IIT Branch Change Rules Explained

What "branch change" means

Many IITs allow a limited number of students to change their branch (department) after the first year, based mainly on their first-year academic performance. It is a way for students who did very well in the first year to move into a different branch, subject to seats and rules.

How it generally works

While the precise policy differs between institutes, the common pattern is:

• Branch change is usually considered after the first year, based on first-year CGPA.
• A minimum CGPA threshold typically applies to be eligible to request a change.
• Changes are subject to seat availability and caps on how many can leave or join a branch.
• It is competitive — higher first-year performance improves your chances.

Rules vary by institute

Crucially, there is no single all-IIT branch-change rule. Each IIT sets its own eligibility criteria, CGPA cut-offs, seat limits, and procedure, and these are revised over time. Do not rely on another institute's policy or an old version — read the current academic regulations of the specific IIT you join.

A practical note for applicants

Because branch change is limited and competitive, it is safer to treat it as a possible bonus rather than a guaranteed plan. When filling JoSAA choices, list branches and institutes you would genuinely be content to study, instead of assuming you will switch later.
