Service operations looking to renew or enhance their technical prowess can use National Institute for Automotive Service Excellence (ASE) T-Series certification tests to verify the proficiency of professional service technicians who work on medium- and heavy-duty trucks.
“The ASE medium and heavy-duty truck certification exams allow service professionals to demonstrate to employers and customers that they possess the skills and expertise needed to service and repair trucks across all class levels,” says Dave Johnson, president and CEO of ASE. “Passing these rigorous ASE truck certification exams give technicians the confidence of knowing they rank among the best in their field.”

Designed to identify and recognize medium and heavy-duty truck technicians who demonstrate knowledge of the skills necessary to diagnose, service and repair different systems of Class 4 through Class 8 trucks and tractors, ASE offers eight T-Series certification tests. The tests include gasoline engines (T1); diesel engines (T2); drive train (T3); brakes (T4); suspension and steering (T5); electrical/electronic systems (T6); heating, ventilation and air conditioning (HVAC) (T7) and preventive maintenance inspection (T8). Those who are certified in tests T2–T8 are recognized as ASE Certified Master medium-heavy truck technicians.
ASE offers a free, online study guide that contains test specifications, tasks lists, sample test questions and training resources.
