Important Update – Exam City Change Option for April 2026 NPTEL Exams

Dear Candidate,

We would like to inform you about an important update regarding the upcoming election dates and their potential impact on the April 2026 NPTEL exam schedule.

The current NPTEL exam dates remain unchanged and will be conducted as previously scheduled. If you want to change your exam city please read the mail below:

At present, none of the election dates clash with the scheduled exam dates. However, there is a possibility that additional exam dates may be scheduled if we are unable to secure sufficient colleges as exam centers due to election-related activities (for example, colleges being used as polling booths). If additional dates are scheduled, we will ensure that they do not conflict with election dates in your state.

We currently have more than 10 lakh learners registered for the April 2026 exams, and managing the logistics for such a large number of candidates is a significant task. We also understand that some of you may need to travel to your native places to participate in the voting process. Your academic progress and success remain our top priority, and we are committed to maintaining the integrity of the examination process.

To support this, we are providing a one-time option to change your exam city based on your travel plans for voting. We request that you also check with your colleges regarding any closure due to their use as polling booths and select your exam city accordingly.

Deadline to Change Exam City:
March 18, 2026 (Wednesday) 

Due to the very large number of candidates we handle, requests submitted after this deadline cannot be accommodated.

Exam City Change Option:

---

IF YOU ARE SATISFIED WITH THE EXAM CITY SELECTED DURING REGISTRATION FOR THE APRIL 2026 EXAM, YOU DO NOT NEED TO FILL THIS FORM.

---

You may log in to your exam registration dashboard to check your current exam city preference:
https://examform.nptel.ac.in/2026_01/exam_form/dashboard

Please read the following instructions before filling the form:

1. Use your exam-registered email ID to fill out the form.

2. The city change submitted through this form will be treated as final for the April 2026 NPTEL exam(s).

3. You may check the list of available states and cities for the April 2026 exams using the link below:
   https://docs.google.com/spreadsheets/d/e/2PACX-1vSo_KMr6yr5OIc1jiEEEta_j6AlH54CAm4gTPs5uydEUr_QDtNHta4hGqsY0IN-RI763T3pkEDxMVip/pubhtml

4. Last date to fill the form: March 18, 2026 (Wednesday)

CITY CHANGE FORM LINK:
https://internalapp.nptel.ac.in/B2C/exam_form/form.php

+++++++++++++++++++++++++++++++++++++++++++

Candidate data will be frozen after the deadline.
After this, requests for city changes will not be entertained.

We kindly request you to choose your exam city carefully so that you can both exercise your right to vote and fulfill your academic commitments.

Best regards,
NPTEL Team

Domain Certification

Domain Certification helps learners to gain expertise in a specific Area/Domain. This can be helpful for learners who wish to work in a particular area as part of their job or research or for those appearing for some competitive exam or becoming job ready or specializing in an area of study.

Every domain will comprise Core courses and Elective courses. Once a learner completes the requisite courses as per the mentioned criteria, you will receive a Domain Certificate showcasing your scores and the domain of expertise. Kindly refer to the following link for the list of courses available under each domain: https://nptel.ac.in/domains
