Digital evaluation system for board examination answer scripts — controversial due to implementation flaws and transparency concerns.

Why in News

The Central Board of Secondary Education (CBSE) faced severe criticism in June 2026 following technical glitches in its On-Screen Marking (OSM) system, including blurred script scans and inconsistent marking patterns that affected Class XII board examinations.

Key Facts

  • OSM is a digital evaluation platform where scanned answer scripts are assessed electronically by examiners on computer screens instead of physical paper checking.
  • The system was rolled out without adequate pilot testing during the 2025-26 academic session, causing widespread evaluation errors.
  • Technical failures included server crashes, poor-quality scanning equipment producing illegible digital files, and incomplete answer script uploads.
  • Students were charged fees to access their own digitised answer scripts, creating financial barriers to accountability.
  • The controversy raised questions about Standard Operating Procedures (SOPs) and the absence of real-time independent moderation in digital evaluation. (UPSC Mains Usage: Links to GS4 Ethics — Transparency in Public Administration, Accountability mechanisms)
  • Distributive justice concerns emerged as marking errors directly impacted competitive university admissions and scholarship allocations.
  • The incident highlighted the need for AI-driven audit controls and anomaly-detection systems in large-scale public evaluations. (UPSC Mains Usage: Technology in Governance — GS2)
