CBSE Re-Evaluation 2026: Key Highlights

Students are advised to carefully review their answer scripts and follow official CBSE guidelines while applying for verification or re-evaluation.

What Triggered the OSM Controversy?

The controversy emerged after CBSE implemented the On-Screen Marking (OSM) system for Class 12 board examinations.

Under this system, answer sheets are scanned and evaluated digitally by examiners.

However, many students alleged problems such as:

• Mismatched handwriting in uploaded answer sheets
• Swapped or missing pages
• Blurred scanned copies
• Portal crashes during access
• Payment-related glitches

Several students took to social media claiming that the answer scripts uploaded under their roll numbers did not belong to them.

The issue gained wider attention after reports surfaced regarding incorrect Physics answer sheets allegedly being uploaded for certain candidates.

Over 4 Lakh Students Apply for Answer Scripts

According to official figures released by Central Board of Secondary Education:

• 4,04,319 students applied for photocopies of answer scripts
• 11,31,961 answer books were requested
• 8,98,214 answer books have already been digitally furnished

The numbers indicate the large-scale concern among students regarding the evaluation process this year.

Re-Evaluation Window Opens Today

The re-evaluation process officially begins today for Class 12 students dissatisfied with their marks.

Students who accessed their answer scripts can now choose from:

• Verification of marks
• Re-evaluation of answers
• Both verification and re-evaluation

The board has advised candidates to carefully review their scanned answer copies before proceeding further.

Education Minister Comments on Re-Evaluation

Dharmendra Pradhan recently commented on the issue and suggested that approximately 20 percent of students may eventually apply for re-evaluation.

However, the final number will become clear only after the entire process concludes.

The ministry and board are reportedly monitoring the situation closely because of the unusually high volume of requests this year.

How CBSE Re-Evaluation Process Works

The re-evaluation process usually takes place in multiple stages.

Step 1: Obtain Photocopy of Answer Sheet

Students first request a scanned copy of their evaluated answer script.

Step 2: Verification of Marks

Students can request verification to ensure:

• All answers have been evaluated
• Marks have been correctly totalled
• Marks have been properly uploaded

Step 3: Re-Evaluation

Candidates can request re-checking of specific answers if they believe marks were incorrectly awarded.

The final revised marks, if any, are updated after the process concludes.

Concerns Raised by Students

Students and parents have raised several concerns this year, including:

• Transparency in digital evaluation
• Accuracy of uploaded answer sheets
• Technical reliability of the OSM system
• Delays in portal access
• Lack of clarity in grievance handling

Many students expressed anxiety over whether their original answer sheets were correctly evaluated.

Importance of the Re-Evaluation Process

The Class 12 board examination is considered crucial for:

• College admissions
• Competitive entrance applications
• Scholarship opportunities
• Career planning

As a result, students are particularly sensitive about evaluation accuracy and fairness.

The large number of answer script requests reflects the importance of trust and transparency in the board examination system.

CBSE Likely to Review Evaluation Procedures

Education experts believe the controversy may push Central Board of Secondary Education to further review and strengthen its digital evaluation procedures.

Possible improvements may include:

• Better answer sheet verification systems
• Improved scanning quality
• Enhanced portal stability
• Faster grievance resolution mechanisms

The board has not yet announced any major policy changes related to OSM.
