IIT, NIT, IIM & Central Government Institutes — Admission, Locations and the Quota System

By Sampath Kumar · Updated 9 Sept 2026

India's centrally funded institutes run on a completely different set of rules from state counselling. There is no state merit list, the reservation is central rather than your state's, and for the IITs there is no home-state advantage at all. This page sets out how each family admits students, where every campus is, and exactly how the quota arithmetic works.

Which exam takes you where

Four different doors, and students routinely confuse them. Everything on the engineering side starts with JEE Main; only the IIT door needs a second exam behind it.

How IIT admission actually works

The 23 IITs admit to B.Tech, B.S., B.Arch and the dual-degree and integrated programmes purely on the JEE Advanced rank, through JoSAA. There is no state quota, no management quota and no donation seat — the entire intake is All India merit.

1. Sit JEE Main (Paper 1). Conducted by NTA, normally in two sessions in the first months of the year; your better session score counts.
2. Make the JEE Advanced cut. Only the top band of JEE Main rankers — of the order of 2.5 lakh candidates, distributed across categories — become eligible to register for JEE Advanced.
3. Sit JEE Advanced. Conducted by one of the IITs on rotation, usually in May. Two papers, both compulsory, on the same day.
4. Clear the Class 12 condition. An IIT seat also requires either about 75% aggregate in Class 12 (relaxed to roughly 65% for SC, ST and PwD candidates) or a place in the top 20 percentile of your own board. One of the two is enough — many students do not realise the percentile route exists.
5. Register for JoSAA and fill choices. One combined choice list covering IITs, NITs, IIITs and GFTIs. Order it by what you actually want, not by what you think you will get; the software protects you from being pushed down your own list.
6. Ride the rounds. JoSAA runs several rounds. Float, slide or freeze after each allotment, pay the seat acceptance fee and complete document verification within the window — miss it and the seat goes.
7. Report to the institute. Physical reporting and the final fee close the loop.

All 23 IITs, state-wise

Sorted by state so you can see the geography rather than the pecking order. Remember that for an IIT it makes no difference which state you are from.

How NIT, IIIT and GFTI admission works

The 31 NITs, the IIITs and the Government Funded Technical Institutes all admit on the JEE Main rank through the same JoSAA counselling as the IITs — one registration, one choice list, both families in it. What makes the NITs different is the home-state quota.

1. Sit JEE Main. Your best session score becomes your All India Rank.
2. Declare your home state correctly. For NIT seat allotment your home state is normally the state in which you passed Class 12 — not your birth state, and not where your family lives.
3. Fill JoSAA choices. The same combined list. Home-state and other-state options at the same NIT appear as separate choices.
4. Go through the JoSAA rounds, then CSAB special rounds if seats remain. CSAB covers the NIT+ system only — IIT seats never return to it.

How IIM admission works

The 21 IIMs admit to the two-year MBA / PGP on the strength of CAT plus a great deal else. A percentile alone decides nothing.

1. Hold a bachelor's degree (final-year students may apply), with the minimum aggregate the IIMs specify, relaxed for reserved categories.
2. Sit CAT, conducted by the IIMs on rotation, normally on a Sunday in late November.
3. Get shortlisted. Each IIM sets its own bar and its own formula — the CAT sectional and overall percentiles, but also Class 10, Class 12 and graduation marks, and academic and gender diversity.
4. Written test and personal interview. WAT or a group exercise, followed by the panel interview.
5. Final composite score. CAT, past academics, work experience, diversity and the interview are weighted together. This is why two candidates with the same percentile get different results.

Straight after Class 12 there is a second door: the five-year Integrated Programme in Management at a handful of IIMs, entered through IPMAT or JIPMAT rather than CAT.

Other central government institutes worth knowing

Beyond the IIT, NIT and IIM systems, the central government funds several institute families that students overlook simply because they do not know the entrance exam.

The quota system, in full

Every centrally funded institute — IIT, NIT, IIIT, GFTI, IIM alike — applies the same Government of India reservation. This is central reservation and it is not the same as your state's list, which is the single most expensive misunderstanding in the whole process.

Horizontal reservation, on top of the above

• PwD — 5%. Persons with benchmark disability, applied horizontally: the 5% is carved out within each category rather than added as a sixth category. So there are PwD seats inside Open, inside OBC-NCL, inside SC and so on.
• Female supernumerary seats in the IITs. The IITs create additional seats for women over and above the sanctioned intake, so filling them does not shrink the general pool. Category reservation applies within these seats too.
• Home state / other state in the NITs. Not a social category but a quota all the same, splitting each NIT's seats roughly in half. It does not exist in the IITs.

What the percentages mean in real seats

The arithmetic, so you can sanity-check any branch you are considering. A reserved-category candidate who clears the open cut-off is counted against Open, not against their category — which is why the effective number of category seats is usually a little better than the table suggests.

State-wise analytics: where the institutes actually are

75 IITs, NITs and IIMs across 31 states and union territories. Two things stand out. Every state has at least one NIT — that was the design — while the IITs and IIMs are far more unevenly spread. And a handful of states carry three or four of these institutes at once, which matters to you only through the NIT home-state quota, since IIT and IIM seats are All India.

The annual cycle, in months

Exact dates move every session and each body publishes its own calendar, so treat this as the shape of the year and confirm the day on the official portal.

Frequently asked questions

Where to verify all of this

Reservation percentages are Government of India norms applied by all centrally funded institutions. Process and eligibility follow the published rules of the conducting bodies — NTA for JEE Main, the organising IIT for JEE Advanced, JoSAA and CSAB for engineering seat allotment, and the IIMs for CAT. Institute lists are the campuses operating as of 2026-09-09. Because every one of these bodies republishes its brochure each session, confirm the current year's dates, cut-offs and certificate formats on the official portal — jeemain.nta.nic.in, jeeadv.ac.in, josaa.nic.in, csab.nic.in and iimcat.ac.in — before you act on anything here. College Path does not publish closing ranks for these institutes; JoSAA's own round-wise opening and closing rank file is the only authoritative source.
