The Central Board of Secondary Education ( CBSE ) will implement On-Screen Marking ( OSM ) for all Class 12 answer scripts beginning in 2026 . This digital evaluation system aims to enhance accuracy and transparency in grading board exams. Class 10 answer scripts will continue to be evaluated using traditional pen-and-paper methods.
CBSE Introduces Digital Evaluation for Class 12
Starting in 2026, CBSE Class 12 board exams will undergo digital evaluation. Physical answer booklets will be scanned into secure digital files. Examiners will then mark these digital scripts remotely. This move follows a pilot program in 2014.
How On-Screen Marking Works
The OSM process involves several key steps. Industrial scanners convert physical answer sheets into high-resolution PDF files. Verified examiners access these scripts through a secure online portal. Digital tools allow teachers to mark directly on the screen.
Key Features of OSM
- Mandatory Question Validation: The system prevents examiners from completing a script without marking every question. This ensures no student response is missed.
- Automated Marks Calculation: Digital tools automatically sum marks for each section. This eliminates human arithmetic errors common in manual grading.
- Real-time Progress Monitoring: Chief Examiners use a live dashboard. They can monitor evaluator speed and accuracy in real-time.
Comparison of Evaluation Methods
The transition to OSM for Class 12 represents a significant shift from the traditional methods used for Class 10. This digital approach offers advantages in speed and error reduction.
| Feature | Class 10 (Secondary) | Class 12 (Sr. Secondary) |
| Marking Method | Traditional Pen-and-Paper | On-Screen Marking (OSM) |
| Data Entry | Manual Posting | Automatic Sync |
| Error Control | Manual Verification | System-Driven Validation |
| Result Speed | Standard Processing | Accelerated Digital Flow |
The implementation of OSM is designed to streamline the evaluation process. It ensures a more efficient and accurate assessment for Class 12 students.
