CBSE Re-Evaluation Row Explained: OSM Complaints, Security Issues And More
The CBSE On-Screen Marking system has remained at the centre of controversy since the Class 12 results were declared. From student complaints over marks and alleged security vulnerabilities to answer-sheet mix-ups and tender-related questions, the issue has expanded into a major post-result debate.
CBSE Re-Evaluation Row: What Is Happening?
The CBSE re-evaluation row began after the Class 12 results, when several students started raising concerns about unexpectedly low marks and alleged issues with scanned answer copies. The discussion soon moved from individual complaints to broader questions about the On-Screen Marking system used for digital evaluation.
CBSE has said that it received 43,980 applications for Class 12 verification and re-evaluation by 12 noon on June 3, 2026. Out of these, 4,924 applications were for verification of marks, while 39,056 were for re-evaluation.
Application Numbers Shared By CBSE
According to CBSE, the re-evaluation portal has seen heavy usage since post-result services opened. The board also said its teams are monitoring the platform to keep the system secure and student-friendly.
| Application Type | Number Reported | Status Time |
|---|---|---|
| Verification of Marks | 4,924 | June 3, 2026, 12 noon |
| Re-Evaluation | 39,056 | June 3, 2026, 12 noon |
| Total Applications | 43,980 | June 3, 2026, 12 noon |
| Answer Sheets Sought Earlier | Over 11 lakh answer sheets | Applied by more than four lakh students |
How The OSM Controversy Began
This year, CBSE introduced the On-Screen Marking system, replacing the traditional manual evaluation process with a digital assessment method. Under OSM, answer scripts are scanned and evaluated digitally by examiners.
Soon after the Class 12 results were announced, many students alleged that the new system may have resulted in unexpectedly low marks. Complaints spread quickly across social media, with students questioning scanned copies, marking accuracy and the portal process.
OSM Introduced
CBSE moved from manual evaluation to digital On-Screen Marking for answer scripts.
Results Declared
Students began reporting unexpectedly low marks after Class 12 results were announced.
Complaints Spread
Concerns over scanned copies, marks and portal issues became widely discussed online.
Cyber Attack And Portal Security Concerns
CBSE said its re-evaluation portal faced a cyberattack that generated 1.2 million hits within two minutes. The board also claimed there were over one lakh attempts at unauthorised file access.
Despite the heavy traffic and attempted unauthorised access, CBSE said the portal remained functional. The board also stated that its teams were on constant watch to maintain a secure and reliable platform for students.
| Security Concern | CBSE Claim | Student Impact |
|---|---|---|
| Heavy traffic attack | 1.2 million hits were generated within two minutes | Raised concerns over portal stability and access |
| Unauthorised file access attempts | Over one lakh such attempts were reported | Raised questions about data and answer-sheet security |
| Portal function | CBSE said the portal remained functional | Students continued submitting applications online |
| Technical monitoring | CBSE said teams are on constant watch | Security and reliability remain key concerns for students |
Answer-Sheet Access And Re-Evaluation Process
More than four lakh students had earlier applied to obtain over 11 lakh answer sheets. This step is important because students generally need to view the scanned copy of their answer book before deciding whether to apply for verification or re-evaluation.
The large number of applications shows that many students are actively checking their evaluated answer scripts. For some, the concern is marks calculation; for others, it is the way responses were evaluated digitally.
- Students apply to obtain scanned copies of answer books.
- They review the scanned answer sheet and marks awarded.
- If they notice an issue, they apply for verification or re-evaluation.
- CBSE processes the request through the official online portal.
- Students should track official updates for final outcome and correction, if any.
Major Issues Raised In The CBSE OSM Row
The controversy is not limited to one complaint. It includes student dissatisfaction with marks, alleged answer-sheet mix-ups, cybersecurity concerns, portal access problems and questions linked to the OSM tender process.
| Issue | What Students / Observers Raised | Why It Matters |
|---|---|---|
| Low marks complaints | Students claimed they received unexpectedly low marks after OSM evaluation | Board marks affect college admissions and academic records |
| Scanned copy concerns | Students questioned scanned answer sheets and evaluation visibility | Transparency is important for trust in re-evaluation |
| Security vulnerabilities | Cyberattack and unauthorised file access attempts were reported | Raises concern over student data and portal reliability |
| Answer-sheet mix-ups | Some complaints referred to possible mismatch or access problems | Students need accurate access to their own answer scripts |
| Tender-related questions | Questions were raised around the OSM tender and implementation process | Public trust depends on transparent system rollout |
CBSE’s Position So Far
CBSE has stated that the portal remained functional despite the cyberattack. The board has also said that its teams are continuously monitoring the platform to ensure a secure, reliable and student-friendly experience.
At the same time, the high number of re-evaluation applications shows that many students want a closer review of their answer scripts. The coming days will be important as students track the outcome of verification and re-evaluation requests.
