In short
NTA's one-time correction window for Joint CSIR-UGC NET December 2026 is open 10-12 Nov (11:50 pm). What can and cannot be changed, and fees.
The National Testing Agency (NTA) has opened a one-time window for candidates to correct their Joint CSIR-UGC NET December 2026 application forms. Its public notice of 10 November 2026 says corrections can be made from 10 November to 12 November 2026, up to 11:50 pm, on csirnet.nta.nic.in. After that, NTA will not accept any correction under any circumstances.
Joint CSIR-UGC NET decides eligibility for Junior Research Fellowship, appointment as Assistant Professor and admission to PhD in Indian universities and colleges. The December 2026 test is a computer-based test.
What can and cannot be changed
Annexure I of the notice sets out the fields:
- Cannot be changed: mobile number, email address, permanent and present address, photograph and signature.
- Only one of these can be changed: candidate's name, father's name or mother's name.
- Any of these can be changed: date of birth, gender, category, sub-category or PwBD (if not verified through the UDID portal), graduation details, post-graduation details and subject.
- Exam cities: all four city preferences can be changed, based on the permanent and present address given at registration.
Fees and the one-time rule
If a correction raises the fee, for example a change of category or PwBD status, the candidate must pay the extra amount by credit or debit card, net banking or UPI, and the change takes effect only after that payment. Fees already paid are not refunded, even if the new fee is lower. Only one correction is allowed: once the changes are submitted, the form is frozen.
What to do now
Log in on csirnet.nta.nic.in, check every detail of your form and make any change before 11:50 pm on 12 November 2026, paying the extra fee if one applies. Make all changes at once, because there is no second chance. For queries, NTA's helpline is 011-40759000 or 011-69227700 and its email is csirnet@nta.ac.in. Exam dates, the city slip and admit card timing are on our CSIR NET December 2026 page.
