Existing indoor air quality (IAQ) policies for schools reflect the variety of institutional, political, social, and economic contexts that exist within individual states. The purpose of this report is to provide a better understanding of the types of policy strategies used by states in addressing general indoor air quality problems. The policies discussed illustrate approaches that states can consider when developing legislation, regulations, guidance documents, and programs to create healthier indoor environments in schools. The report provides detailed information on existing policies, with an emphasis on policy strategies aimed at preventing indoor air quality problems. Thus, the report focuses on policies that promote better maintenance and management of existing school facilities, as well as better design and construction practices in new and renovated schools. Additionally, since an IAQ policy has little value unless implemented, the report highlights significant implementation activities and notes potential strengths and weaknesses of individual policies in this regard.
