What is the last time to correct the CSIR NET December 2026 form?

11:50 PM on November 12, 2026. The correction window opened on November 10, and NTA has said this is a one-time chance, with no second window after the deadline.

Can I change my exam subject and exam city in the CSIR NET correction window?

Yes. NTA allows changes to the exam subject and all four exam city choices, along with date of birth, gender, category, and qualification details.

Do I have to pay extra to correct my CSIR NET form?

Only if your change affects the fee. A change in category or PwBD status that raises the fee means you pay the difference online. The extra fee is not refunded.

When is the CSIR NET December 2026 exam?

NTA will hold the computer-based test on December 19, 22, and 27, 2026. The city slip and admit card dates will be announced later on the official portal.

Tonight, 11:50 PM: CSIR NET December 2026 Correction Window Closes

The clock is ticking for CSIR NET December 2026 candidates. The National Testing Agency (NTA) will shut the application correction window tonight, November 12, at 11:50 PM. If your form has a wrong date of birth, a wrong subject, or a wrong exam city, this is your last chance to fix it. NTA has said plainly that no second chance will come after the deadline.

The correction window opened on November 10, after an NTA public notice the same day. It stays open for three days only. Candidates can make changes on the official CSIR NET portal. Once you submit the corrected form, it gets locked. You cannot open it again, so read every field twice before you hit submit.

CSIR NET December 2026 is the national test for the Junior Research Fellowship (JRF), Assistant Professor posts, and PhD admission. NTA runs it as a computer-based test. Applications for this cycle closed on November 9, and the exam will be held on December 19, 22, and 27, 2026. That is why tonight matters so much. A small error left in the form now can follow you all the way to the exam hall.

What you can still change before 11:50 PM

NTA has allowed changes to several fields in this window. You can correct your date of birth, gender, and category. You can also update your sub-category or PwBD status, as long as it has not been verified through the UDID portal.

Your study details are open for edits too. Graduation details and postgraduate qualification details can both be changed. So can your exam subject, which matters a lot, because the subject decides the paper you sit for in December.

City choice is another big one. You can change all four exam city preferences, but only within the limits of the permanent and present addresses you gave during registration. Pick cities you can actually reach on exam day.

Names work a little differently. You can change any one of these three: your name, your father’s name, or your mother’s name. NTA does not allow all three to be changed at the same time. If two of them are wrong, you will have to pick the one that matters most and fix that.

The fee catch: some changes cost extra money

Most corrections are free, but one type can cost you money. If you change your category or PwBD status and the new category carries a higher fee, you must pay the difference. The payment goes through credit card, debit card, net banking, or UPI.

Two things to keep in mind here. First, the corrected details take effect only after the extra payment goes through. Second, the extra fee will not be refunded, even if you later feel the change was not needed. So check the fee for your new category before you save the change, not after.

Check every field twice before you hit submit. After tonight, the form you have is the form you keep.

How to fix your form in 7 steps

Do this well before 11:50 PM. Portals slow down in the last hour as thousands of candidates log in at once, and a payment that fails at 11:55 PM may not get a second try.

Go to the official CSIR NET portal at csirnet.nta.nic.in.
Open the Joint CSIR-UGC NET December 2026 application correction link.
Log in with your application number and password.
Go through the form field by field and edit what needs fixing.
Review all the changes with care before you submit.
Pay the extra correction fee, if it applies to your change.
Submit the corrected form and download the confirmation page for your records.

Keep that confirmation page safe. It is your proof that the correction went through, and you may need it if any detail looks wrong later.

What happens after tonight

Once the window closes, the form is frozen. NTA will use the details on record for the city slip, the admit card, and the exam itself. The subject-wise schedule, exam city, and shift details will come through separate notices on the official portal.

The exam dates are already fixed: December 19, 22, and 27, 2026. The city intimation slip is expected in late November, and admit cards usually arrive about three days before each paper. The UGC NET December 2026 correction window followed a similar pattern earlier this month, and candidates there faced the same one-chance rule.

If you have already checked your form and everything is right, you do not need to do anything tonight. The correction window is only for candidates who need to fix something. But if you have even a small doubt about your subject, your city choices, or your date of birth, open the form now and check. Ten minutes tonight can save you months of trouble later. We will track the city slip and admit card dates in our education news section as NTA announces them.
