On-Screen Marking (OSM) System

Context

Following the release of the Class 12 board examination results in May 2026, the Central Board of Secondary Education (CBSE) faced intense public backlash, student protests, and intense scrutiny over massive evaluation discrepancies tied to its newly implemented On-Screen Marking (OSM) system.

About the News

Background:

On-Screen Marking (OSM) is a digital evaluation framework designed to transition handwritten examination papers away from physical logistics. Instead of answer scripts being packed, shipped, and graded manually with red pens, the booklets are collected at centers, scanned, digitally anonymized, and uploaded onto a secure cloud platform where evaluators grade them on computer screens.

Implementation Rush:

The CBSE first piloted an early version of OSM in 2013–14, which failed due to a lack of digital literacy and poor infrastructure. Despite its own governing body explicitly advising in June 2025 to limit OSM to low-volume, minor subjects as a controlled trial run, the CBSE bypassed the pilot phase and enforced full-scale nationwide adoption across all major subjects for over 18 lakh students in 2026.

Stated Objectives:

• Complete elimination of manual totaling and tabulation errors.
• Compressed processing timelines, reducing the evaluation cycle from 12 days to 9 days.
• Enhanced transparency to limit the need for post-result verification applications.

How It Works & Key Features

• Anonymization & Masking

To prevent examiner bias, student roll numbers and barcode identifiers are digitally masked or redacted before the scanned answer sheets are routed to evaluators.

• Digital Canvas Grading

Evaluators log into a monitored portal under video surveillance. They use digital annotation tools to overlay ticks, crosses, and assign step-wise marks directly on the scanned image canvas.

• Auto-Tabulation

The platform's software automatically aggregates question-wise scores into a final tally, completely eliminating manual addition or arithmetic errors.

• SLA-Driven Framework

The technical infrastructure and the OnMark portal were outsourced to Hyderabad-based Coempt Eduteck Pvt. Ltd. The contract features a strict Service Level Agreement (SLA) penalizing software downtime or page-loading lags at a rate of ₹1 lakh per 15 minutes.

Nature of the Discrepancies & Controversies

The full-scale rollout resulted in a severe public credibility crisis. When students applied for scanned copies of their evaluated papers, thousands of critical technical and human errors were exposed:

• Illegible Scans & Missing Pages: Over 68,000 answer booklets required emergency rescanning due to blurred images where light pencil work, mathematics steps, and diagrams failed to reproduce clearly on screen.
• Identity Mix-ups: Multiple high-profile cases emerged where students received photocopies of answer sheets that belonged to entirely different candidates, exposing critical errors during the digital masking and indexing stage.
• Severe Cybersecurity Vulnerabilities: Student whistleblowers and ethical hackers discovered massive security flaws in the OnMark frontend code, alleging the existence of static master passwords that allowed users to bypass One-Time Passwords (OTPs) and directly view or alter marking dashboards.
• Allegations of Tender Rigging: Public independent investigations by students revealed that the CBSE allegedly lowered its technical tender parameters over three successive bidding rounds, reducing mandatory capability requirements from CMMI Level 5 down to Level 3 and removing clauses regarding the vendor's past performance to favor Coempt Eduteck (historically linked to a similarly flawed 2019 exam disaster in Telangana under a previous name, Globarena) over established competitors like TCS.

System Comparison: Manual vs. Digital (OSM)

Way Forward

• Comprehensive Technical Audits

Before deploying the platform for any future examination cycles, the entire software architecture must be subjected to independent, third-party source code reviews and security audits by nodal agencies like CERT-In.

• Mandating Pilot Project Trials

The CBSE must return to the recommendations of its Governing Body, restricting digital evaluation to low-volume or purely objective testing formats before subjecting millions of high-stakes student futures to uncertified automation.

• Enhanced Evaluator Training & Redundancy

Introduce mandatory training pipelines for examiners to combat on-screen fatigue. Furthermore, the software must be integrated with mandatory dual-verification alerts if an evaluator attempts to submit a page containing unreadable or faint ink marks.

Conclusion

While the transition to On-Screen Marking represents a logically sound step toward digitizing public infrastructure, CBSE's hasty execution turned an efficiency initiative into a systemic failure. True digital transformation in high-stakes public education requires absolute procedural transparency, rigorous vendor vetting, and robust technical stability to preserve student trust and safeguard academic equity.
