Update on Schools Response to Poor Air Quality
![air quality index guide](https://www.campbellusd.org/image.php?width=888px&image=/news/air-quality-update.jpg)
At this time, Campbell Union School District's and other schools in Santa Clara County are not closing.
Based on guidance from Santa Clara County Public Health, the Environmental Protection Agency (EPA), and Centers for Disease Control (CDC), we have elected to use a threshold of a 275 air quality index (AQI) to determine when to close our schools. We will be monitoring air quality through www.airnow.gov and informing schools and after-school programs of the guidelines and recommend that families stay informed and be mindful of health concerns.
A joint letter from our Superintendent and the County Superintendent of Schools has more details. It is available online and are emailing it to families via our mass notification system.
