The need to document warfighting readiness and training effectiveness is a major concern for warfare sponsors, operational commands and training system developers. The Electronic Warfare Continuum Assessment Program (EWCAP) is a low cost method for rapid evaluation of electronic warfare (EW) readiness and training effectiveness across the careers of Naval Aviation personnel. EWCAP provides documentation of EW performance and training deficiencies, and recommends solutions to identified training deficiencies. To produce a snapshot view of EW knowledge and skills, microcomputer-based tests have been developed and administered to the EA-6B, E-2C, F/A-18, and A-7 communities, and are in development for the S-3, A-6 and F-14 communities. Repeated testing of each platform determines whether changes implemented in the training cycle significantly impact operational performance. Each test is carefully constructed to offer maximal training benefits through the use of extensive instructional feedback. Fleet response to the EWCAP for both training and testing has been overwhelmingly positive.
