The National Institute for Automotive Service Excellence (ASE) is a non-profit professional certification group that provides professional certification to those in the automobile repair and service industry throughout the United States as well as parts of Canada. 

ASE Certification is granted to automotive professionals who have gained at least two or more years of relevant work experience in their field and passed the requisite ASE certification test. ASE certification provides an automotive professional with a shoulder insignia bearing the ASE logo, an ID card for their wallet, and a framed certificate for his or her shop. These items convey trustworthiness and professionalism to automotive customers, so utilization of available ASE practice tests and other resources is vital for any automotive professional.
