CBSE Class 12 Evaluation Issues 2026: OSM System, Low Marks and Board Response

The CBSE Class 12 evaluation issues 2026 have become a major topic of discussion among students and parents after the declaration of results. Many candidates have raised concerns about unexpectedly low marks in key subjects, linking the issue to the newly implemented On-Screen Marking (OSM) system used for digital evaluation.

CBSE has responded to these concerns, stating that the system is designed to improve transparency and accuracy in marking. However, the debate continues as students report inconsistencies in their scores and request re-evaluation.

CBSE Class 12 Evaluation Issues Linked to OSM System

The main reason behind the CBSE Class 12 evaluation issues is the introduction of the OSM (On-Screen Marking) system for the 2026 board exams. Under this system:

• Answer sheets are scanned and uploaded digitally
• Examiners evaluate answers on computer screens
• Marks are calculated and recorded automatically
• Physical checking of answer sheets is removed

According to CBSE, this system reduces human error and speeds up evaluation. However, teachers and students have reported concerns such as blurred scanned pages, missed answers, and screen-related fatigue during evaluation.
