Summary
This 1977 final report, prepared by INNOVATRIX, Inc. for the National Highway Traffic Safety Administration (NHTSA), details the development of a comprehensive training curriculum for motor vehicle license examiners. The project was motivated by the need to standardize the identification of applicants with physical or mental conditions that could impair driving safety, a requirement under National Highway Safety Program Standard No. 5. Prior to this study, medical screening methods varied significantly across states, lacking objective methodology. The goal was to equip layperson examiners with the skills to detect signs of impairment and determine when to refer applicants for professional medical evaluation. The development process began with a job analysis involving literature reviews, consultant input from the American Medical Association (AMA) and the American Association of Motor Vehicle Administrators (AAMVA), and direct observation of examiners. Researchers identified four core job functions: reviewing records, detecting signs/symptoms, selecting a course of action, and reporting findings. A critical component was the reduction of an initial list of 263 medical signs and symptoms to a manageable list of 51, refined through consultation with physicians to ensure reliability for lay observers. The curriculum was structured into 13 instructional units divided into medical content (covering cardiovascular, neurological, ophthalmological, and mental/emotional systems) and task-related skills (screening methods, interviewing, and record usage). A key output was the "Medical Evaluation Checklist" (MEC), a performance aid using decision rules to guide referrals based on "automatic" severe symptoms or clusters of lesser symptoms. The curriculum was pilot-tested in Madison, Wisconsin, with 17 trainees from the Wisconsin Division of Motor Vehicles. Pre- and post-training assessments using a Course Evaluation Instrument demonstrated significant learning gains. Trainees improved from an average of 17 correct answers out of 35 to 24 correct answers, representing a 41% improvement over their initial knowledge level. Feedback indicated that while the course was effective, instructors required more preparation time, and the second showing of instructional films provided substantial additional value despite suggestions to shorten the course. The report concludes that the training successfully provides a coherent framework for medical screening, combining symptom identification with procedural guidance. However, the authors recommend further research to evaluate whether the training increases appropriate medical referrals while minimizing inappropriate ones. They also propose refining the Medical Evaluation Checklist for daily operational use, suggesting it be condensed and approved by State Medical Advisory Boards to serve as a standardized communication tool between examiners and physicians. Additionally, the report includes a secondary curriculum component designed to help examiners detect false identification documents.
