The National Institute for Automotive Service Excellence (ASE) is a professional certification group that certifies professionals and shops in the automotive repair and service industry in the United States and parts of Canada.

It is an independent, non-profit organization created in 1972[1] in response to consumers needing to distinguish between potentially incompetent and competent automotive technicians.

[3] These involve several exams, the passing of which, added with two years of relevant hands-on work experience, will merit certification.

ASE certification is usually required by employers for those interested in pursuing a career in professional automotive service.

[7] Some municipalities require ASE certification in order to be licensed for motor vehicle repairs, such as Broward[8] and Miami-Dade[9] counties of Florida.
