Thomas Jefferson recognized the value of reason and scientific experimentation in the eighteenth century. This chapter extends the idea in contemporary ways to standards that may be used to judge the ethical propriety of randomized trials and the dependability of evidence on effects of social interventions.

The advances discussed are: (1) facilitating advances that consist of changes that make carrying out quantitative evaluation easier; (2) advances in measurement; and (3) advances in…

This eight chapters of this special issue introduce the use of a template to specify program components as a new tool for program evaluation. The template articulates the components needed for program delivery and provides a systematic method for assessing program implementation. (SLD)

This article describes two areas of differences: (1) the framework for doing SNA; and (2) data collection, analysis, and specific measures. SNA is about relationships and how to…

The seven articles of this special issue focus on theory and research related to survey methods and whether evaluators need information that is absent from the larger survey literature. These articles reflect the view that the considerations relating to good survey research apply also to using surveys in evaluation. (SLD)
