AirKnowledge is a partnership training program in EPA’s Office of Air Quality Planning and Standards (OAQPS). AirKnowledge develops training material to assist EPA, tribal, state, and local air agency staff in implementing aspects of the Clean Air Act managed through OAQPS. AirKnowledge also works with partners to create trainings for this audience.

The trainings on this website are arranged by eight curricula (subject areas): a foundational Air Pollution Basics curriculum and seven curricula that relate to particular job functions within air quality agencies. We have labeled the trainings to help you understand who created these trainings:

AirKnowledge content (as indicated with the AirKnowledge logo) is all new training content developed by AirKnowledge since 2020 (modules and courses).


AirKnowledge legacy content is all training content developed by AirKnowledge prior to 2020 (modules and courses) that is dated but is still technically sound and relevant to the program curricula.


Partner-developed content is content developed by AirKnowledge partners that is relevant to the program curricula.


EPA-developed content is content developed by EPA outside of AirKnowledge that is relevant to the program curricula.



To browse training, click on “eLearning” or “Classroom Course Materials.”

State, local and tribal air agency users should use the Learning Management System (LMS). While the same training content is available on the website and LMS, the LMS maintains student records which some state, local, and tribal air agencies may require of their employees.
