Beginning in 2026, five tests from the National Institute for Automotive Service Excellence (ASE) will be discontinued.
Starting in 2026, five certification tests from the National Institute for Automotive Service Excellence (ASE) will be suspended, according to a statement issued by the organization. December 31, 2025, will be the last day to obtain or renew the certifications that are being phased out as of January 1, 2026.
ASE stated that by eliminating some of the lower-volume tests, it will be able to free up resources to focus on areas that industry partners have consistently requested. “Individuals who wish to obtain or renew certification in these test areas should act now—and no later than December 31,” said Matt Shepanek, ASE Vice President of Certification Testing Programs.

ASE certification tests to be discontinued
The certifications granted by the National Institute for Automotive Service Excellence set quality standards for industry technicians. They are earned through specialized training and by passing exams that validate knowledge in vehicle repair and maintenance—both mechanical and electrical systems.
These certifications confirm the technical competencies of those looking to join or already working in the automotive industry. Holding ASE certifications not only improves job opportunities and earning potential, but also allows technicians to display an official seal in their workshops, boosting customer trust and attracting more business for employers.
However, due to increasing demand and the evolving nature of the industry, ASE has decided to retire certain certifications in order to make room for new ones that better address current sector needs. The following tests will be discontinued:
- Test E1: Truck Equipment Installation and Repair
- Test E2: Electrical/Electronic Systems Installation and Repair
- Test E3: Auxiliary Power Systems Installation and Repair
- Test P4: General Motors Parts Consultant
- Test X1: Exhaust Systems Specialist

ASE aims to keep certifications relevant and industry-aligned
The National Institute for Automotive Service Excellence noted that this decision followed a thorough review of test volumes, industry demand, and future priorities. As the transportation industry and fleet vehicle technologies rapidly evolve—particularly in the areas of electrification and advanced systems—ASE aims to stay up to date by offering certifications that are relevant and aligned with the sector’s current needs.
Dave Johnson, ASE President and CEO, stated that the institute continually assesses the need for new certifications to better serve both consumers and the automotive industry. “We are updating some of our basic automotive tests and will introduce new certifications focused on advanced vehicle safety and protection systems,” Johnson added.
For over 50 years, ASE has been a trusted and independent certification body for automotive professionals. Its certifications are widely recognized across the industry as a benchmark for technical knowledge and professionalism. For that reason, staying current remains a top priority for both the institute and the industry as a whole.
