CBSE has introduced On-Screen Marking (OSM) for Class 12 board exams starting 2026 to enhance evaluation efficiency and transparency.[1][2] This digital shift allows examiners to assess scanned answer sheets online, reducing manual errors and speeding up result processing.
## What is OSM?
On-Screen Marking involves digitizing physical answer booklets into scanned images for direct evaluation on secure digital platforms. Examiners use tools to mark responses, add comments, and tally scores automatically, eliminating totalling mistakes common in traditional methods.[1][6] Class 10 evaluations remain in physical mode for 2026.
## Key Benefits
– **Faster Results**: Automates coordination and cuts transportation time for physical bundles.
– **Higher Accuracy**: Minimizes human errors in addition and data entry.
– **Teacher Convenience**: Allows evaluation from home or school, broadening examiner participation without disrupting classes.
CBSE will support rollout with OASIS login access, training videos, trial runs, and a helpline for teachers.
## Implications for Students
Students benefit from quicker result announcements, potentially by early March 2026, aiding college admissions. The system ensures fairer marking through strict adherence to schemes via digital interfaces. No changes to exam format; focus remains on answer quality.
