The National Students’ Union of India (NSUI) has moved the Delhi High Court by filing a Public Interest Litigation (PIL) challenging the implementation of the Central Board of Secondary Education's (CBSE) newly introduced On-Screen Marking (OSM) system for evaluation of Class 12 board examination answer sheets.
The OSM system is a digital evaluation method where physical exam papers are scanned, digitally masked to hide students' identities, and evaluated by teachers on a computer screen.
