NIOS Revised Exam Schedule 2025: Updated Dates for Class 10 & 12 After Postponement

The National Institute of Open Schooling (NIOS) has officially revised the exam timetable for its Secondary (Class 10) and Senior Secondary (Class 12) public examinations for the October–November 2025 session. Moreover, this update is important for all NIOS learners, as some papers were earlier postponed due to election-related arrangements and administrative requirements at several exam centres.

The new dates have been issued through Notification No. F-4/3/2025 (73/2025), dated 17 November 2025. Therefore, students should follow only the revised schedule now published on the official NIOS website.

📰 Why Were the Exams Rescheduled?

According to the official notifications issued by NIOS, certain examination centres were required for:

• Bihar Assembly Elections 2025, and

• Bye-election in Nuapada (Odisha)

Because of these events, many government school buildings and staff members were assigned to election duty, making it impossible to conduct exams on the original dates. Consequently, NIOS postponed the papers scheduled for 6 November 2025 and 11 November 2025.

To ensure fairness and smooth conduct, NIOS announced a new schedule for all affected subjects.

🗓 Revised NIOS Exam Dates (Updated & Official)

This updated schedule is based entirely on Notification 73/2025 (dated 17/11/2025). Students are advised to download the PDF from the NIOS portal for subject codes and complete details. Additionally, checking the official file helps avoid confusion.

For Bihar only, the revised date is 29 November 2025

Bihar and Nuapada (Odisha) centres will follow the new date of 1 December 2025

For all remaining centres across India, exams will be held on 2 December 2025

📌 Important Note

The subject names and timings listed above are taken exactly from the notification. However, students must confirm subject codes from the official PDF because NIOS uses numerical codes such as:

• Physics (312)

• History (315)

• Environmental Science (333)

• Library & Information Science (339)

• Painting (225)

Therefore, downloading the PDF avoids any misunderstanding.

• A fair and organized examination environment

Overall, this reflects NIOS’s commitment to transparency and student welfare.
