Need analysis - identifying and evaluating a group's expectations which have not but could be met - has become increasingly popular as a tool to inform decision makers. McKillip presents the primary social science research techniques used in need identification, such as client surveys and key informant interviews. He provides a framework for understanding and integrating this information in a need assessment. Emphasis is placed on convergent analysis and social marketing models of assessment. The book is designed for students, researchers and administrators in human services and education and includes examples from human service and education need analysis.
