A major activity of any ESEA Title III project is evaluation. This paper suggests evaluation methods especially appropriate to such projects by applying a systems approach to the evaluation design. Evaluation as a system is divided into three subsystems: (1) baseline evaluation, which describes conditions as they exist before project treatment; (2) process evaluation, which provides information to aid decisionmaking in day-to-day operational activities; and (3) product evaluation, which measures the extent to which a set of project objectives has been met. These three evaluation methods provide information to facilitate decisionmaking during the course of the project, instead of postponing evaluation until after completion of the project. This type of continuous evaluation system should be an important part of any innovation program. (Figure 4 on page 30 may reproduce poorly because of marginal legibility.) (RA)
