This article outlines the development and implementation of a cost-effective approach to client and program evaluation. The indices presented summarize a client's acquisition of behavioral skills (Skill Acquisition Index) and progression along a continuum of becoming less dependent and more productive (Client Movement Index). Data are presented summarizing how the two non-monetary outcome measures have been used in formative program evaluation. The paper also discusses some of the problems involved in implementing cost-effective analyses in rehabilitation programs and suggests specific strategies to overcome the problems.
