Here are three links to aid in researching whether schools are healthy

Healthy Schools Campaign, an independent not-for-profit organization, is the leading authority on healthy school environments and a voice for people who care about our environment, our children, and education.
Our mission is to advocate for policies and practices that allow all students, teachers and staff to learn and work in a healthy school environment.

Healthy Schools Network, Inc. is a 501 c3 national environmental health organization that does research, information, education, coalition-building, and advocacy to ensure that every child has a healthy learning environment that is clean and in good repair. Founded in 1995,we have documented and publicized school environmental problems; shaped and won new education, health, and environmental policies; fostered dozens of local and state policy groups; won systemic federal and state reforms; and helped thousands of parents and schools make classrooms and buildings healthier through our EPA award-winning Healthy Schools/Healthy Kids Clearinghouse (Information and Referral Services). Major efforts include: building the platform and the forum for school environments through the collaborative Coalition for Healthier Schools which we founded and convene with more than 400 local, state, and national partners; leading National Healthy Schools Day; offering steady assistance through the Clearinghouse's publications and referrals; and refining our model New York Program. Throughout, we are focused on: 1) High Performance School Design/Construction consistent with children's needs for healthy environments; 2) Greening Existing Schools; and 3) Environmental Public Health for Children who are disproportionately affected by environmental exposures.
