CBSE Class 12 result row: AI not used in evaluation, says board
As questions over the accuracy of CBSE Class 12 board results intensify, School Education and Literacy Secretary Sanjay Kumar addressed the growing controversy around CBSE's newly introduced On-Screen Marking (OSM) system.
“Errors were identified in the evaluation process. Out of nearly 98 lakh answer sheets assessed, around 13,000 required correction and further review, as the On-Screen Marking (OSM) system could not adequately process them. These cases were subsequently examined through a manual checking process,” said Education Secretary Sanjay Kumar.
Amid concerns over the CBSE Class 12 evaluation process, Kumar defended the board’s On-Screen Marking (OSM) system, saying it was introduced to improve transparency and standardisation.
“Student concerns are the main focus. The technology was not ready in 2014, but now it has been reintroduced. ICAI, IB and Cambridge also follow similar systems,” he said.
Kumar also highlighted the measures taken by the Education Ministry during the evaluation process, stating that a three-layer security mechanism was in place for the assessment of answer sheets.
The clarification comes after several students alleged low marks, unchecked answers and discrepancies in the CBSE Class 12 2026 board results, triggering criticism of the digital evaluation process.
CBSE announced a multi-stage review mechanism for students seeking corrections.
REEVALUATION FROM MAY 19
CBSE said students can apply for scanned copies of evaluated answer sheets from May 19 to May 22 before seeking verification or re-evaluation.
Key points:
Review process: Students can first access answer sheets, then apply for verification or re-evaluation.
Fees: Rs 100 per answer sheet copy and Rs 25 per question. Fees will be refunded if marks increase after review.
Evaluation scale: Around 98.6 lakh answer sheets were checked this year. About 13,000 copies had errors and were manually reviewed later.
Teacher training: Around 77,000 teachers evaluated papers after training on marking patterns and previous papers.
On-Screen Marking (OSM): CBSE said every answer is checked individually under the digital system.
Initial issues: Officials admitted there were glitches during the rollout but said they were later fixed.
No AI used: CBSE clarified that artificial intelligence was not used in evaluating answer sheets.
Future plans: The board said OSM will continue, adding that only standardisation has changed, not the assessment process.
The board’s response is likely to remain under focus as many students depend on Class 12 marks for college admissions.
