New Delhi, May 30 -- An internal observation report from a dry run of the Central Board of Secondary Education's on-screen marking system, conducted at five Delhi schools in January 2026, flagged at least 36 technical, operational and evaluation-related concerns - including risks of "blind or superficial checking", weakened supervisory oversight, absence of safeguards against data loss and a finding that the system offered no opportunity for evaluators to deliberate or arrive at a consensus on marks - weeks before the board deployed it at national scale for Class 12 board examinations.
