In general education, researchers find candidates' pre-service experiences are a tool for socialization into the knowledge, norms, and values of the profession. An important aspect of this process is program vision--the collective understanding of teaching put forth by a preparation program. Yet, few investigations in special education examine program vision. Using interviews with candidates across six teacher preparation programs, the author generates theory to understand the role of vision in special education teacher candidates' professional socialization and how experiences of program vision are associated with their conceptions of their future roles and responsibilities. Candidates' conception of special educators' roles reflected three characterizations consistent within, but distinct across programs: Direct Instructor, Supportive Differentiator, and General Responder. Each profile was associated with unique roles and responsibilities for special educators. Findings draw attention to the importance of examining vision as a tool for professional socialization in special education teacher preparation.
