The goal of this paper is to be helpful to small agencies and not-for-profit organizations as they address the issues of program evaluation. Today almost anyone affiliated with a program or intervention -of nearly any kind-is likely to find themselves dealing with the issue of evaluation. No doubt many program leaders are anxious to document their program’s effectiveness; for others, tightening budgets may drive efforts to assure continued support from funders and fund raisers. And, who is not tempted by the spreadsheet on their computer. "Data" sounds and feels easy, so why not do so? Then, of course the call for evaluation is fueled by the constant barrage of "evidence-based" or "best practice" programs that get called-for and, occasionally, cited in the journals, newsletters and, now, webinars. Finally, it is easy to be drawn in by the sophisticated and complicated evaluations that get covered in a minute or two on NPR or the evening news. The siren call of evaluation is difficult to ignore.
