The Certificate of Completion (CCL) in Engine Performance and Diagnosis program provides students the opportunity to learn the theory and practical skills necessary to service automotive vehicles. Will introduce students to the theory, diagnosis, and repair of engine performance systems in vehicles and help students gain insight into specific aspects of the automotive service industry. Courses in the CCL may include lecture and lab components to provide suitable classroom related material/theory, combined with hands-on learning experiences. Courses in the CCL are National Automotive Technicians Education Foundation (NATEF) accredited and aligned with the professional certification standards from National Institute for Automotive Service Excellence (ASE). This alignment can help prepare for ASE professional certification exams. The courses contained in the CCL can be combined with courses in other CCLs and be directly applied to the Associate in Applied Science (AAS) degree in Automotive Performance Technology.
