This volume traces the history of accreditation of programmes in psychology, from the late 1940s to the turn of the century. In doing so, the book puts accreditation into focus, examining the challenges of coming to consensus with a variety of groups, each one having its own definition of excellence. This comprehensive work highlights the developmental stages of accreditation in psychology from its initiation to its current status, while also suggesting potential changes and challenges in its future. Accreditation experts analyse such topics as the development of accreditation activities in internship and post-graduate training. There is an emphasis in all of the chapters to define the influence of accreditation activities on the practitioner community and their reciprocal attempts to provide input to accreditation. Chapters are supplemented with personal accounts of accreditation as told by those who witnesses its dramatic development over time. The personal, political and archival information presented makes this a stimulating resource for those interested in the history of accreditation and psychology in general.
