The primary purpose of this study was to determine the legal knowledge of Pennsylvania superintendents regarding summative teacher evaluation and to determine whether their knowledge level was adequate. Pennsylvania was selected for this state-wide study of superintendent's legal knowledge of teacher evaluation for two reasons. First, Pennsylvania is one of the leading states in terms of its litigation and has a representative set of legislation and regulations (Zirkel, 1996). Second, Mata (1998) constructed and validated a teacher evaluation instrument specific to Pennsylvania statues and relevant case law. The secondary purpose was to ascertain whether superintendents' knowledge level was significantly different in terms of their years of experience. Based on the findings from this study, superintendents would benefit from ongoing legal training specific to teacher evaluation law. (Contains 1 table.)
