JoSAA Counselling 2027 Guide: Process, Rounds, Choice Filling & Seat Allotment

What is JoSAA?

The Joint Seat Allocation Authority (JoSAA) conducts common counselling for admission to all IITs, NITs, IIITs and GFTIs — over 60,000 seats — based on JEE Main and JEE Advanced ranks. It typically runs from June to July, right after JEE Advanced results.

The JoSAA Process, Step by Step

• Registration on josaa.nic.in with your JEE credentials.
• Choice filling: list institute + branch combinations in your true preference order. Fill generously — 60+ choices is normal.
• Mock seat allotments (usually two): see where your current choices would land you, then reorder.
• Choice locking before the deadline; unlocked choices auto-lock.
• Seat allotment rounds (five in recent years): each round allots the best available choice for your rank.
• Online reporting: pay the seat acceptance fee and upload documents within the window, every round you hold a seat.

Freeze, Float or Slide?

Choose Float if any higher preference remains anywhere; Slide if you're set on the institute; Freeze only when you've got your genuine first preference.

Choice Filling Strategy

• Order by your genuine preference, not by last year's closing ranks — the algorithm protects you from 'wasting' a choice.
• Study opening/closing ranks of the previous two years for realistic anchoring, but include a few ambitious choices above them.
• Decide the branch-vs-institute question before choice filling, not during allotment panic.
• Keep documents (Class 10/12 certificates, category certificate, photographs, JEE scorecards) scanned and ready before rounds begin.
