An automotive professional can demonstrate a high level of specialized knowledge and advanced skill by becoming certified by the National Institute for Automotive Service Excellence. ASE Certification is beneficial in a number of ways – it may qualify technicians for career advancement and demonstrates one’s commitment to continuing education and skills development.
ASE Test Series
There are 14 ASE test series, each covering a particular area of certification. These tests are written and approved through a rigorous test-creation process by industry professionals. In order to be certified in any series, you must pass one of the tests in your chosen series and demonstrate that you have at least two years of work experience related to that series. In many cases, it is necessary for you to re-take the test every five years in order to maintain certification. Each test has between 40 to 70 questions that are scored. There may be additional questions that are not scored.
