The CBSE 12th Revaluation Window online application window for Verification of Marks and Re-evaluation closed on June 7, 2026. The Central Board of Secondary Education originally set the deadline for June 6, but extended it by one day to midnight of June 7 due to initial portal access glitches and a coordinated cyber attack.
The CBSE Class 12 Re-evaluation and Verification portal is now live. After initially being postponed from May 29 to June 1, 2026, to resolve technical glitches and stabilize the system, the facility is fully operational. Applications must be submitted by June 6, 2026.
Students dissatisfied with their marks will be allowed to apply for verification of marks, obtain scanned copies of answer sheets, and request re-evaluation of specific questions through the official CBSE portal. On May 28, 2026, the Education Minister publicly acknowledged discrepancies in the ongoing re-evaluation cycle and promised that every single student grievance would be actively resolved.
The CBSE Class 12 Revaluation 2026 process has become one of the biggest educational discussions in India following the controversy surrounding the recently announced board examination results. After the declaration of results on May 13, students across the country started searching for CBSE Revaluation 2026, CBSE Verification Process, CBSE OSM Controversy, CBSE Answer Sheet Mismatch, CBSE Rechecking Date, CBSE Result Error, CBSE Photocopy of Answer Sheet, CBSE Re-evaluation Form, CBSE Class 12 Verification, and CBSE Supplementary Exam 2026.
This year’s controversy mainly revolves around the newly implemented On-Screen Marking (OSM) system. Several students alleged that uploaded answer sheets during verification did not belong to them, while others reported unexpectedly low marks despite scoring exceptionally well in competitive examinations such as JEE Main. The issue quickly gained attention on social media, leading to nationwide discussions regarding transparency in the evaluation process.

What is the CBSE OSM Controversy?
The biggest reason behind the ongoing CBSE result controversy is the implementation of the On-Screen Marking (OSM) evaluation system. Under this process, students’ physical answer sheets were digitally scanned and evaluated online by examiners through a centralized system.
Although CBSE introduced the digital evaluation system to improve transparency and speed, several students raised concerns after the declaration of results.
The major complaints reported by students include:
- Extremely low marks compared to expectations
- Alleged mismatch of uploaded answer sheets
- Incorrect scanned copies during verification
- Physics and Mathematics evaluation discrepancies
- Portal crashes during verification requests
- Blurred or unreadable answer sheet copies
- Large difference between JEE Main percentile and CBSE board marks
The controversy became more serious after several students claimed that the answer sheets uploaded under their roll numbers appeared to belong to different candidates entirely.
Why Students Are Questioning the Evaluation System
Many students who scored above the 95 percentile in competitive examinations reportedly secured unexpectedly low marks in CBSE board subjects. This created confusion among students and parents regarding the consistency of the evaluation process.
Several students claimed:
- Step marking was not awarded properly
- Answers were left unchecked
- Internal choices were ignored
- Marks were not totaled correctly
- Scanned answer sheets were mismatched
Parents and coaching institutes also raised concerns over the drastic drop in scores compared to previous years.
The CBSE Class 12 Result 2026 controversy primarily stems from the mass rollout of the On-Screen Marking (OSM) digital evaluation system. This reform sparked widespread backlash from students, parents, and educators due to sharp declines in scores, technical glitches, and alleged paper mismatches.
Key Issues in the Controversy
- The On-Screen Marking (OSM) Backlash: For the 2026 exams, CBSE transitioned to digitally scanning answer sheets and having teachers grade them on computers. Following a 3.19% drop in the national pass rate, critics alleged the software was glitchy and led to overly strict, inaccurate, or uneven step-marking.
- “Not My Answer Sheet” Mismatch Allegations: The controversy intensified during the post-result verification process. Multiple students going through the CBSE Exam Results platform publicly alleged that the scanned Physics answer sheets uploaded under their roll numbers were in completely different handwriting and belonged to other candidates.
- Competitive Exam Discrepancies: Parents flagged extreme anomalies where students scored in the 97th percentile in highly competitive exams like JEE Main but were marked as failed or scored near-failing marks in their core CBSE science subjects.
- Technical and Administrative Failures: As millions of students rushed to request verification copies, the online re-evaluation portal suffered severe crashes, payment processing errors via partner banks, and instances of highly blurred, unreadable scanned pages.
Board and Government Intervention
- CBSE Official Response: The board firmly defended the transparency and precision of the OSM system. However, regarding the viral answer-sheet swapping cases, CBSE admitted a localized mistake in specific instances, rectifying the student’s physics marks and updating the portal.
- Education Ministry’s Assurance: On May 28, 2026, the Education Minister publicly acknowledged discrepancies in the ongoing re-evaluation cycle and promised that every single student grievance would be actively resolved.
- IIT and Parliamentary Scrutiny: To restore trust in India’s largest school board, a dedicated team of experts from IIT Madras was dispatched to review CBSE’s digital infrastructure, while a Parliamentary Panel has stepped in to officially audit the entire marking scheme.
The corrected and stabilized verification and re-evaluation portal opens on June 1st, 2026. Students who notice errors in their evaluated files can officially log complaints on the CBSE Portal.

