ASE Engine Machinist Test Series

Objective: To identify and recognize those engine machinists who can demonstrate knowledge of the skills necessary to professionally machine and assemble gasoline and diesel engines used in automobiles and trucks.

Scope of Program: The Engine Machinist Series includes three tests: Cylinder Head Specialist, Cylinder Block Specialist, and Assembly Specialist. Candidates will be tested on the tasks associated with the teardown, cleaning, inspection, repair, machining, and reassembly of both gasoline and diesel engines. Each test candidate can choose to be tested on a single discipline, or on all three.

Test Development: The questions that appear on these tests are written and approved by a cross section of industry experts familiar with the engine rebuilding industry. They are entirely job-related. They are designed to test the knowledge of the skills machinists need to possess in order to be effective professionals. The questions are written to deal with practical problems encountered in day-to-day work situations.

Format: The scored portion of each test consists of approximately 55 to 60 multiple-choice questions that address various content areas. Each test may contain up to ten additional questions that are included for statistical research purposes only. Answers to these questions do not affect test scores, but since they are not separately identified in the test, all questions should be answered.

Certification Requirements: To become ASE certified, machinists must pass one or more of the Engine Machinist tests and present proof of at least two years of relevant, verifiable work experience. Those who pass all three tests are recognized as ASE-certified Master Engine Machinists. Technicians may substitute two years of relevant formal training for up to one year of the work experience requirement.

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

Recertification: To remain certified, machinists must be retested every five years. This requirement ensures ASE-certified machinists are staying current with changes in the industry.

Fees: There is a $32 non-refundable registration fee per person and a $26 fee for each test when taken in the paper/pencil format.

Registration: The Engine Machinist test series is available in Paper/Pencil test format only.  The tests are offered every May and November at over 700 test centers nationwide.  Click here to register online for the Paper/Pencil tests.
