The National Institute for Automotive Service Excellence (ASE) has released four practice tests for the medium/heavy truck series.

The new tests cover the specialty areas of the diesel engines (T2), brakes (T4), electrical/electronic systems (T6) and preventive maintenance inspection (T8) tests.

ASE says practice tests for the remaining four tests in this series will be available later this year.

The ASE practice tests, delivered exclusively online, are half the length of the corresponding ASE certification test and are formatted to look and feel like actual certification tests. The practice questions are developed using the same methods as actual ASE questions. Each practice test question has answer explanations, a great tool for helping technicians prepare for the ASE certification tests.

The National Institute for Automotive Service Excellence was established in 1972 as a non-profit organization to help improve the quality of automotive service and repair through the voluntary testing and certification of automotive technicians and parts specialists.

Today, there are approximately 300,000 ASE-certified professionals at work in dealerships, independent shops, collision repair shops, auto parts stores, fleets, schools and colleges throughout the country. In addition, over 50,000 students currently hold ASE student certification credentials.
