A Major Change Is Coming to CBSE Board Exams

If you are a CBSE teacher, principal, coordinator, or examination in-charge, the 2026 board examination session is not a routine one. CBSE has officially introduced a digital evaluation system called On-Screen Marking (OSM) that will change how answer sheets are checked, how results are prepared, and how fairness in marking is ensured.

On 13 February 2026, CBSE Headquarters conducted a nationwide webinar (around 2–3 hours long) to brief all stakeholders — schools, centre superintendents, and teachers — about the new examination procedures for Classes 10 and 12.

The message from the Board was very clear:

CBSE is not merely modernizing exams; it is modernizing the entire assessment system.

With more than 31,000 affiliated schools and lakhs of students, this reform is one of the biggest operational changes in the history of CBSE examinations.

Who Addressed the Webinar

The session was led by senior CBSE officials:

• Chairperson Shri Rahul Singh — explained the vision, scale, and transformation
• Controller of Examinations Dr. Sanyam Bhardwaj — demonstrated the digital marking portal and workflow
• Other officials including Shri Manish Agarwal — linked the reform with NEP-2020

The webinar included live portal demonstrations, marking simulations, and detailed clarifications of doubts raised by schools.

Two Board Exam Opportunities in 2026

CBSE confirmed that Class 10 students will get two chances to appear in board examinations during the same academic session.

Key points:

• Students may appear in the second exam to improve performance
• The better score will be reflected in the final marksheet
• Both scores will remain visible for transparency
• For Class 10, the List of Candidates (LOC) will reopen after the first exam attempt so improvement can be facilitated smoothly.

This policy aims to reduce exam fear and make assessment more learning-oriented instead of one-day performance based.

Changes in Class 10 (Physical Evaluation Continues)

Class 10 will still follow manual checking in 2026, but CBSE has introduced structural improvements:

• Science and Social Science answer books are divided into subject-wise sections
• Only the relevant subject teacher will evaluate that portion
• Maps and diagrams will be placed at the end of answer books
• These changes also prepare the system for future digital evaluation.

The Biggest Reform: On-Screen Marking (OSM) for Class 12

This is the centrepiece of CBSE Board Exams 2026.

Approximately:

• 18.59 lakh Class 12 students
• Nearly 1 crore answer books
• About 120 subjects
• Instead of physically transporting answer sheets to evaluation centres, CBSE will adopt digital checking.

What Actually Happens

• Students write exams on paper as usual
• Answer books go to scanning centres
• Every page is scanned
• Uploaded to secure CBSE servers
• Evaluators receive randomized digital copies for marking
• Marks are awarded online
• Teachers will not receive physical bundles of copies anymore.

CBSE expects:

• Scanning completion: about 8 days
• Evaluation: about 8–9 days (earlier about 12 days)
• Because totaling and unchecked-question errors disappear, post-result mark verification for Class 12 will largely not be required.

How the OSM Portal Works

Teachers will evaluate through the official OSS/OSM digital platform.

Login System

• User ID and password
• OTP authentication
• Profile update mandatory
• CBSE will provide practice credentials and demo answer books. Teachers are strongly advised to practice before real evaluation.

Roles in Digital Evaluation

• Evaluator / Assistant Examiner (AE): Performs question-wise marking
• Head Examiner (H): Supervises and resolves mismatches
• Validation/CNS Team: Monitors marking patterns and accuracy

Marking Features

The digital interface includes:

• Right-click marking (0.5, 1, 1.5, 2 etc.)
• Tick, cross, blank, and NA icons
• Automatic totaling
• Mandatory marking of unattempted questions
• Automatic selection of best answers in over-attempts
• The system will not allow submission if any question remains unchecked.

It also tracks:

• Time spent per question
• Marking behaviour
• Deviations from normal marking
• This makes evaluation standardized across the country.

Technical Requirements

CBSE clarified several important points:

• Laptops allowed
• No webcam required
• Auto-save + manual save available
• Power or internet interruption manageable
• Static IP Required
• Head examiners will handle wrong sets, blank pages, and re-scans.

Examination Conduct & Security Rules

CBSE emphasized strict discipline at exam centres:

• CCTV monitoring with 3-month recording retention
• Gender-appropriate frisking
• No mobile phones or electronic devices
• No seat change or subject swap
• Immediate reporting of irregularities
• CBSE announced zero tolerance for unfair means (UFM) and advised schools to brief students and parents properly.

Responsibilities of Principals and Schools

The principal, acting as Centre Superintendent, holds primary responsibility.

Schools must:

• Maintain discipline and confidentiality
• Submit answer books on time
• Follow Standard Operating Procedures (SOPs)
• Ensure staff briefing and student awareness
• Duty conflicts must be avoided (e.g., one person cannot be both evaluator and centre superintendent).

Urgent Deadlines Schools Must Note

CBSE highlighted immediate actions:

• Internal assessment upload: 14–15 February 2026
• Query submission deadline: 14 February, 5 PM
• Evaluation expected to start: around 26 February 2026
• Initial payment release: 17 February
• CBSE reported that nearly 30% of schools had not uploaded internal assessments, which may affect results.

Benefits of the New System

For Students

• Fair marking
• Faster results
• No unchecked answers
• Reduced exam pressure

For Teachers

• No travel to distant centres
• Screen-based comfortable checking
• Lower workload initially
• Higher remuneration

For Schools and CBSE

• Minimal logistical risk

Practical Concerns Addressed by CBSE

The Board also discussed real issues:

• Eye strain → breaks permitted
• Power cuts → manual save recommended
• Learning curve → practice sessions available
• Workload → limited initial copies
• Teachers should practice evaluating 3–4 sample answer books before actual duty.

What This Reform Really Means

Earlier, evaluation depended on individual examiner style.Now evaluation becomes data-tracked, monitored, and standardized.

Each marking action is recorded and analyzed.

This marks a shift:

From checking answer sheets → to measuring learning outcomes.

Key Takeaways

• Class 10 continues manual evaluation with structural improvements
• OSM will reduce errors and speed up results
• Schools must prepare immediately

Frequently Asked Questions (FAQs)

Final Advice for Schools and Teachers

Teachers should immediately update their OSS profile and practice the demo marking system.Schools must upload internal assessment marks without delay and properly brief students about examination rules and ethics.

CBSE has taken a major step toward a transparent, technology-driven examination ecosystem.The success of this reform will depend on how quickly schools and teachers adapt to it.

For educators, this is adaptation time.

For students, this is fairness time.

For the education system, this is the beginning of a more reliable assessment future.
