Applicants for FAA Certificates are tested in a three step process: a computer based knowledge test, an oral examination and a flight test. The first two stages test applicants' theoretical understanding, and the third concentrates on flight skills and practical application.

This balance helps to underscore the importance of theoretical materials in flight training. Applicants at every level are expected to master a large amount of specialized data intended to increase competence and safety.

This process is best supported by formal ground schools. These cost-efficient forums are aimed at providing students with all the theoretical information needed to explain and amplify principles of flight.
