Frequent Questions

Are there statistical data available regarding IAQ in schools?

In 2002, EPA conducted a survey of public and private schools across the country to determine the extent to which these schools are implementing IAQ programs. The results of the survey indicate that 42 percent of schools in the U.S. have an IAQ management program in place (about half of those schools use the IAQ Tools for Schools Program). Survey respondents said that their IAQ programs have led to improved workplace satisfaction, fewer asthma attacks, fewer visits to the school nurse, and lower absenteeism.

According to a  2000 U.S. Department of Education National Center for Education Statistics report, about 25 percent of U.S. schools need extensive repair or replacement of one or more buildings. Nearly 11 million students attend these schools. Improper building operations and deferred maintenance contribute to poor indoor environmental conditions. About 40 percent of schools report at least one unsatisfactory environmental condition such as poor ventilation, heating or lighting problems, or poor physical security.
