"Focusing on single-system designs, Evaluating Practice, 6/e presents clear guidelines on conceptualizing and measuring problems, developing practice-oriented evaluation designs, understanding and analyzing data, and ethical guidelines for practice evaluation. Unsurpassed among human service evaluation texts for bringing clarity to evaluation procedures, Evaluating Practice comes with a free CD-ROM featuring numerous programs, including the innovative SINGWIN program for analyzing data (created by Charles Auerbach, David Schnall, and Heidi Heft Laporte of Yeshiva University), and the CASS and CAAP programs (created by Walter Hudson) for managing cases and scoring scales."--Publisher's Website.
