CBSE verification re-evaluation portal 2026
CBSE had earlier activated its portal for Verification of Issues and Re-evaluation of answer sheets, allowing students to apply online for post-result review services.
As per official guidelines, Aadhaar-based verification has been made mandatory for login due to security reasons. Students without Aadhaar can use the Aadhaar details of a parent, guardian, or relative, provided the demographic details (name, date of birth, and gender) match the Aadhaar holder.
CBSE students re-evaluation deadline 2026
The application window for verification and re-evaluation remains open from June 2, 2026, to June 6, 2026 (midnight). No offline applications or late submissions will be accepted.
CBSE re-evaluation fee structure
The fees for seeking verification of issues noticed on answer scripts are set at Rs 100 for each answer script, whereas for the re-evaluation application, it stands at Rs 25 per question. However, it should be noted that payments are accepted only through online modes, including UPI, debit card, credit card, or net banking.
CBSE answer sheet verification: What issues can be raised
The verification procedure includes such aspects as missing pages, blurred pages, wrong answer sheets, or evaluation discrepancies. Multiple issues can be raised by students across subjects in a single application.
CBSE Re-evaluation Process: Step-by-step guidelines for students
For re-evaluation, candidates must specify question numbers and relevant page details before final submission. Once the “Freeze and Proceed to Payment” option is selected, no further changes can be made.
Important instructions for CBSE applicants
The board has advised students to carefully review all details before final submission, as only one application for verification and one for re-evaluation is permitted per candidate. Applications will be considered complete only after successful payment confirmation.
Students can also track the status of their requests through the portal after submission. A visual guide and tutorial video have been made available to assist applicants in completing the process.
CBSE stated that all requests will be examined, and outcomes will be communicated after the completion of the review process. The board has urged students to adhere strictly to the deadline and official instructions.
