Case management (CM) is a client-level approach to treatment that promotes the integration of human services across service providers. This approach has been adopted for home health care–based services through the case manager role. Few studies have explored the nonclinical competencies needed for case managers to be effective in their roles. This research documents the design and validation of a nonclinical competency model for case managers. Five competencies were identified: systems thinking, personal and professional accountability, facilitating creative thinking, communicating, and building relationships. Behavioral statements for each competency were assessed by a sample of case managers (for clarity, frequency of use, and experience needed) and generally supportive of the model structure. Implications for competency-based research and practice in CM are discussed.
