Toyota Technician Training & Education Network (TTEN), AAS

At Dunwoody College of Technology, the Toyota T-TEN program prepares graduates to be technicians servicing Toyota and Lexus vehicles at authorized dealerships. Students train specifically on current model Toyota and Lexus vehicles, information systems, scan tools, and training materials. Students also complete an internship under the guidance of a master technician at a sponsoring Toyota or Lexus dealership. These paid internships give students the opportunity to integrate their learning and further develop their skills in service technology.

Arts & Science curriculum supports the technical skills students learn as well as enhance students’ oral and written communication skills.

All T-TEN instructors are certified by Toyota in the areas that they teach, in addition to being certified as Master Technicians by the National Institute for Automotive Service Excellence (ASE).

Dunwoody has received recognition from Toyota for being one of the best T-TEN automotive schools in the nation and is a Chassis, Electrical, Engine, Drivability (CEED) School, the highest level for a T-TEN school.
