Social Theory,Social Programs,and Program Evaluation: a Metatheoretical Note*

Program evaluation attempts to assess the consequence of deliberate efforts to intervene in ongoing social processes. Efforts to understand and explain social processes and social change constitute social theory. The evaluation of social programs provides an opportunity both to test existing theories of social change and to discover new theory. Current notions about theory in the evaluation literature are reviewed and cues from that literature provide the basis for suggested directions in the relationship between the design of programs, their evaluation, and theory.
