Teachers who participated in the Central Board of Secondary Education's (CBSE) dry run for the Online Screening Mechanism (OSM) have raised concerns about the exercise's effectiveness. They claim it focused primarily on testing server capacity rather than addressing operational challenges that later emerged during the nationwide implementation. According to the teachers, the trial did not adequately evaluate how the platform would perform under real conditions, leading to significant issues during the actual evaluation process, including poor-quality scanned answer sheets. While CBSE asserts that the dry run helped identify weaknesses and informed necessary improvements, teachers reported that no comprehensive feedback was collected post-exercise. The pilot, conducted in January with representatives from five schools, lacked independent monitoring, and many evaluators faced difficulties with unclear scanned copies. Despite recommendations to pilot the system in subjects with fewer answer books before a full rollout, CBSE proceeded with a nationwide launch for the 2026 board examinations, which subsequently faced technical issues and criticism.
