1. What is the L3 test?


The Light Duty Hybrid/Electric Vehicle Specialist (L3) is an advanced level certification from ASE. It is geared toward technicians who perform diagnosis and repairs on hybrid/electric vehicles.

2. How many questions are on the test, and how long do technicians have to take it?


The L3 test contains 55 questions (45 that are scored and 10 that are included for research purposes). Technicians will have 120 minutes (2 hours) to complete the test.

3. How much will the L3 test cost?


The L3 test fees are the same as other ASE Advanced Level tests.

4. Is there a work experience requirement to become L3 certified?


Yes. In addition to passing the L3 test, technicians must provide evidence of THREE years of hands-on working experience in auto maintenance and repair. Technicians can take the L3 test before they have the required experience, but they will not receive a certificate until they have submitted proof of work experience.

5. Is there a prerequisite requirement to become L3 certified?


Yes. In order to register for the L3 test, technicians must have previously passed both Automobile Electrical/Electronic Systems (A6) and Engine Performance (A8) tests.

6. Will there be a Composite Vehicle?


No. The L3 test will include a Certification Test Reference document that will identify the concepts for the hybrid/electric vehicle technology included in the L3 test. This document will be available as an electronic pop-up document during the test.

7. What is covered in the Certification Test Reference Document?


The information contained on the first page of the document outlines the common technical constructs for all of the hybrid/electric vehicle drive systems included in the L3 test. All questions in the test will follow this outline to ensure that the test content remains consistent and is understandable to technicians regardless of their area of hybrid/electric vehicle specialty. There are also block diagrams included that illustrate systems similar to those used in many hybrid/electric vehicles. These diagrams will serve as a visual reference and identify a vehicle classification for each of the platforms based on their technical characteristics. The vehicle classifications will be used in some of the test questions to define the specific hybrid/electric vehicle type referenced in the test question scenario. A "Glossary of Terms" is also included, and can be used as a reference if a term in a test question is not clearly understood due to differences in how the term is used by various hybrid/electric vehicle manufacturers.

8. Will the test questions cover product-specific technology?


The majority of the test questions will be generic, meaning the concept identified in the question should be applicable to most of today's hybrid/electric vehicles. There will be a number of questions that will only apply to the Type-1, Type-2 and Type-3 vehicle platforms identified in the block diagrams. Technicians will need to become familiar with the technology associated with all of these vehicle platforms, since questions about each of them may be included on the test. Please take the time to review all of the information contained in the Certification Test Reference before taking the test.

9. What test preparation information is available for the L3 test?


You can download The Official ASE Light Duty Hybrid/Electric Vehicle Specialist (L3) Study Guide (PDF). This guide contains the test specifications, task list, the Certification Test Reference Document, sample questions, and training resources.

10. Where is the L3 test given?


The L3 test will be given at Prometric test centers (including Satellite sites), just like other ASE tests.

11. Can I take other ASE tests at the same time as the L3 test?


Yes. Anyone who wishes to purchase additional tests may do so by paying the additional test fees.

12. Will I receive an insignia if I pass the L3 test?


Yes. If technicians pass the initial test and have provided the required work experience information, they will receive a certificate and insignia that identifies them as an ASE Certified Advanced Level Specialist.
