Once inside, most establishments proudly display the ASE certificates earned by their technicians in their office or waiting room. Finally, the technicians may be wearing an ASE patch on the shoulder of their uniform or a pin above their nameplate. All ASE-Certified professionals are proud of their achievement and are more than willing to show you their credentials. ASE has years of experience helping the automotive industry verify the skills and knowledge of the technicians working at dealerships, independent repair shops, collision shops, franchises, fleets, and more. Car owners and the service and repair industry regard ASE certification as the standard measure of competency and a guide to quality auto repairs.ASE has taken this responsibility one step further by recognizing highly qualified repair facilities and allowing them to showcase their technicians and their commitment to excellence. It is called the Blue Seal of Excellence Recognition Program. The Program's emphasis is to identify establishments having at least 75% of their staff be ASE-Certified professionals. It is a program for businesses striving to be the best and willing to prove their commitment. Certified Transmissions, Inc. earns this certification with 100% of its full time staff ASE Certified.
