The Central Board of Secondary Education (CBSE) has announced that Class 12 answer copies will be evaluated through On-Screen Marking (OSM). It will start with the 2026 board examinations. The decision, notified on February 9, 2026, is aimed at improving accuracy, speeding up evaluation, and bringing greater transparency to the assessment process.CBSE conducts Class 10 and Class 12 board examinations for nearly 46 lakh students across India and 26 countries every year. Given the scale of the operation, the Board has described the digital evaluation system as a step towards streamlining one of the most critical stages of the examination cycle. Class 10 answer books, however, will continue to be checked in physical mode for now.
What is on-screen marking?
Under the new system, Class 12 answer sheets will first be scanned after the examination. Examiners will then assess the digitised copies on a computer screen instead of marking physical scripts.Teachers will log into a secure platform, evaluate answers, and award marks digitally. The software will automatically calculate the marks, reducing the risk of calculation errors. Students will continue to write their exams in pen-and-paper format. Only the evaluation process is changing.
Why has CBSE taken this step?
The Board has mentioned several concerns associated with manual checking, especially totalling errors and logistical challenges. When lakhs of answer sheets are handled physically, even minor human errors can impact final scores.Through OSM, CBSE aims to:
- Bring to an end totalling errors.
- Reduce manual intervention
- Accelerate the checking procedure.
- Reduce transportation time and cost.
- Reduced manpower to check.
- Facilitate broader involvement of teachers such as those in affiliate schools in foreign countries.
- Encourage the environmental friendliness system.
The Board has also indicated that verification of marks after results may not be required in the same way, since totals will be automatically generated.
What does it mean for Class 12 students?
For students, the biggest takeaway is improved accuracy. Since marks will be calculated by the system, the chances of arithmetic errors are expected to drop significantly. This could minimise the requests for re-totalling of the results declared.The accelerated evaluation system might also result in the acceleration of the results processing, but CBSE has yet to announce the change in the timeline of results.Notably, the syllabus and pattern of the question paper or examination form remain the same. Students will continue to write and prepare their exams.Nonetheless, digital marking may introduce more consistency in marking. As the scripts are revised on a centralised platform, they could be monitored and stabilised with time.
Why only Class 12 for now?
Class 12 board results play a decisive role in university admissions in India and abroad. Introducing digital evaluation at this level suggests that CBSE is prioritising accuracy where academic stakes are highest. Class 10 evaluations will continue in physical mode, possibly as part of a phased implementation strategy.
Are schools prepared?
CBSE has instructed schools to ensure technical readiness. Institutions must provide:
- A computer lab with Public Static IP
- Systems running Windows 8 or above
- Minimum 4 GB RAM
- Updated browsers
- Adobe Reader installation
- Reliable internet with at least 2 Mbps speed
Uninterrupted power supply
Teachers with OASIS IDs will be allowed to access the platform for familiarisation. The Board will conduct dry runs and training sessions, and a call centre will be established to resolve technical issues. Instructional videos will also be released.
A new phase in board evaluation
The introduction of on-screen marking marks a structural reform in how Class 12 answer sheets are assessed. While students may not see any visible change inside the examination hall, the backend of the system is being redesigned.If implemented smoothly, the digital evaluation model could reshape the board assessment process in the coming years, with accuracy, speed, and transparency at its core.
