The National Institute of Open Schooling (NIOS) has officially released the revised timetable for NIOS 10th and 12th Board Exams 2025 for students in Bihar. This updated date sheet has been issued specifically for those exams that were postponed due to the Bihar Assembly Elections 2025.
Earlier, some theory papers scheduled for November 6, 2025, had to be postponed across the state. Now, NIOS has released the new dates, ensuring students can prepare with clarity and avoid any confusion. As per the revised notification, the rescheduled exams for both Secondary (Class 10) and Senior Secondary (Class 12) will now be conducted on November 29, December 1, and December 2, 2025.
This article provides a complete, easy-to-read breakdown of the updated NIOS Bihar exam timetable, along with important instructions students must follow before appearing for the exam.
Why Was the NIOS Exam 2025 Rescheduled in Bihar?
The Bihar Assembly Elections 2025 were scheduled on the same day as some NIOS board exams. Conducting both events simultaneously could have caused logistical issues like:
-
Lack of proper exam centre availability
-
Human resource shortage for invigilation
-
Students facing difficulty reaching centres
-
Administrative challenges for state authorities
To avoid such complications, NIOS proactively shifted the exam dates. This ensures that:
-
Students can appear for the boards without stress
-
Election proceedings remain uninterrupted
-
Centres can operate smoothly
-
Exam environment remains safe and organised
The revised dates give students additional preparation time—something many candidates may find beneficial.
