CBSE OSM 2026: Class 12 Board Exams to Adopt Digital On-Screen Marking System

The Central Board of Secondary Education (CBSE) is set to implement a Digital Evaluation System for the 2026 Class 12 Board Examinations through On-Screen Marking (OSM). The shift marks a major transition from physical answer sheet checking to a fully digitized evaluation process aimed at improving accuracy, security, and efficiency.
The move will impact over 1.5 million Class 12 students and thousands of evaluators across India.
What is CBSE On-Screen Marking (OSM)?
On-Screen Marking (OSM) is a computerized evaluation method where physical answer sheets are scanned and assessed digitally by examiners.
Instead of checking physical copies manually, teachers will evaluate scanned answer scripts through a secure online portal.
How It Works:–
- Scanning of Answer Sheets: Physical copies are digitized at designated scanning centers.
- Identity Masking: Student details are hidden to ensure unbiased marking.
- Digital Allocation: Answer scripts are distributed online to authorized evaluators.
- On-Screen Evaluation: Teachers assess responses using digital marking tools.
- Automated Totalling: The system calculates marks automatically to eliminate totalling errors.

CBSE OSM 2026: Step-by-Step Evaluation Process
The digital workflow for Class 12 evaluation will follow these stages:-
- Collection & Digitization: Exam copies are sent to regional hubs for scanning.
- Secure Upload: Encrypted files are uploaded to the CBSE evaluation portal.
- Evaluator Authentication: Teachers log in through secure credentials (OASIS-linked).
- Mark Entry: Marks are awarded as per the official CBSE marking scheme.
- Review & Moderation: Senior examiners can conduct blind re-evaluation if required.
This system is designed to reduce manual errors and improve result processing speed.
Technical Requirements for Evaluation Centres
CBSE has outlined technical infrastructure guidelines for schools designated as evaluation centres (subject to final official updates):-
- Operating System: Windows 8.1 or above
- RAM: Minimum 4GB
- Internet Speed: Minimum 2 Mbps stable connection
- Static Public IP Address
- Updated Browsers & PDF Reader
- Power Backup: Mandatory UPS/Inverter system
Schools lacking stable connectivity may face implementation challenges during the initial phase.
CBSE Digital Evaluation 2026: Benefits and Challenges
| Feature | The Benefit (Pros) | The Challenge (Cons) |
| Accuracy | Auto-totalling removes human errors in calculation. | Technical glitches or slow servers can stall progress. |
| Speed | Digital allocation allows for faster result processing. | Screen Fatigue: Long hours can cause eye strain for teachers. |
| Security | Minimal risk of physical loss or damage to scripts. | Infrastructure gaps in rural or resource-poor schools. |
| Logistics | Massive savings on transport and physical storage. | Initial learning curve for non-tech-savvy examiners. |
Will CBSE Class 10 Also Shift to OSM in 2026?
As per current indications, the 2026 rollout is expected to apply only to Class 12 Board Exams.
Class 10 evaluation is likely to continue in physical mode until the digital system stabilizes.
Impact on Students: What Should Class 12 Candidates Know?
The marking criteria and CBSE syllabus remain unchanged.
However, students should ensure:–
- Clear and legible handwriting
- Use of dark blue or black pen
- Writing within prescribed answer booklet margins
- Avoid using light ink or faint pencil
Since answer sheets will be scanned, clarity of writing becomes important.
Expert Insight on CBSE OSM 2026
Education experts view the move as a significant step toward improving transparency and data integrity in board exam evaluation.
One of the recurring issues in past years has been manual totaling mistakes, leading to re-verification applications. The automated system is expected to address this concern.
However, experts also caution that scanning quality and infrastructure readiness will be critical for smooth implementation.
Frequently Asked Questions (FAQs)
1. Will computers check the answer sheets?
A:- No. Human examiners will evaluate answers. The system only assists with digital display, totalling, and secure data transmission.
2. Can students apply for revaluation under OSM?
A:- Yes. Revaluation and verification processes are expected to continue, potentially becoming faster due to digital record availability.
3. What happens if internet connectivity fails during evaluation?
A:- Evaluation centres are required to maintain backup connectivity and power systems. The portal generally includes auto-save functionality.
4. Is OSM confirmed for all subjects?
A:- CBSE is expected to implement it subject-wise as per official rollout guidelines.
Conclusion
CBSE’s introduction of On-Screen Marking (OSM) for Class 12 Board Exams 2026 represents a structural transformation in India’s board examination system. While the digital shift promises improved accuracy, faster processing, and enhanced security, its success will depend on technical readiness and smooth execution at evaluation centres nationwide.
Students and schools are advised to stay updated through official CBSE notifications for detailed implementation guidelines.
