NEW DELHI – The Delhi government on Monday directed schools to transition all classes for students up to Class 5 to online mode. This decision follows a severe deterioration in air quality across the national capital.
The Directorate of Education issued a circular enforcing the new directive. Physical classes for students from nursery to Class 5 are suspended immediately and will remain so “until further orders.” This mandate applies to all government, government-aided, and unaided recognized private schools within Delhi.
Mandate for Junior Classes Amid Pollution Surge
This latest order modifies earlier guidelines issued by the education department. Previously, schools operated in a hybrid mode for various grades. However, the current health emergency from pollution necessitates that younger students, identified as more vulnerable to respiratory issues, receive instruction exclusively online. The aim is to minimize their exposure to hazardous outdoor air.
Students in Class 6 and above will continue attending school under the established hybrid model. This involves a combination of in-person attendance and remote learning. The guidelines for these older grades remain consistent with the directives issued on December 13.
Delhi’s Air Quality Hits ‘Severe’ Levels
Delhi frequently grapples with severe air pollution, especially during colder months. The city’s Air Quality Index (AQI) registered 427 on Monday, categorizing the air quality as ‘severe.’ The previous day, Sunday, recorded an even higher AQI of 461 . This figure marked the second highest December AQI on record, indicating a significant and rapid decline in air quality.
Data from the Central Pollution Control Board (CPCB) highlighted the extent of the crisis. On Monday, 27 monitoring stations across Delhi reported ‘severe’ air quality. Another 12 stations indicated ‘very poor’ conditions. Wazirpur recorded the most polluted air, with an AQI reaching 475 .
Health Risks Associated with Poor Air Quality
A ‘severe’ AQI poses substantial health risks to the entire population, particularly children. Exposure can lead to or worsen respiratory illnesses, including asthma. Symptoms like coughing, throat irritation, and shortness of breath become common. Public health officials typically advise against outdoor physical activity and recommend protective measures like masks during such conditions. The government’s decision to shift junior classes online directly addresses these immediate health concerns for young students.
Understanding the Air Quality Index (AQI) Categories
The AQI provides a clear, standardized measure of air quality and its potential health impacts. Citizens can use these categories to understand daily pollution levels.
| AQI Range | Category | Associated Health Impact |
|---|---|---|
| 0-50 | Good | Minimal impact. |
| 51-100 | Satisfactory | Minor breathing discomfort for sensitive people. |
| 101-200 | Moderate | Breathing discomfort for people with lung/heart diseases, children, and older adults. |
| 201-300 | Poor | Breathing discomfort for most people on prolonged exposure. |
| 301-400 | Very Poor | Respiratory illness on prolonged exposure. Affects healthy people, seriously impacts those with existing diseases. |
| 401-500 | Severe | Respiratory effects even on healthy people. Serious health impacts for people with existing diseases. May cause respiratory illness even with light physical activity. |
Outlook for School Operations
The online learning directive for junior school children remains in effect indefinitely. Delhi government and education authorities will continuously monitor air quality levels. Resumption of physical classes will depend on a sustained improvement in the AQI to safer, healthier categories. Parents and students should rely on official school and government channels for updates regarding class modalities.
