IIT Madras Team To Probe CBSE OSM Row
IIT Madras Director V Kamakoti has said the institute’s expert team is focusing on identifying what went wrong with CBSE’s On-Screen Marking system, rather than only fixing immediate glitches. The review follows complaints from students over marks, scanned answer sheets and the revaluation portal.
CBSE OSM System Under Review
CBSE introduced the On-Screen Marking system for the 2026 board exams, moving from physical answer-sheet evaluation to a digital checking process. Under the system, scanned answer sheets were uploaded to a secure platform for teachers to evaluate online.
However, several students later raised concerns over alleged unchecked answers, missing step marking, blurred scans, mismatched pages and errors in marks uploaded after evaluation.
IIT Madras Expert Team Probe
Kamakoti said a four-member expert team has been deployed to audit the CBSE revaluation portal and examine the root cause of the problems. The team is expected to check whether the issues were caused by software deployment gaps, infrastructure stress, server problems or possible cyber-related disruptions.
He said the focus is not “firefighting,” but understanding the technical failure points so that future digital evaluation systems can be made more reliable.
CBSE Revaluation Portal Glitches
Students also reported payment failures and access issues while applying for post-result services through the CBSE portal. The complaints prompted Union Education Minister Dharmendra Pradhan to seek a detailed report and involve experts from IIT Madras and IIT Kanpur.
CBSE has defended the digital evaluation system, saying it was meant to improve transparency and reduce human error. The IIT review is now expected to help identify safeguards, technical checks and deployment standards for future exam evaluation platforms.
