CBSE OSM Evaluation Process: What the Board Says About On-Screen Marking for Class 12 Results 2026

Confusion and frustration over Class 12 board marks have been mounting among students and parents ever since CBSE announced its 2026 results, with many taking to social media to question whether the newly reintroduced On-Screen Marking system was assessing their handwritten answers, diagrams, and lengthy responses accurately. In response, the Central Board of Secondary Education has stepped forward with a detailed explanation of how the OSM process works and why it believes the system is fairer, faster, and more transparent than traditional evaluation methods.

What Is the CBSE OSM System?

On-Screen Marking is a digital evaluation system where scanned copies of students' answer sheets are assessed by examiners on computers instead of physical answer books. Answer sheets are scanned securely and uploaded to a digital platform, where evaluators assess responses online using the prescribed marking scheme. CBSE says the system eliminates totalling and tabulation errors, improves consistency in marking, speeds up result processing, and enhances security and transparency throughout the evaluation process. The board also noted that institutions such as Anna University and Rajiv Gandhi Medical University, along with several state education boards, have experimented with or adopted similar digital evaluation systems. CBSE Digital Evaluation Issues 2026: How To Apply for Rechecking and Re-Verification.

Why Are Students Raising Concerns?

The concerns emerged after students noticed unexpected variations in marks and began questioning whether the digital system could properly evaluate handwritten content, diagrams, and complex responses. Some also expressed fears that poor scanning quality or technical glitches could affect their scores. CBSE has clarified that if scanned answer sheets are unclear or unreadable, evaluators can reject them and request rescanning before assessment begins. The board further stated that evaluators undergo proper training and that answer books are reviewed by Assistant Head Examiners and Head Examiners after evaluation to maintain quality standards. CBSE Makes 3 Languages Compulsory for Class 9 From July 2026: Full List of Languages Students Can Choose From.

How Does the OSM Process Work?

CBSE follows a carefully monitored step-by-step process. Answer books first go through a secrecy process carried out by external experts to hide student identities. They are then scanned using specialised infrastructure, with the updated system keeping answer books intact during scanning to reduce the risk of mismatches. A dedicated quality-check team reviews all scanned copies and flags any that need rescanning. Scanned sheets are then distributed digitally to different regions, generally ensuring that answer sheets are not evaluated in the same region where the exam was conducted. CBSE uses whitelisted static IP addresses at evaluation centres to prevent unauthorised access. Head Examiners assign answer sheets to evaluators online, and senior examiners cross-check evaluated books for consistency.

Why Did CBSE Reintroduce OSM in 2026?

CBSE first attempted OSM in 2014 but faced technical challenges around scanning infrastructure and device availability. The 2026 rollout was made possible through significant upgrades including better scanning technology, stronger quality-control systems, improved digital infrastructure in schools, and comprehensive training programmes for teachers and evaluators.

Can Students Apply for Re-Evaluation?

Yes. CBSE has confirmed that the re-evaluation and verification process remains available under the OSM system. Students can still apply for verification of marks, photocopies of answer sheets, and re-evaluation as per existing board rules.

As digital assessment becomes increasingly common across Indian educational institutions, CBSE's upgraded OSM system will continue to be closely watched by students, parents, and educators in the months ahead.
