Objective: To identify and recognize those technicians who can demonstrate knowledge of the skills necessary to diagnose, service, and repair compressed natural gas vehicles.

Scope of Program: The ASE Compressed Natural Gas Vehicle (F1) Test contains questions on vehicle inspection, equipment installation, leak testing and repairs, emissions, system diagnosis, maintenance and repair, and cylinder safety.

Test Development: The questions that appear on this test are written and approved by a cross section of industry experts that includes working technicians, vocational educators, aftermarket parts and equipment manufacturers, and representatives from automobile manufacturers both foreign and domestic. This procedure ensures that the tests are fair for all technicians without bias towards any specific automobile manufacturer.

Format: The scored portion of the test consists of 55 multiple-choice questions that address various content areas. The 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: In order to earn ASE certification, technicians must pass the CNG exam and present proof of at least two years of relevant work experience. 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 newsletter.

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

Fees: There is a $36 non-refundable registration fee per person and a $28 test fee for each test when taken in the paper/pencil format.

Registration: The Compressed Natural Gas Vehicle test is available in Paper/Pencil test format only. The tests are offered every May and November at over 700 test centers nationwide. Click here for more information on registering for tests.
