Program evaluation: large-scale and small-scale studies

This booklet is about small-scale and large-scale program evaluation studies. In many cases, both small- and large-scale studies are needed within any one evaluation project. In this booklet the authors argue that there is a need for both kinds of studies – provided that they are conducted according to scientific standards. Throughout the booklet, an emphasis has been placed on basic concepts and principles and generally accepted best practices. The booklet is organized around seven principles of sound program evaluation. A bibliography of pertinent publications has been included at the end of the booklet.
