This book is a must-have for any clinician or academician who supervises trainees at any level of training. Because of its workbook format, it is efficient to use as either a practical resource or as a textbook, and it lends itself well to a multi-disciplinary environment. Psychiatrists, Psychologists, Counselors, Social Workers, Teachers, etc. - all will find the workbook equally useful. It has a developmental perspective, and integrates theory, current research, and practice with useful and practical tools for becoming an effective supervisor. In comparison with other available resources on Supervision, I rate this workbook as more thorough in content, and more practically useful than any supervision resource in my library.
