Choosing an evaluation strategy.

Abstract

Most people making their first attempt at program evaluation will ask the same general kinds of questions at the outset of their endeavor: Why evaluate? How much will it cost? Can I do it myself, or will consultants be required? How scientifically rigorous must it be? Should I have a control group? How big should the sample be? etc. All of these questions can be answered, but only after a set of important assumptions about the program being evaluated has been carefully specified. In most cases, all of these questions can be answered quite adequately by the person(s) asking them. Very little technical expertise is required. In this article we present an approach to the formulation of a general evaluation strategy, including a method for answering some of the questions that need to be answered first.
