The Central Board of Secondary Education (CBSE) has come under scrutiny following complaints from Class 12 students regarding the newly implemented On-Screen Marking (OSM) system, which they believe has resulted in lower-than-expected marks in subjects like Physics, Chemistry, and Mathematics. Many students and parents expressed their concerns on social media, highlighting discrepancies between expected scores and actual results, especially for those who performed well in the Joint Entrance Examination (JEE) Main. CBSE clarified that OSM is not a new evaluation method but a transition to digital assessment of scanned answer sheets. This system aims to enhance accuracy, consistency, and transparency in marking while maintaining existing evaluation criteria. The board noted that answer sheets are scanned after ensuring student anonymity and digitally assigned to evaluators across different regions. CBSE had previously experimented with OSM in 2014 but faced infrastructure challenges, leading to its discontinuation. The reintroduction in 2026 included improvements in scanning technology and quality checks. However, approximately 13,000 answer sheets were manually checked this year due to issues with the clarity of scanned copies.
