In an effort to modernize and improve the efficiency, transparency, and accuracy of assessment processes, the Central Board of Secondary Education (CBSE) is implementing a significant change starting from the year 2026. This transformation involves shifting from traditional manual evaluation of answer sheets to a digital, on-screen marking system for Class 12 board examinations. This comprehensive guide explains what the CBSE On-Screen Marking System (OSM) entails, how it operates, its benefits, challenges, and its impact on students, teachers, and evaluation processes.
Understanding CBSE On-Screen Marking System (OSM)
The CBSE On-Screen Marking System (OSM) is a groundbreaking digital evaluation approach where Class 12 answer sheets are scanned, stored, and evaluated online via a secure digital platform. Unlike the conventional method, where examiners physically handle stacks of answer books, OSM allows evaluators to review and mark scripts digitally, leading to faster, more accurate, and transparent result processing.
What is CBSE On-Screen Marking?
On-Screen Marking (OSM) leverages technology to digitize the evaluation process. After completing their exams, students’ handwritten answer sheets are scanned and uploaded onto a secure online platform. Examiners then review these scanned images on their computers, marking answers question by question using a digital interface. This online method replaces the traditional manual checking, reducing physical handling and increasing oversight.
Key Features of CBSE OSM
- Digital evaluation of answer scripts through high-resolution scans.
- Secure online platform with controlled access for examiners and moderators.
- Automatic computation of total scores and generation of result data.
- Comprehensive audit trails ensuring transparency and accountability.
- Real-time monitoring of evaluator activity and progress.
Implementation Timeline and Scope
According to CBSE notifications, the On-Screen Marking system will be applied starting with the Class 12 board examinations in 2026. This marks a significant shift, with the system being gradually integrated to streamline evaluation processes nationwide.
| Year | Applicable Examinations | Status |
|---|---|---|
| 2026 and onwards | Class 12 Board Exams | Transitioning to Digital Evaluation |
| 2026 and onwards | Class 10 Board Exams | Remaining with Traditional Method (for now) |
Official notifications and instructions for this transition are communicated through workshops, webcasts, and official circulars, ensuring that all stakeholders are well-informed and prepared for the change.
Step-by-Step Process of CBSE On-Screen Marking
1. Scanning of Answer Sheets
Post-examination, answer books are transported to designated evaluation centres. Each sheet, including blank pages, is scanned with high precision. These digital copies are reviewed for clarity, correct sequencing, and completeness before further processing.
2. Uploading to a Secure Digital Platform
The scanned images are uploaded to CBSE’s secure evaluation portal. Each script receives a unique digital identification code, removing the necessity for physical movement and enabling centralized management.
3. Allocation of Scripts to Examiners
The evaluation system assigns scripts randomly and securely to authorized examiners and moderators. The system also provides real-time updates on evaluation progress and workload distribution.
4. Digital Marking by Evaluators
Examiners access each script via their login, viewing the scanned answer sheet on one side and entering marks through a digital marking panel on the other. They are required to address each question, with built-in checks preventing omission.
5. Review and Moderation
Associate and head examiners can review marking decisions, compare scripts, and make necessary adjustments within the platform. Every change or review is logged, maintaining a comprehensive audit trail.
6. Automatic Calculation and Final Result Generation
The system sums marks automatically, reducing manual errors, streamlining result compilation, and ensuring accuracy.
Advantages of CBSE On-Screen Marking System
| Aspect | Advantages |
|---|---|
| Speed | Accelerates evaluation and result release cycles, enabling quicker dissemination of results. |
| Accuracy | Reduces human errors through automated total calculation and mandatory question-wise marking. |
| Transparency | Provides detailed logs, audit trails, and monitoring, increasing trust and accountability. |
| Logistics & Safety | Eliminates risks associated with physical handling, such as damage or loss of answer books. |
| Consistency | Ensures uniform marking standards across all examiners. |
| Eco-friendly | Reduces paper usage, travel, and logistics costs, making the process sustainable. |
Challenges and Concerns of the CBSE On-Screen Marking System
| Aspect | Concerns / Challenges |
|---|---|
| Initial Setup | Requires infrastructure upgrades, training, and calibration at evaluation centres. |
| Technical Dependencies | Dependence on high-quality scanning, stable internet connectivity, and power backup. |
| Data Security & Privacy | Handling of sensitive data necessitates robust cybersecurity measures. |
| Evaluator Comfort | Screen fatigue and eye strain could impact examiner performance over long hours. |
| Transition Phase | Initial implementation may encounter resistance or teething problems impacting evaluation timelines. |
| Cost Implications | Investment in infrastructure, training, and maintenance. |
Impact of On-Screen Marking on Students
What Does OSM Mean for Class 12 Students?
For students, the evaluation process becomes more precise, transparent, and faster. Since answer scripts are digitized, clarity in handwriting and presentation plays a critical role in ensuring smooth evaluation. Enhanced accuracy and quicker result announcements are the key benefits.
How Should Students Prepare Their Answers?
Students are encouraged to maintain neat handwriting, clear diagrams, and well-structured answers. Specific tips include:
- Write legibly, avoiding cramped or messy handwriting.
- Use proper margins and label diagrams clearly with bold, legible text.
- Number questions distinctly and keep answers within the designated space for clarity.
- Avoid overwriting or scratching, as scanned images need to be clear.
- Ensure answers are properly aligned to facilitate easier digital assessment.
What About Teachers and Examination Centres?
Changes for Evaluators and Moderators
Teachers and evaluators will now access answer scripts via a digital portal, mark answer sheets on their computers, and submit marks electronically. This process enhances accountability and allows real-time monitoring of evaluation progress.
Preparation and Training
CBSE conducts workshops, mock assessments, and training sessions to familiarize evaluators with the portal. Requirements for evaluation centres include:
- Reliable internet connectivity
- Computers with updated browsers and necessary software like Adobe Reader
- Power backup solutions
- Secure storage and handling protocols for answer sheets during scanning
Pros and Cons of the CBSE OSM System

Frequently Asked Questions (FAQs)
Will the marking scheme or difficulty level change?
No, the evaluation criteria and question difficulty remain unchanged. The system only affects the mode of evaluation, shifting from manual to digital.
Will this system impact the marks awarded to students?
Theoretically, no. The goal is to improve accuracy and consistency, which may actually reflect true performance more fairly. Well-structured, clear answers will benefit most.
Does On-Screen Marking ensure better fairness?
Yes, with better monitoring, logging, and standardized marking, the system aims to provide a fairer evaluation process, reducing chances of human bias or errors.
How will exams still be conducted?
Students will continue writing answers manually on answer sheets as usual. The change pertains exclusively to the evaluation process post-exam.
