The one-time correction window for Joint CSIR-UGC NET December 2026 is open from 10 November to 12 November 2026, up to 11:50 PM. You cannot change your uploaded photograph or signature in it, so a wrong image cannot be fixed now.
What can you change in the CSIR NET form correction?
NTA's public notice of 10 November 2026 lists the editable fields in Annexure I. Everything else stays as submitted.

Why the photo and signature are locked
The notice puts both on its "shall NOT be allowed to change" list, next to mobile number, email and address. It gives no reason, and it offers no replacement route.
The common mistake is to wait for the correction window to fix a blurred or oversized image. That does not work. Check what you uploaded against the sizes in our CSIR NET application upload guide.
If your photo or signature is wrong, the notice offers no route to replace it. Write to NTA at csirnet@nta.ac.in or call 011-40759000 / 011-69227700, and keep your application number ready. We cannot promise what NTA will say.
Which name field can you correct?
Only one of three: your name, your father's name or your mother's name. If more than one is wrong, you must pick one, so check all three before you edit.
Match the spelling to your Aadhaar or marksheet, whichever you used while filling the form. A small spelling gap is the typical reason an admit card and an ID are questioned at the centre.
Fee after correction
A final correction counts only after you pay any additional fee. If a change in category or PwBD alters the fee, you pay the extra amount, and NTA says excess payment is not refunded. Pay through credit card, debit card, net banking or UPI.
The notice says a correction that needs extra fee takes effect only after that payment succeeds. Do not close the page after pressing submit until the payment page confirms.
Steps to correct your form
- Log in at csirnet.nta.nic.in with your application number and password.
- Open the application and check every field against your certificates.
- Edit only the permitted fields, then preview the form once more.
- Pay the extra fee if the portal asks, then submit before 11:50 PM on 12 November.
Once you submit, the form is frozen. There is no second correction.
Is the CSIR NET form still open, or was the deadline extended?
New applications are closed. NTA's notice of 5 November 2026 extended the last date for the online application form and the exam fee to 9 November 2026, up to 11:50 PM. The correction window then opens on 10 November, so it only helps candidates who already submitted a form.
The 10 November notice says the correction facility is one-time and that NTA will entertain no correction after 12 November 2026, 11:50 PM, under any circumstances. Keep checking csirnet.nta.nic.in and nta.ac.in for updates.
Which exam is this: CSIR NET or UGC NET?
This notice is for the Joint CSIR-UGC NET December 2026, a computer-based test for Junior Research Fellowship and Assistant Professor, Assistant Professor and Ph.D. admission, or Ph.D. admission only, in Indian universities and colleges. UGC NET has its own, separate window, which we cover in the guide linked at the end.
Live photo, HOD attestation and DigiLocker problems
The correction notice does not cover any of these. It does not offer a way to redo a live photo, and it mentions no attestation form. For a failing live capture, a missing document or a DigiLocker error, check the Information Bulletin on csirnet.nta.nic.in or contact NTA on the numbers above.
