Teacher preparation programs are required by the National Council for Accreditation of Teacher Education (NCATE) to assess the knowledge, skills, and dispositions of teacher candidates. Dispositions and the personal values that support them are defined differently by NCATE and other experts in the fields of education and business. In order to better understand dispositions the researchers examined the relationships between the personal values and dispositions of teacher candidates and successful teachers. Using the Rokeach Value Scale, results showed significant relationships between values and dispositions for teacher candidates and successful teachers. (Contains 13 tables.)
