California's Three-Tier Driving-Centered Assessment System Process. Analysis

摘要

On September 14, 2006, California Governor Arnold Schwarzenegger signed Assembly Bill 2542 (Daucher) into law, adding Section 1659.9 to the California Vehicle Code, and calling for a pilot study by the California Department of Motor Vehicles (CA DMV) of the 3-Tier Assessment System. This manuscript (the process report) constitutes the first of two reports on the 3-Tier Assessment System. It details the planning and implementation of the pilot, the process outcomes for the 12,346 CA DMV customers who participated in the pilot as well as the 4,853 customers who constituted a baseline comparison group, and the results of the subsequent multi-component process evaluation. The process evaluation includes a description of the costs to implement the pilot, discussion of various threats to the methodological validity of the process and outcome analyses, and an estimation of the potential costs of statewide implementation. An appendix to this report (published separately) contains more detailed analyses associated with four components of the process evaluation: the results of a survey of participating staff, the results of qualitative interviews conducted with participating staff, the results of a survey of pilot customers, and the results of an analysis of customer outcomes on the Pelli-Robson contrast sensitivity assessment.
