Discussion:
Evaluation research is a unique, applicable form of scientific inquiry. While the conceptualizations of ordinary research methods form the foundation upon which evaluation research rests, there are some nuances found in evaluation that are unique. One such nuance centers on questions of whether a particular policy or program can be evaluated.
Critique the design of an evaluation by describing what evaluability means and why proper evaluability is so fundamental to the success of any specific project. For examples on strategies for how to determine evaluability, you should make use of the Lipsey, Petrie, Weisburd, and Gottfredson article and required reading from the Rossi, Lipsey, and Freeman text. You may support your position with both scholarly and non-scholarly credible sources.
