Preparing students to learn, grow, thrive and achieve life-long success

Air Quality Resources


Solano school districts are committed to staying open to the extent possible to support student learning, working families, and student safety. However, districts understand that some parents may opt to keep students home due to poor air quality. In most instances, these absences will be excused, however parents should check directly with their school for information about possible excused absences.

Air quality conditions can change quickly, school districts may need to close schools during the school day, and parents should plan accordingly.

Schools will be closed if air quality reaches LEVELS 5 & 6 (Very Unhealthy & Hazardous levels with AQI Ratings of 200-500.) Districts may close schools during events with lower AQI LEVELS based upon factors like temperature, power outages, etc. All districts will communicate directly with parents.


Solano school districts follow guidelines and recommendations based on the United States Environmental Protection Agency (U.S. EPA) and Centers for Disease Control’s Air Quality and Outdoor Activity Guidance for Schools and Wildfire Smoke: A Guide for Public Health Officials.

The impact of smoke depends on the sensitivity of the person and the length of exposure, as outlined in the sample chart below. Children with respiratory or heart conditions are vulnerable to poor air quality and may require extra precautions. Parents are advised to consult with their family health care provider.
