The National Institute for Automotive Service Excellence (ASE) is retiring five of its certification and recertification tests on December 31, 2025.

The following tests will be discontinued:

  • E1: Truck Equipment Installation and Repair

  • E2: Electrical/Electronic Systems Installation and Repair

  • E3: Auxiliary Power Systems Installation and Repair

  • P4: General Motors Parts Consultant

  • X1: Undercar Specialist Exhaust Systems

Once the clock strikes midnight on New Year’s Eve, these tests will officially be off the table, both for first-time certifications and recertifications.

“Those individuals who want to be certified or recertified in these test areas should act now and definitely no later than Dec. 31,” said Matt Shepanek, vice president of credential testing programs at ASE. “ASE is constantly being asked by industry partners to create new credential tests. By retiring some of the lower volume tests, we can free up resources to work on some of these new requests.”

ASE noted that the decision follows a review of test volume, industry demand, and future priorities. With technology in fleet vehicles and work trucks moving at full speed, especially when it comes to electrification, safety, and advanced driver-assistance systems, ASE is aiming to keep its offerings fresh, relevant, and focused on today’s technician needs.

“Along with transportation industry leaders, we continuously evaluate the need for new and existing certifications to best serve consumers and the industry,” said Dave Johnson, ASE president and CEO. “We’re also in the process of updating some of our core automotive tests and will be introducing new certifications focused on advanced vehicle safety and security systems.”

For more than 50 years, ASE has served as a trusted, independent credentialing body for automotive professionals, including those working in fleet operations, truck equipment, and repair shops across the U.S. ASE certification is recognized throughout the industry as a gold standard for technical knowledge and professionalism. That blue seal still carries a lot of weight.

Bottom line? If one of these five test areas applies to your role or shop, don’t wait until the last minute to register. You’ve got until December 31, 2025, to lock it in.
