Currently a sound and reliable measure of a student-athlete's career development does not exist. The purpose of this study was to develop a psychometrically sound instrument that measures the career situation of student athletes. Participants for the study were 204 (138 male and 66 female) student-athletes from a large midwestern Division I university. A primary axis factor analysis using promax rotation revealed that five factors, named: Career Development Self-efficacy, Career versus Sport Identity, Locus of Control, Barriers to Career Development, and Sport to Work Relationship, accounted for 81.39% of the common variance in the data. The internal reliability of each factor of the Student-Athlete Career Situation Inventory (SACSI) was established using Cronbach's alpha (0.70 to 0.80). The criterion validity of the SACSI was investigated by regressing career experiences and gains on the five factors of the SACSI, resulting in significant squared multiple correlations (0.17, 0.28).
