Between skies filled with wildfire smoke and the respiratory health concerns associated with the COVID-19 pandemic, air quality has never been more relevant to school districts. When air quality is poor, education officials find themselves confronted with a difficult decision: do we alter school operations to protect student health?

In this guide, you will learn:

  • How to reduce absences and protect student health
  • How to improve academic performance
  • How to make better decisions with real-time air data

Why outdoor air quality matters to school districts?

While indoor air quality is a common topic of discussion for school administrators, outdoor air quality is rarely considered except during periods of extreme air pollution. Outdoor air quality also has a significant impact on school district operations, however, and can often be managed more cost-effective.

How does your campus protect students from air pollution?

Vanessa O'Brien

Senior Sustainability Officer at Lincolnshire City Council

It has been great to be able to work with such a large number of students and share live local air quality data with them. All the schools have seen the benefit in understanding what the data is telling them, and how this can be used to inform decisions about how and when to travel.

"People want to know what’s really happening with their local air quality. The ability to have an answer back to students, parents, and teachers within seconds is invaluable."

We work mainly with the local authorities for deploying the Node-S devices — with the local council. The community has been really helpful and has made a big difference. The majority of the Nodes are up on street lamps around the town.

"Having real-time, very hyper-local data about the air quality where you are spending your time has great potential to impact people, in terms of the decisions they make, but also in terms of making that connection between the environment and health."

Class Teacher, Sierra Waldorf Elementary School

"Having the sensor on site is great for our school and a nice service to offer our surrounding community. Our device went in about 3 years ago and is working great! It is so important for us to know our air quality. Whenever it hits unhealthy levels, we keep our students inside. The data is available right on my phone, so I can check it ahead of recess and make a real-time decision on whether to send students outside or keep them on an indoor activity schedule when air quality is over the threshold. "

Superintendent/Principal, Pope Valley USD

“We chose Clarity because they provided up-to-date, local, scientifically-backed, and relevant data to make decisions about whether to keep students inside. Because of the geography and demographics in our county, the official air monitoring stations are about an hour away with hills in between, providing irrelevant data. We would have poor air quality and the official stations would be cleared; or the official stations would show heavy particulate levels and we would have clean air."
