Abstract: A flight school credentialing and verification system uses software tools to implement flight school functionality, including scheduling flight course sessions, customizing flight course sessions, and integrating third party tools, all in accordance with safety requirements as established by a regulatory body. For example, a flight school credentialing and verification software application may determine whether credential items of a user satisfy credential definitions defined for a flight course. Responsive to a determination that the credential items satisfy the credential definitions, an availability of one or more resources of a flight school used for the flight course can be verified, and, responsive to that verification, one or more candidate flight course registrations are determined. A flight course output indicative of a selected flight course registration is then generated.
