The Delhi High Court has requested responses from the Centre and the Central Board of Secondary Education (CBSE) regarding a petition filed by the National Students' Union of India (NSUI) that alleges significant irregularities in the on-screen marking (OSM) system for Class 12 examinations. The court has scheduled a hearing for June 12. The NSUI's petition calls for the reopening of the verification portal for one month, allowing manual rechecking of answer sheets and an independent inquiry into the alleged irregularities. The CBSE's on-screen marking system, introduced to enhance efficiency and transparency, has faced backlash due to numerous reported issues, including blurred scans and missing pages, leading to a drop in the overall pass percentage to 85.20%. The NSUI argues that the absence of a robust corrective mechanism adversely affects students as the academic calendar progresses amidst unresolved disputes. Additionally, the Delhi Government School Teachers' Association has urged the CBSE to reconsider the implementation of the OSM system, citing a lack of proper training for teachers.
