Delhi‑NCR tightened its Graded Response Action Plan after a late‑September review. On September 29, 2026, the Commission for Air Quality Management approved a revised GRAP that advances some curbs to earlier stages. Parents are asking about closures, masks and online classes today, October 2, 2026. These myth‑busters decode what actually changes.
What changed this week? GRAP’s schedule and enforcement were sharpened, but thresholds remain. Stage I starts at an Air Quality Index of 201, with stricter steps now moving earlier. Crucially, school or coaching decisions still require fresh government orders; Stage I alone does not trigger online classes.

Stage I intensifies dust, traffic and generator controls. It does not shift schools online. Hybrid or online classes have been ordered previously only through Directorate of Education circulars during Stage III and Stage IV escalations, and even then with specific class‑wise directions. Watch for new DoE or district orders, not assumptions.
Cloth or surgical masks do not reliably filter PM2.5. Use a well‑fitted particulate respirator such as N95, FFP2 or KN95. Avoid exhalation valves in classrooms or shared rooms, since valves let unfiltered breath escape and reduce source control for others. Fit matters as much as filtration.
Odd‑Even does not return automatically with any GRAP stage; it needs a separate Transport notification. Under higher stages, authorities may consider Odd‑Even, but it is optional. When Stage III or IV is invoked, Delhi’s Environment Department can order closure of schools, colleges and educational institutes, which covers coaching centres.
Each morning, check CPCB’s AQI and any CAQM/DoE orders, then adjust plans. CAQM has previously asked NCR to postpone physical sports competitions during peak months; use AQI to set outdoor intensity. For study rooms, use a HEPA purifier; pick a smoke‑CADR at least two‑thirds of room area.
| AQI band | Health message | Student action |
|---|---|---|
| 201–300 | Sensitive groups limit outdoor exertion. | Short, light outdoor drills only. |
| 301–400 | Respiratory risk rises for all. | Move sports indoors; use respirators. |
| 401+ | Severe exposure hazard. | Pause outdoor sports; monitor official orders. |
Bottom line for families today: follow official CAQM and DoE notifications, not rumours. Stage‑wise actions guide enforcement, but closures need written orders. Keep a non‑valved respirator in the bag, track AQI on the SAMEER app, and run a right‑sized HEPA purifier where students study.
