Recent Technical Challenges in CBSE's Digital Evaluation System
The Central Board of Secondary Education, commonly known as CBSE, introduced its On-Screen Marking or OSM system for evaluating Class 12 answer sheets in the 2026 board examinations. This digital approach was intended to streamline the process by scanning physical answer books and allowing evaluators to mark them on computer screens. However, shortly after the declaration of results, the associated re-evaluation portal encountered significant technical difficulties that affected thousands of students seeking to review their scanned copies or apply for mark revisions.
Students across India reported difficulties accessing the portal, including repeated crashes during peak usage times. The portal, which opened for re-evaluation applications around mid-May 2026, struggled under the volume of traffic from students disappointed with their scores. Many described screens freezing, payment gateways failing during fee submissions for accessing answer sheets, and incomplete loading of scanned documents.
Background on the Introduction of On-Screen Marking
CBSE decided to implement OSM for Class 12 evaluations starting with the 2026 exams to enhance accuracy and reduce manual handling errors associated with traditional paper-based checking. Under this system, answer sheets are scanned into digital format, and trained evaluators access them through a secure online platform to assign marks according to standardized schemes. The board had previously conducted mock runs and issued instructions to schools to prepare teachers for the transition, emphasizing practice sessions on the portal.
The shift to digital evaluation aligns with broader efforts to modernize examination processes in India's school education system. Officials highlighted potential benefits such as better traceability of marks awarded for each question and reduced chances of physical answer sheet loss or damage. Despite these goals, the rollout revealed vulnerabilities in handling high concurrent user loads during the post-result phase.
Student and Parent Experiences with Reported Issues
Following the release of Class 12 results, which showed a pass percentage of 85.20 percent, a notable decline from the previous year, numerous students initiated re-evaluation requests. Complaints quickly surfaced on social media and through direct channels to the board. Common issues included blurred or unclear scanned images of answer sheets, missing pages in multi-page responses, and apparent mismatches between marks shown for individual questions and the final total.
Parents expressed frustration over the added stress during what should have been a period of relief after examinations. Some students noted that even when their written answers aligned closely with the official marking scheme, deductions appeared inconsistent or unexplained. The portal's instability meant that many could not complete applications or view their digitized sheets promptly, leading to prolonged uncertainty about academic futures.
Specific Technical Glitches Encountered
The problems extended beyond user access to core system functionalities. Evaluators involved in the initial marking phase had also faced challenges such as slow system performance and login difficulties, though the primary public complaints centered on the student-facing re-evaluation module. Reports mentioned payment failures when attempting to pay the required fee for scanned copies, unresponsive interfaces during high-traffic periods, and occasional display of incorrect or incomplete data.
One notable aspect involved the handling of long answer responses spanning multiple pages, where step-wise marking sometimes failed to register properly in the digital interface. These issues prompted widespread discussions about the readiness of the infrastructure to support the new system at scale.
Government Response and Ministry Intervention
Union Education Minister Dharmendra Pradhan directed the CBSE to provide a comprehensive report on the glitches. In response to the mounting concerns, the Ministry of Education announced the involvement of technical specialists from premier institutions to assist in diagnosing and rectifying the problems. This step was taken to ensure swift restoration of reliable services for affected students.
The minister expressed confidence that the collaborative effort would lead to a resolution, emphasizing the importance of maintaining trust in the examination and evaluation processes that impact millions of young learners annually.

Deployment of Experts from IIT Madras and IIT Kanpur
Technical teams from the Indian Institute of Technology Madras and the Indian Institute of Technology Kanpur were specifically tasked with examining the portal's performance. IIT Madras Director V. Kamakoti confirmed that a faculty member and a project staff specialist had been dispatched to CBSE headquarters in Delhi. Their mandate included conducting a thorough review of server logs, performing data analytics, and carrying out an overall health assessment of the digital infrastructure.
The experts focused on key areas such as portal stability under load, server response times, login authentication mechanisms, and the functionality of the payment gateway. Recommendations for immediate and long-term improvements to workflows and system architecture were also part of their scope.

The board maintained that its On-Screen Marking portal did not suffer from any security breaches or vulnerabilities that could compromise data integrity. Officials clarified that while technical glitches occurred due to high demand, the system remained secure. Any prior reports of potential weaknesses had been addressed through standard channels, and ongoing audits were reinforcing protections.
CBSE also noted that students who had successfully applied would receive their scanned copies, and processes for mark verification would continue once stability was restored. The emphasis remained on transparency and addressing legitimate concerns without undermining the overall evaluation framework.
Impact on Students Seeking Re-Evaluation
The disruptions left many Class 12 students in limbo, particularly those whose results fell short of expectations for college admissions or competitive exams. The re-evaluation window is critical for correcting any genuine discrepancies, and delays in portal access compounded anxiety during an already high-pressure time.
Schools and parents advocated for extended deadlines or alternative mechanisms to ensure fair opportunities. The situation underscored the challenges of transitioning large-scale public systems to digital platforms without adequate stress testing for peak periods.

This episode highlights the complexities involved in digitizing evaluation processes for national-level examinations serving millions. Factors such as varying internet connectivity across regions, the need for robust cloud infrastructure, and user-friendly interfaces for both evaluators and applicants play crucial roles in success.
Stakeholders, including educators and technology specialists, have called for phased implementations, extensive simulations, and real-time monitoring tools in future iterations. The experience serves as a case study in balancing innovation with reliability in public service delivery.
Ongoing Resolution Efforts and Expected Outcomes
With the IIT teams actively engaged, work is underway to identify root causes and deploy fixes. This includes optimizing server capacity, refining code for better error handling, and enhancing user support features. The ministry and CBSE are prioritizing the completion of pending re-evaluation requests to minimize disruption to students' academic timelines.
Updates from official channels indicate a commitment to full system restoration and preventive measures against recurrence. Students and parents are advised to monitor the CBSE website for announcements on restored services and any revised procedures.

Future Outlook for Improved Evaluation Processes
Looking ahead, the integration of advanced technical expertise is expected to strengthen the foundation of digital evaluation in school examinations. Lessons from this rollout will likely inform enhancements in scalability, security protocols, and accessibility features.
Continued dialogue between educational authorities, technology partners, and the student community can foster more resilient systems that uphold the integrity of assessments while adapting to modern needs. The focus remains on supporting learners through reliable and transparent mechanisms.
