CBSE On-Screen Marking 2026: All Class 12 scripts go digital
CBSE introduced On-Screen Marking (OSM) for Class 12 in 2026 . CBSE On-Screen Marking 2026 converts physical booklets into encrypted PDFs and ensures all Class 12 response scripts are assessed online by verified examiners.
How CBSE On-Screen Marking 2026 works
Physical answer booklets are collected at regional scanning centres and converted into high-resolution, secured PDF files using industrial high-speed scanners. These encrypted files are uploaded to a secure cloud portal where verified subject experts log in with special credentials to evaluate scripts.
The digital interface provides electronic marking tools so examiners can award points and annotate pages on-screen. The system enforces mandatory question validation, preventing submission if any question is left unmarked. Automated marks calculation sums scores digitally to remove human arithmetic errors.
CBSE On-Screen Marking 2026: safeguards and responsibilities
Only verified examiners with designated login credentials can access the portal. Chief Examiners monitor evaluator activity in real time via dashboards that show progress and adherence to marking norms. Regional centres are responsible for secure physical collection and high-speed scanning of answer booklets.
Encryption and secure cloud access are used throughout the workflow to protect scanned scripts. The digital system also logs examiner actions, and automated checks help maintain consistency across evaluations.
