Dear Asira: Thank you for writing to us with your question. There are many places to learn about evaluation and evaluation models. Our own site, the Community Tool Box, might be helpful to you. There are plenty of materials on the site that you could review. Specifically, you could begin by looking at Chapter 36, Section 1 of the Tool Box, which is called ?A Framework for Program Evaluation?; this should give you a very good overview. Then you could look at the many other sections we have posted on Evaluation in Chapters 36, 38, and 39, about 15 in all. You can find these by clicking the ?Tools? menu tab on our home page, then ?Table of Contents.? Finally, you could also look at our Toolkits, including one on evaluation, which you can find by clicking the ?About the CTB? menu tab on our home page. All this should keep you busy for a while! If you are looking for more sites, one general site among many you could check is at www.wmich.edu/evalctr/checklists, which will lead you to summaries and checklists for a variety of evaluation approaches. In one sentence, though, we think the best way to evaluate any program is to carefully define its goals, to establish clear and measurable criteria for success, and then to evaluate based upon those criteria. Thank you for writing to us at the Community Tool Box; and all best wishes for success both in your training and in your career to follow.
