After the portal to facilitate submission of re-evaluation requests for answer sheets to the Central Board of Secondary Education (CBSE) opened, up to 16,000 students had applied to have their papers reassessed till Tuesday (June 2, 2026) afternoon, the Board said. 

The CBSE opened the portal on Tuesday (June 2, 2026) to enable applications for verification of issues observed in the scanned copies of answer sheets it had provided, and re-evaluation of answers. The portal would remain open till the midnight of June 6, the Board said. 

The CBSE opened up its portal after the delay of a day; the portal was to be launched on June 1. 

Despite glitches in its portal, the CBSE has said “no offline applications will be accepted”. Also, requests submitted after the scheduled date and time would not be accepted, the Board has said. 

On the first day of its launch, several Class 12 students shared screenshots reporting a range of technical errors and evaluation discrepancies.

After filling out their log-in credentials (roll number, date of birth) and the captcha code, students were met with ‘Verification failed, please check details’.

Heavy server traffic caused the website to become unresponsive mid-process. Many students reported that after selecting their subjects or punching in details, the page froze entirely or redirected to a completely blank screen, forcing them to start over.

The new user interface was reportedly broken on mobile devices, including overlapping text and unclickable buttons, which was distressing for students trying to complete the process on their phones.

“The CBSE revaluation portal is currently supporting over 8,000 concurrent users. As of 3:00 p.m. today, more than 16,000 students have successfully completed their submissions,” CBSE said on Tuesday (June 2). 

“While thousands of students accessed the CBSE re-evaluation portal [on Tuesday], 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,” the CBSE further said in its official statement. 

“Based on student feedback, we have further refined the platform, including extending session time limits to make the process more convenient and seamless,” the Board said. 

“Students may apply online for resolution of issues observed in the supplied scanned copy of answer book, including missing pages, missing supplementary sheets, missing maps/graphs, blurred pages, incorrect answer book, or evaluation against a different set,” CBSE has said in its official statement.  

“Multiple issues and subjects may be selected in a single application. If students are not satisfied with evaluation they can apply for this facility,” the statement further said. 

Students may also apply online for re-evaluation of one or more questions across one or more subjects by providing the required details, including question number, and page number. They are required to ensure all intended requests, across subjects, are included before the final submission. 

Students have been instructed to enter their Aadhaar number for logging into the portal. “Aadhaar verification has been included for security reasons. For children who do not have Aadhaar, the parent’s, relative’s or guardian’s Aadhaar details may be used. In this case, the name in Aadhaar, date of birth, and gender must be of the person whose Aadhaar number is used,” CBSE officials have said. 

Legal experts have pointed out that the Supreme Court has held mandatory Aadhaar authentication to be unconstitutional. “Firstly, Aadhaar cannot be made mandatory. Adding a layer of Aadhaar verification adds some friction to the IT portal, but any impersonator who wants to enter the portal via social engineering can get in by defrauding someone to obtain their Aadhaar details and spoof the system,” a cyber security researcher and privacy advocate told The Hindu, requesting anonymity. 

The CBSE is charging ₹100 per answer book for the verification of issues observed in the scanned copies supplied, and ₹25 per question for re-evaluation.  

Once the ‘Freeze’ and ‘Proceed to payment’ button is clicked, the details are locked and cannot be edited, the Board said. Thus, students have been advised to ensure all details are correct. “The application shall be treated as successfully submitted only after successful payment through the online payment gateway,” the Board said. 

Students can download and track the status of their application through the portal.
