Candidates who spotted a mistake in their CSIR-UGC NET December 2026 application have three days to fix it. The National Testing Agency opened the correction window today, November 10, and it closes at 11:50 pm on Thursday, November 12.

The window is a one-time chance. Once a candidate submits the corrected form, NTA freezes it, and no further changes are accepted at any stage. The three days are the last opportunity to correct anything before the computer-based exam on December 19, 22 and 27.

The December cycle decides eligibility for Junior Research Fellowship, Assistant Professor posts and PhD admission in five science subjects. Registration closed on November 9, after NTA moved the last date from November 5 and dropped the late fee. NTA said 2,36,656 candidates had registered by November 6, and 1,98,479 of them had paid the examination fee.

What you can change

Most of the form can be edited. Candidates can change their name, mother’s name or father’s name, though only one of those three. Date of birth, gender, category, sub-category and Persons with Benchmark Disabilities status are also open for correction. Academic details from graduation and postgraduation can be updated, along with the opted subject, the scanned photograph and signature, and the choice of exam cities. Up to four exam cities can be picked.

A photo or signature that was rejected, a misspelt name, or a wrong subject choice can all be fixed in this window. Our admission documents checklist covers the photo and signature specifications exam portals commonly ask for, which helps avoid a second rejection of an uploaded file.

What stays locked

Four fields cannot be touched: the registered mobile number, the registered email address, and the permanent and present residential addresses. Candidates whose error sits in one of those fields will not be able to fix it in this window. The NTA helpdesk can be reached on 011-40759000 or 011-69227700, or by email at csirnet@nta.ac.in.

How to make the correction

1. Visit the official CSIR NET portal and open the Joint CSIR UGC NET December 2026 correction window link.
2. Log in with the application number, password and security pin.
3. Edit the permitted fields and review every entry before moving on.
4. Pay any balance fee if a change, such as a category correction, alters the amount due.
5. Submit the corrected form and download the updated confirmation page.

Changing the category can change the fee, so the portal may ask for the balance amount before the form can be submitted. The payment has to be completed first. An unpaid correction does not count as submitted.

After November 12

The exam runs in computer-based mode on December 19, 22 and 27. Candidates should download the confirmation page after submitting the correction and keep a copy, since it is the only proof the changes went through. Anything still wrong in the form after November 12 stays wrong, so the review step before submission is the one to take slowly.
