The Central Board of Secondary Education’s (CBSE) re-evaluation portal on Tuesday faced a “barrage of cyberattacks” as thousands of students submitted their applications amid the controversy over the On-Screen Marking (OSM) process used to evaluate Class 12 students.

In its latest update on X, the CBSE informed that the portal is currently supporting over 8,000 concurrent users. More than 16,000 students successfully completed their submissions for re-evaluation as of 3 pm today.

“While thousands of students accessed the CBSE re-evaluation portal today, malicious actors attempted to disrupt services through a barrage of cyberattacks. Most recent being a denial of service attack attempt causing 1.5 million hits on the portal within a matter of 2 minutes and more than 1 lakh attempts of unauthorised file access,” it said.

The board assured that the platform has been refined further after student feedback, including extending session time limits to make the process more convenient and seamless.

CBSE Re-Evaluation Portal Goes Live

The CBSE opened the Verification of Marks and Re-evaluation Portal on Tuesday, allowing students who received scanned copies of their answer sheets to apply online for verification and re-evaluation of their marks. The board has clarified that this application process will remain open until June 6, 2026.

The window has been opened amid an escalating controversy over the board’s newly introduced On-Screen Marking (OSM) system. Amid mounting backlash over the OSM controversy, CBSE revised the fee structure for post-result services.

However, just a few hours after the portal went live, several students reported technical glitches. One student said they were unable to log in even after entering all details correctly.

“Please increase the login time limit to at least two hours. It takes a lot of time to carefully enter reasons and identify questions. I spent two hours entering details for four questions, but when I proceeded to payment, I was redirected to the login page,” another user wrote.
