On Wednesday, the Commission for Air Quality Management (CAQM) revised the Graded Response Action Plan (GRAP), mandating the closure of schools in Delhi and NCR districts under Stage 3 and 4 of the plan. 

An additional directive under Stage 3 of the GRAP also mandated the state government to stagger the timings of public offices and municipal bodies in Delhi and the aforementioned NCR districts.

Previously under GRAP-III, the state governments had the option to make decisions over halting physical classes for students up to Class 5 and transitioning to online learning.

Similarly, under Stage 4, they had the option to discontinue in-person classes for the students in classes 6 to 9 and 11.

However, the revised decision on the implementation of GRAP-IV mandates Delhi, Gurugram, Faridabad, Ghaziabad and Gautam Buddh Nagar to take these measures with NCR districts having the flexibility to decide.
