The National Institute for Automotive Service Excellence (ASE) is an independent, non-profit professional certification agency. ASE Automobile Technician certifications promote excellence in automotive vehicle repair and service. Certification requires two years of professional hands-on work experience, subject area mastery, and successful completion of difficult examinations. (Only two-thirds of technicians pass a subject exam on their first attempt.)
The ASE Master Automobile Technician certification requires mastery of all eight automotive subject areas. Worldwide, there are fewer than 100,000 ASE Master Automobile Technicians.
