The Central Board of Secondary Education (CBSE) has pushed the Class 12 verification and re-evaluation application deadline to June 7, 2026, midnight. The extension follows critical portal access errors caused by large-scale DDoS cyberattacks. Concurrently, the government has launched a formal probe into the board's digital marking infrastructure.
The Central Board of Secondary Education (CBSE) has extended the deadline for Class 12 students to apply for mark verification and answer sheet re-evaluation. Initially scheduled to close at midnight on June 6, 2026, the application window will now remain accessible until midnight on Sunday, June 7, 2026. This urgent policy shift follows a barrage of technical complaints from candidates trying to access their scanned answer booklets on the board's digital portal.
The extension offers sudden relief to thousands of students nationwide who are competing for highly sought-after university admissions, where fractional shifts in board percentages can heavily dictate cut-off eligibility.
Technical Disruption and Portal Vulnerabilities
The decision to push back the deadline marks a turbulent week for the board's newly streamlined Post-Result Services Portal, which officially went live on June 2, 2026. Almost immediately after the system opened, users reported severe performance issues, including missing pages from their uploaded scripts, blurred scans, and incorrect question paper sets linked to their profiles.
The board revealed that the platform faced an unprecedented volume of coordinated cyber incidents. According to an official press release issued by the CBSE, the site was subjected to multiple high-volume request bursts resembling Distributed Denial-of-Service (DDoS) traffic patterns. Within two minutes of going live, the platform logged 1.5 million simultaneous access requests and blocked more than 100,000 unauthorized login attempts. A subsequent attack on June 3 involved a malicious Denial-of-Service (DoS) transmission of nearly 3.8 million packets during peak operational hours.
To resolve the issue and protect student records, the CBSE filed a formal complaint with the Intelligence Fusion and Strategic Operations (IFSO) unit of the Delhi Police. An FIR has been registered under Sections 66 and 43(f) of the Information Technology Act to identify the origins of the malicious traffic.
Escalating Concerns Over Digital Evaluation System
Beyond portal performance, the current post-result cycle has intensified systemic scrutiny of the board's evaluation methodologies. A significant number of Class 12 candidates raised public concerns on social media, alleging that the scanned handwriting in the provided answer booklets did not match their own.
This friction points directly toward the On-Screen Marking (OSM) digital evaluation system utilized by the board. Amid growing demands for structural transparency, the Central Government intervened earlier this week. The Cabinet Secretariat mandated the formation of a specialized one-member committee to thoroughly investigate the procurement and deployment of services related to the CBSE's OSM architecture. Concurrently, the Ministry of Education replaced outgoing chief Rahul Singh, appointing senior administrator Prashant Lokhande as the new CBSE Chairman to steer the body through the post-examination phase.
Official Sources Section
Data provided by the Ministry of Education and official CBSE statements confirm that student engagement with the post-result review channels is exceptionally high. As of June 4, the board's grievance redressal portal had successfully finalized 70,433 requests. This cumulative figure includes:
7,314 applications submitted strictly for the baseline verification of marks.
63,119 applications filed specifically for the detailed re-evaluation of individual answers or questions.
The financial framework for these steps remains locked: candidates must submit an online processing fee of ₹100 per answer book for general issue verification and ₹25 per specific question selected for re-evaluation.
Quote Section
In an official statement distributed through its verified communication channels, the board explained the rationale behind the timeline expansion:
"In the interest of students, CBSE has decided to extend the last date for submission of applications for Verification and Re-evaluation of Question(s) for the Class XII Board Examinations, thereby providing students additional time and support to complete the process. Students are requested to take note of the revised schedule and submit their applications accordingly."
Why It Matters
For high school graduates in India, the final Class 12 transcript serves as a high-stakes metric for higher education placement and professional career pathways. Because prominent institutions align their cut-off criteria tightly with raw board percentiles, a discrepancy of even a single mark can disqualify an applicant. The 24-hour extension guarantees that students affected by internal portal backlogs or server time-outs can complete mandatory Aadhaar-based authentication and process their rechecking fees without risking unfair elimination from the review process.
