Teachers who participated in the Central Board of Secondary Education's (CBSE) dry run of the Online Scoring Mechanism (OSM) criticized the exercise for focusing primarily on server capacity testing, while failing to address significant operational challenges that emerged during the actual implementation of the system. They reported issues such as poor quality of scanned answer sheets, which differed from the clearer samples used in the dry run, leading to complications in evaluations. Furthermore, teachers noted a lack of independent monitoring during the dry run, raising concerns about the effectiveness of the training provided. Despite recommendations for a phased rollout, CBSE opted for a nationwide implementation for the 2026 board examinations, resulting in technical issues and complaints from both students and teachers. In response, CBSE maintained that the dry run was designed to identify modifications needed for the system, asserting that it provided a framework for improvements, including enhancements to scanning technology and user interface features.
