The exam consists of two parts： （l）instructor preparation, a competence-based instructor exam wasmultimedia theory tests; （2） a performance lesson for drivinginstruction and coaching. An implicit idea behind the innovated exam is that it can have a positive backwash effect on the quality ofdriver instructor preparation programs. This study aims to evaluate the reliability, validity and fairness of the theoretical tests, whichappear in different versions for successive groups of PDIs （prospective driving instructors）. Data of 4,741 PDIs, enrolled during theperiod between January 2010 and October 2012, were used for analysis. The results of psychometric analyses show that the theory testsyielded reliable and fair decisions about instructor certification. The predictive validity of the theory tests for the final performanceassessment was low. Implications for the design and on-the-fly maintenance of exam item banks are discussed. Follow-up studies willfocus on the question, whether the improved instructor exam produces safer drivers in the end.
