Evaluators are becoming increasingly aware that, to provide maximum benefit to the programs they evaluate, they must address the systems within which the programs work. However, evaluation practice is often influenced by beliefs and assumptions that are rooted in an understanding of these systems as stable and predictable. We identify four traps…

Traditionally, evaluation has primarily tried to answer the question "Does a program, service, or policy work?" Recently, more attention is given to questions about variation in program effects and the mechanisms through which program effects occur. Addressing these kinds of questions requires moving beyond assessing average program…

Evaluation occurs within a specific context and is influenced by the economic, political, historical, and social forces that shape that context. The culture of evaluation is thus very much embedded in the culture of accountability that currently prevails in public sector institutions, policies, and program. As such, our understanding of the…

Sound evaluation planning requires numerous decisions about how constructs in a program theory will be translated into measures and instruments that produce evaluation data. This article, the first in a dialogue exchange, examines how decisions about measurement are (and should be) made, especially in the context of small-scale local program…

In recent years, increased focus on the effectiveness and accountability of prevention and intervention programs has led to greater government funding for the implementation and spread of evidence-based health and human service delivery models. In particular, attention has been paid to programs that require significant infrastructure investment…

This article presents the findings of a large scale study that tested a comprehensive model of predictors of three manifestations of sustainability: continuation, institutionalization, and duration. Based on the literature the predictors were arrayed in four groups: variables pertaining to the project, the auspice organization, the community, and…

In this paper we describe an evaluation training program sponsored by the Robert Wood Johnson Foundation and led by Duquesne University and OMG Center for Collaborative Learning designed to meet the challenge of developing a cadre of diverse evaluation professionals, specifically those from traditionally underrepresented or underserved…

In the present climate of public accountability, there is increasing demand to show "what works" and what return is gained for the public from investments to improve communities. This increasing demand for accountability is being met with growing confidence in the field of philanthropy during the past 10 years that the impact or effectiveness of…