CBSE Official Response to the Controversy
CBSE has defended the transparency of the OSM system while acknowledging that isolated technical errors may have occurred in specific cases.
The board clarified that:
- Every grievance submitted through official channels will be reviewed
- Technical mismatches will be corrected
- Students can apply for verification and re-evaluation
- Updated marksheets will be issued if changes occur
The Education Ministry has also reportedly taken note of the complaints and assured students that all legitimate issues will be resolved fairly.
When Will CBSE Revaluation 2026 Begin?
According to the latest updates, the CBSE Class 12 revaluation and verification process is expected to begin from June 1st, 2026.
Students will be allowed to:
- Apply for verification of marks
- Obtain photocopies of answer sheets
- Request re-evaluation of specific questions
The complete schedule will be released on the official CBSE portal.
Stages of CBSE Revaluation Process 2026
CBSE follows a three-step revaluation process.
1. Verification of Marks
In this stage, CBSE verifies:
- Whether all answers were checked
- Whether marks were calculated correctly
- Whether marks were entered properly
- Whether any answer remained unevaluated
This is the first step for students who suspect calculation errors.
2. Obtaining Photocopy of Evaluated Answer Book
Students can request scanned copies of their evaluated answer sheets after the verification stage.
This helps candidates:
- Review examiner markings
- Check unchecked answers
- Identify totaling mistakes
- Verify step marking
The photocopy stage has become extremely important this year due to the OSM controversy.
3. Re-evaluation of Answers
Students who identify discrepancies can apply for re-evaluation of specific answers.
CBSE allows re-evaluation only for:
- Questions identified by the student
- Answers where marks appear incorrect
- Unchecked portions of the answer sheet
If marks increase or decrease after re-evaluation, the revised score becomes final.

Step 3

CBSE Revaluation Fee Structure (Reduced Fee for 2026)
Although CBSE has not officially announced the 2026 fee structure yet, the expected charges are:
| Service | Expected Fee |
|---|---|
| Verification of Marks | ₹100 per subject |
| Photocopy of Answer Sheet | ₹100 per subject |
| Re-evaluation | ₹25 per question |
The Ministry of Education intervened and drastically slashed prices due to widespread student dissatisfaction following glitches linked to the new On-Screen Marking (OSM) system. To ease financial strain on families and encourage transparency, CBSE made these post-result services significantly cheaper. Additionally, in a historic first, the re-evaluation fee of ₹25 per question is completely refundable if your marks go up.
Since the photocopy application window already closed, the next immediate milestone is the rescheduled re-evaluation portal opening on June 1, 2026.
Who Should Apply for CBSE 12th Revaluation 2026
Students may consider applying if:
- Their marks are much lower than expected
