To examine programs currently in place, an evaluation model was designed to insure inclusion of all those who have a stake in program performance. The evaluation design includes: (1) a set of researchable questions which are to be answered by the evaluation, each question referenced to one or more appropriate audiences; (2) for each question, the items, measures, and data sources to be used, with empirical estimates of quality for each item-source combination; (3) the collection procedure (instruments and user guides) to be employed for each item, and a schedule for collection; (4) a sampling plan for all samples to be used in the evaluation; (5) an analytical plan, to include data maintenance and quality control, aggregation rules (for items, constructs, program components), and statistical treatment; (6) a reporting plan, tailored to the needs of each audience; and (7) a complete management and staffing plan to implement the evaluation design. The implementation of this evaluation model is discussed in the framework of field studies of programs in place, an evaluation of the needs of users, technical limitations on the design, and the formulation of the design.
