The Descriptions of Specialty Practice is a document developed for the orthopaedic specialty area that outline the knowledge, skills, and abilities related to clinical practice in the orthopaedic physical therapy. The DSP content is based on a detailed practice analysis conducted by the orthopaedic specialty council. A practice analysis involves extensive research, including survey data and judgments of subject matter experts, of the knowledge, tasks, and roles that describe advanced specialty practice. The orthopaedic specialty council develops the OCS exam from the DSP and includes a percentage of questions from each of the major content areas identified in the practice analysis.
