Abstract
This article examines the issues of title usage, area of competence, and the boundaries of appropriate practice for professionals in applied sport psychology trained in either psychology or sport science programs. Considerable discussion is focused on the legal and ethical ramifications of the title of sport psychologist and who may and may not use it. Emphasis is also placed on defining and clarifying area of competence as it pertains to the two educational backgrounds. Drawing upon previous writing in the area and literature from outside sport psychology, guidelines are offered for determining whether professionals are performing within their area of competence based upon their education, training, and experience in three domains: presenting problem, intervention skills, and client population.
