ImageObjective:  To identify those technicians who possess knowledge of the skills required to diagnose sophisticated driveability and emissions-related problems on automobiles, SUVs and light-duty trucks.

Scope of Program:  The Advanced Engine Performance Specialist (L1) Test consists of questions that test technicians' knowledge in the diagnosis and repair of computer-controlled engine systems. In addition, the test measures technicians' abilities in diagnosing the cause of high-emission failures. This is especially important in states where basic I/M (inspection/maintenance), enhanced I/M (ASM or IM240), and OBD testing programs are in effect.

Test Development: The questions that appear on the Advanced Engine Performance Specialist Test were written by industry experts familiar with all aspects of driveability and emissions diagnostics. Many of the questions relate to a sample vehicle using a composite powertrain control system. It represents a cross section of computerized engine control technology used by most manufacturers. This assures an equal opportunity for all technicians who take the test, without bias towards any specific manufacturer.

Format:  The scored portion of the test consists of 50 multiple-choice questions that address six content areas: General Powertrain Diagnosis, Computerized Powertrain Controls Diagnosis (including OBD II), Ignition Systems Diagnosis, Fuel Systems and Air Induction Systems Diagnosis, Emission Control Systems Diagnosis, and I/M Failure Diagnosis. The test may include additional questions that are included for statistical/research purposes and don't affect the test score. Some of the questions require extensive use of the Composite Vehicle Type 3 Reference Booklet that is provided both before and at the time of testing. Because of this, ASE recommends that technicians NOT register for other tests during the same test session.

Prerequisite:  Those registering for the Advanced Engine Performance Specialist Test must be currently certified in the regular Engine Performance (A8) category, and satisfy the two-year hands-on experience requirement.

Certification Requirements: To become ASE certified as an Advanced Engine Performance Specialist, technicians must be currently certified in A8 and pass the Advanced Engine Performance Specialist test.

Recognition: Those who earn L1 certification will be issued wallet and wall credentials, plus an appropriate sleeve insignia and a special toolbox medallion. They will also receive ASE’s Blue Seal Tech News.

Recertification: To remain certified, technicians must be retested every five years.  This requirement allows these automotive professionals to show that they are staying current with changes in the industry.  Those registering for the L1 recertification test must be currently certified in A8.

Fees: There is a $32 non-refundable registration fee per person, plus a $52 test fee for the L1 test. There is a $70 registration fee and a $74 test fee to take the computer-based L1 test.  All computer-based testing fees are non-refundable.

Registration: The Advanced Engine Performance Specialist test is available in either Paper/Pencil or Computer-Based Testing format.
