Quick Facts

About the Automotive Technician Certificate

The purpose of this certificate program is to prepare students with the technical skills to obtain direct employment in the automotive industry and to upgrade the skills of individuals already employed in the industry. The courses within this certificate program prepare students for the National Automotive Service Excellence certification examinations which are required for most entry-level employment opportunities in the industry. Upon completion of each course, the student will receive an Award of Completion which will identify the competencies achieved.

Note: National Automotive Service Excellence (ASE) certification is essential to individuals preparing for positions in the automotive industry. ASE certification requires hands-on working experience as well as completion of written examinations. Two years of posthigh school educational training, such as that offered in the automotive certificate and degree programs at Yavapai College, may be substituted for up to one year of the hands-on work experience requirement of the ASE certification.

Program Outcomes

Upon successful completion of the Automotive Technician Certificate program, the learner will be able to:


  1. Identify, diagnose and repair problems with internal combustion engines. (AUT 108)
  2. Diagnose and repair basic electrical problems. (AUT 100, AUT 109)
  3. Remove and replace friction brake pads, friction brake shoes, and bleed a hydraulic system. (AUT 123)
  4. Identify major components of the automotive suspension and steering system. (AUT 126)
