The purpose of this study was to determine the extent to which cooperating agricultural education teachers used selected supervision models. The relationships between maturity characteristics of the cooperating teachers and their choices of a supervision model were also examined. Results showed that cooperating teachers commonly used clinical, contextual, and conceptual supervision models. They also commonly used nondirective and directive informational styles from the developmental supervision model. Maturity of the cooperating teachers was not related to their choices of structured or unstructured models of supervision. Future studies should examine the relationship between cooperating teachers' use of supervision models and contextual factors like teaching load and administrative responsibilities. The importance of student teacher characteristics as factors in cooperating teachers' choices of supervision models should also be examined. (Contains 4 tables.)
