Overview
The CBSE introduced On Screen Marking (OSM) for the 2026 Class‑12 examinations. Over 18 lakh students were affected. Lack of training, missing standard operating procedures (SOP) and inadequate pilot testing led to widespread errors, mismatched scripts and delayed re‑evaluation.
Key Developments
- More than 1 crore answer sheets were scanned in record time without a pilot run.
- Students reported missing or unreadable scripts, and many supplementary answer sheets were not evaluated.
- CBSE reduced fees for script access and re‑evaluation and extended the access deadline repeatedly, finally closing on 25 May 2026.
- The Education Minister announced that the IITs would assist in resolving the problem.
- Over 1.25 lakh students applied for access to nearly 4 lakh answer scripts within hours of the window opening.
Important Facts
- The NTA showed a stark contrast: it runs the JEE smoothly, but struggled with the NEET earlier, exposing systemic weaknesses.
- No statistical validation was done to compare OSM scores with traditional marking, violating best‑practice testing protocols.
- Screen fatigue of evaluators was not assessed, raising concerns about scoring bias.
Exam Relevance
Understanding this fiasco helps aspirants answer questions on:
- Education governance and the role of autonomous bodies like NTA and CBSE.
- Policy implementation challenges, especially the need for pilot testing and SOPs before large‑scale reforms (GS2: Polity, GS3: Economy).
- Impact of digital transformation on public services and the importance of stakeholder training (GS3: Economy).
- Accountability mechanisms for ministries and the role of the Education Minister in crisis management (GS2: Polity).
Way Forward
Short‑term: Complete a transparent re‑evaluation, refund fees where justified, and publish a detailed audit of the OSM process.
Long‑term:
- Conduct a pilot on a small sample before full rollout and compare scores statistically.
- Develop and enforce robust SOPs for scanning, evaluator training, and screen‑fatigue monitoring.
- Set up an independent oversight committee comprising education experts, technologists and representatives from IITs.
- Introduce a dual‑mode evaluation (OSM + manual) for at least two years to ensure reliability.
Addressing these steps will restore confidence in the school examination system and safeguard the future of millions of students.
