The Central Board of Secondary Education (CBSE) opened its online portal for Class 12 students to request re-evaluation of answer sheets on June 2, 2026, a day behind schedule. By Tuesday afternoon, over 16,000 students had submitted applications for verification and re-evaluation, the Board announced. The portal was initially scheduled to go live on June 1 but was delayed by one day.
The CBSE portal allows students to apply for two services: verification of issues in scanned copies of their answer sheets and re-evaluation of specific questions. The portal, which remains open until midnight on June 6, 2026, mandates online-only submissions. No offline applications will be accepted, and late requests will not be processed. The Board emphasized that once details are locked and payment is made, corrections cannot be made.
From the moment the portal went live, students reported multiple technical issues. Many encountered login failures even after entering correct credentials such as roll number, date of birth, and captcha code. Heavy server traffic caused the website to become unresponsive during submission. Mobile users faced particularly severe problems, including overlapping text, unclickable buttons, and frequent blank screens. These glitches disrupted the application process, forcing students to restart their submissions multiple times.
In addition to technical difficulties, the CBSE revealed that its portal faced multiple cyber threats. According to the Board, malicious actors launched a barrage of attacks, including a denial-of-service (DoS) attempt that generated 1.5 million hits in just two minutes. There were also over 100,000 unauthorized file access attempts. The CBSE stated that it had refined the platform based on student feedback, including extending session time limits to improve usability.
Students can apply for verification of issues such as missing pages, supplementary sheets, maps, graphs, blurred pages, incorrect answer books, or evaluation against a different set. They may also request re-evaluation of one or more questions across subjects by providing the question number and page number. The Board allows multiple subjects and issues to be included in a single application. Students are required to enter their Aadhaar number for logging in, citing security reasons. In cases where students do not have Aadhaar, they may use the Aadhaar details of a parent, guardian, or relative, provided the name, date of birth, and gender match.
The CBSE charges ₹100 per answer book for verification and ₹25 per question for re-evaluation. Students must click the ‘Freeze’ and ‘Proceed to payment’ buttons to finalize their request; once done, details cannot be edited. Successful submission is confirmed only after completing the online payment. Applicants can track the status of their requests through the portal.
Legal experts have raised concerns regarding the mandatory Aadhaar authentication requirement. They point out that the Supreme Court has previously ruled that mandatory Aadhaar authentication is unconstitutional. A cybersecurity researcher and privacy advocate, speaking on condition of anonymity, argued that Aadhaar verification adds unnecessary friction and does not prevent impersonation if someone is determined to bypass the system.
