The Central Board of Secondary Education (CBSE) has announced a major reform in the evaluation process by introducing On-Screen Marking (OSM) for Class 12 board examinations starting in 2026. The decision aims to enhance efficiency, transparency, speed, and accuracy in answer sheet evaluation. However, the Board has clarified that the evaluation of Class 10 answer books will continue in physical mode in 2026, as done previously.
CBSE conducts board examinations annually in India and 26 other countries, catering to nearly 46 lakh students. With this digital transition for Class 12, the Board seeks to streamline assessment and reduce manual errors.

What is On-Screen Marking (OSM)?
On-Screen Marking is a digital evaluation system where scanned answer sheets are assessed online by trained examiners. The system is designed to:
- Eliminate totalling errors
- Automate coordination processes

According to CBSE, OSM will also make post-result verification of marks unnecessary, thereby reducing manpower requirements.

To ensure smooth implementation, CBSE has directed schools to arrange the following infrastructure:
- Computer lab with public static IP
- Computers/Laptops with Windows 8 or above
- Minimum 4 GB RAM
- Updated internet browsers
- Adobe Reader installed
- Reliable internet connection (minimum 2 Mbps)
