An Evaluation of California’s Commercial Driver License Drive Test

By: Nancy Clarke

The federal government requires states which permit third-party testing of commercial drivers to determine whether these tests are equivalent to those given by the state driver licensing authority. To meet this requirement, the California Department of Motor Vehicles (DMV) plans to sample commercial driver license (CDL) applicants tested by their employer, retest them at DMV, and compare the fail rates for the employer and DMV tests to determine if they are equivalent in difficulty and reliability. In order to make this determination, it is necessary to estimate the reliability and other psychometric properties of the California DMV CDL test. Without this information, it is not possible to determine whether differences between the DMV and employer test exceed what would be expected from repeat administration of the CDL test by DMV.
