Understanding CBSE's On-Screen Marking System for Class 12 Exams

The CBSE Class 12 Board examination marks a pivotal moment in a student’s academic journey, transforming the routine of school into a significant milestone. The scores achieved in this high-stakes examination do not merely conclude an educational chapter; they play a crucial role in determining future opportunities such as college admissions, course selections, scholarships, and eligibility criteria. Given the weight of these outcomes, the evaluation process for Class 12 is critically important. Even minor errors in marking can significantly affect rankings, limit options, or undermine a student’s confidence. To address these challenges, the Central Board of Secondary Education (CBSE) has announced the implementation of On-Screen Marking (OSM) for Class 12 answer sheets starting from the 2026 examinations, while Class 10 evaluations will continue using traditional methods for the time being.
