"Digitisation of high-stakes public examinations must be preceded by robust pilot-testing and grievance redressal mechanisms." Discuss in light of the 2026 CBSE On-Screen Marking controversy.

CBSE's shift to On-Screen Marking (OSM) for Class 12 from the 2026 exams [1] — scanning answer scripts for evaluation on a digital platform [2] — was meant to raise speed and objectivity. The disputes that followed show technology in high-stakes exams must be proven and cushioned before scale.

The promise of digitisation

• Removes physical transit of scripts, enables centralised monitoring and random allocation to examiners, cutting handling errors.
• Government has held that OSM improved transparency and objectivity in evaluation [3].
• Faster turnaround matters where Class 12 marks gate admission to professional courses.

Why pilot-testing must precede rollout

• Reported defects — blurred scans, missing pages, mismatched sheets, incomplete uploads — were surfaced only after results, when reversal is costly [4].
• A court-monitored controversy followed, with the Delhi High Court issuing notice to the Centre and CBSE on a PIL questioning the system's reliability [4].
• Procurement itself became suspect: government constituted a panel to probe procurement of OSM services [5] — a design flaw traceable to inadequate prior validation.
• Contrast: staged pilots in select subjects allow failure at low cost; nationwide first-run does not.

Why grievance redressal is the second precondition

• Volume overwhelmed the window — CBSE received over 70,000 applications through post-result grievance redressal [6], and had to extend the last date for verification/re-evaluation [7].
• Portal congestion converts a procedural right into a lottery; students without digital access or legal recourse suffer most.
• Second ARC's 12th Report, "Citizen Centric Administration", stresses time-bound, accessible internal grievance machinery as the core of service delivery [8] — a benchmark unmet here.

Way forward

• Phased pilots with published audit of scan quality; independent third-party validation before scaling.
• Free, automatic re-scan on complaint; extended windows sized to expected volume; escalation ladder with defined timelines.

Digitisation of evaluation is desirable and probably irreversible; the OSM episode is an argument for sequencing, not for retreat. Reform that pairs pilot-testing with a strong citizens'-charter-style redressal system can deliver both administrative efficiency and the fairness that education as an enabler of Article 21A and SDG-4 demands.
