The GAO (Government Accounting Office) has a long and respected history of evaluation. Many luminaries at AEA (American Evaluation Association) have spent/are spending their professional careers at GAO. The GAO has just published (January 2012) their handbook on evaluation. It is called, DESIGNING EVALUATIONS 2012 Revision. Nancy Kingsbury, a longtime AEA luminary, wrote the preface. For those of us who receive Federal money in any form (grants, contracts, Extension) this will be a worthwhile read. Fortunately, it is a relatively short read (text is 61 pages plus another 7 pages of appended material). This manuscript explains the “official” federal view of evaluation. It is always good to know what is expected. I highly recommend this read. The worst it could be is good bedtime reading…zzzzzz-zz-z.
