This study examined the factor structure of the School Counselor Leadership Survey (SCLS). Survey development was a threefold process that resulted in a 39-item survey of 801 school counselors and school counselor supervisors. The exploratory factor analysis indicated a five-factor structure that revealed five key dimensions of school counselor leadership: (a) interpersonal influence, (b) systemic collaboration, (c) resourceful problem solving, (d) professional efficacy, and (e) social justice advocacy. This article discusses implications for practice, research, and training.
