In a conversation with a colleague on the need for IRB when what was being conducted was evaluation not research, I was struck by two things:
Leaving number 1 for another time, number 2 is the topic of the day.
A while back, AEA 365 did a post on the difference between evaluation and research (some of which is included below) from a graduate students perspective. Perhaps providing other resources would be valuable.
To have evaluation grouped with research is at worst a travesty; at best unfair. Yes, evaluation uses research tools and techniques. Yes, evaluation contributes to a larger body of knowledge (and in that sense seeks truth, albeit contextual). Yes, evaluation needs to have institutional review board documentation. So in many cases, people could be justified in saying evaluation and research are the same.
Carol Weiss (1927-2013, she died in January) has written extensively on this difference and makes the distinction clearly. Weiss’s first edition of Evaluation Research was published in 1972.She revised this volume in 1998 and issued it under the title of Evaluation. (Both have subtitles.)
She says that evaluation applies social science research methods and makes the case that it is intent of the study which makes the difference between evaluation and research. She lists the following differences (pp 15 – 17, 2nd ed.):
(For those of you who are still skeptical, she also lists similarities.) Understanding and knowing the difference between evaluation and research matters. I recommend her books.
Gisele Tchamba who wrote the AEA365 post says the following:
She also sites a Trochim definition that is worth keeping in mind as it captures the various unique qualities of evaluation. Carol Weiss mentioned them all in her list (above):
