The second phase of a two-phase study evaluated (through 24 care studies in California, Missouri, Illinois, and New York) the feasibility of implementing an evaluation model of workplace-based retraining programs developed during the first phase of the project in California. The feasibility study addressed two components of an evaluation system: (1) business selection and screening guidelines; and (2) performance assessment based on four types of performance outcome measures--company performance, work-unit performance, skill competencies, and wages and earnings. The study found the following: (1) the proposed evaluation system is consistent with widely recognized models of business training design and evaluation for training projects that are intended to improve business performance; (2) company performance indicators can be easily identified and measured in valid and reliable ways without imposing extra costs; (3) the seven screening guidelines can effectively address the most important targeting and substitution problems faced by state programs; and (4) the proposed evaluation system can be administered effectively without substantial costs being incurred by either the businesses or the program. The feasibility study concluded that state training grants are effective in expanding training opportunities and that an evaluation system can be implemented successfully. (Summaries of 24 case studies make up most of the document. They contain information on the following: training grant, focus of case study, overview of company, competitive problems, strategic and operational objectives, company performance measures, need for retraining, training program, need for state assistance, performance outcomes, training outcomes, and observations.)
