A growing body of research suggests that school management models emphasizing teacher influence in school governance have a range of benefits, including increased teacher job satisfaction, more-effective organizational learning, and improved academic performance. However, research also suggests that teachers and principals have different views of teacher influence in schools, with principals perceiving higher levels of teacher empowerment than teachers themselves. Much of this research has been based on local or regional samples--not a nationally representative group of educators. Data from the RAND Corporation's web-based American Educator Panel (AEP) surveys provide greater insight into teacher and principal perceptions of teacher influence in school decisionmaking. The AEP asked a nationally representative sample of teachers and principals to rate the extent to which they agree with the following statements: (1) Teachers are involved in making important decisions at my school; (2) Teachers have a lot of informal opportunity to influence what happens at my school; and (3) Teachers feel comfortable voicing their concerns.
