ASE launches maintenance and light repair certifications

The National Institute for Automotive Service Excellence (ASE) has launched a new certification test aimed at those technicians primarily involved with vehicle maintenance and light repair services. The Auto Maintenance and Light Repair (G1) test is now available as part of the ASE certification program. The new test was developed in response to requests from the industry for a certification category aimed at technicians performing scheduled maintenance and common bumper-to-bumper repairs. Registration for the new Auto Maintenance and Light Repair certification test is now available, with testing in July and August. 

"Since about 70 percent of all work being performed in repair shops across the nation is maintenance-based, this new test category will focus on the knowledge necessary to successfully perform the most common maintenance and light repair tasks," said Tim Zilke, ASE president and CEO. "If you are a technician performing maintenance and light repair services, the new ASE Maintenance and Light Repair (G1) certification is for you." 

Developed by industry experts and the certification professionals at ASE, the Auto Maintenance and Light Repair is somewhat different from the other ASE certifications. The new test will have a one year requirement of hands-on work experience in maintenance and light repair to qualify, and half of that requirement may be met by appropriate vocational training.

It will also have a unique, smaller shoulder patch. However, like all other ASE certifications, the credential will be valid for five years and will be available through the more than 400 ASE testing locations across the country. Upon passing the G1 test, a technician will receive a shoulder insignia, display certificate and wallet card. 

The new G1 certification provides an assessment of an individual's technical knowledge of bumper-to-bumper maintenance and light repairs in the critical areas of engine systems, automatic transmission/transaxle, manual drive train and axles, suspension & steering, brakes, electrical and heating & air conditioning. There are 55 scored questions on the test, plus 10 unscored research questions, and those taking it will have an hour and a half (90 minutes) to complete it. The questions, written by service industry experts familiar with all aspects of maintenance and light repair, are entirely job-related. Like any other ASE certification, G1 tests the things you need to know to do the job.  Theoretical knowledge is not covered. 

You can download a free copy of the Maintenance and Light Repair (G1) Study Guide on the ASE website at The Study Guide contains the Test Specifications and the Task List to provide you with a map of the topics that will be covered on the test.
