The National Institute for Automotive Service Excellence offers online practice tests on its website for a fee, allowing auto mechanic candidates to assess their certification test readiness. As of September 2015, the practice tests are for ASE Automobile Tests A1 to A8 and Auto Parts Test P2 only.
The practice tests are half the length of the official certification tests but contain similar questions. There is only one version of each practice test. To take advantage of a practice test, a candidate needs to purchase a voucher for about $15, with discounts available for purchasing multiple vouchers. The voucher gives the candidate a 60-day access code to a practice test. The voucher can only be used once and is non-transferable.
