBC-NCL, Other State-SC, and so on. This layered structure explains why closing ranks for what appears to be the "same" branch and institute can vary widely depending on which specific pool you fall into. Understanding your exact category — and keeping your category certificate valid and current — is essential to correctly interpreting cutoff data and choice filling.
