State and local air quality officials receive training on air pollution from a number of training providers. EPA provides training to state and local air agencies via self-instructional courses, webinars and through classroom course materials (known as the Air Pollution Training Institute, APTI). Regional state organizations focusing on air quality issues develop and hold training courses, through classroom courses, workshops, conference and webinars. California’s Air Resources Board is a major training provider and has developed its own curriculum of courses. A number of international air pollution control organizations provide general and specialized conferences addressing air quality management, such as the Air and Waste Management Association. Many universities (both in the U.S. and abroad) offer courses and degrees in environmental management, with an emphasis on air pollution.
