The guru-driven nature of sport psychology has contaminated the field and how it is perceived, evaluated, and valuated by coaches, athletes, and decision makers in organizations who may want to utilize the services of sport psychology practitioners. This chapter provides a foundational and fundamental rationale for advancing evidence-based and validated athlete assessment and intervention protocols. The prevalent approach to applied sport psychology is practitioner-centered. The American Board of Sport Psychology (ABSP) mission is to advance practice, education, and training standards in the field of applied sport psychology as well as provide licensed psychologists the opportunity to achieve board certification in sport psychology. Sport psychologists and sport psychology practitioners must distinguish themselves from coaches and other practitioner-advisors who work with athletes. Sport psychology offers practitioners of highly disparate education, training, experience, and credentials an unparalleled opportunity to break into the elite strata of sports.
