What organization provides fire prevention courses on a national level and include courses of fire inspection principles, fire prevention specialist, code management, plans review for inspectors, and fire/arson investigation?

The answer is the NFA or the National Fire Academy.

Explanation:

The NFA is a part of FEMA, the Federal Emergency Management Agency and they work to train fire and emergency services personnel to handle fire and other emergencies more effectively. They provide free courses and programs at their Emmitsburg, Maryland campus and online and periodically set up training courses in other parts of the country.  You can take courses with the NFA if you are employed in fire prevention and control, Emergency Medical Services, or fire-related emergency management activities. It operates out of the NETC campus that was formerly Saint Joseph College which closed in 1973.
