Proponents of the charter school movement often claim that the decentralized, autonomous nature of charter schools from district and state authority allows teachers greater influence over school policy both instructionally and administratively. Using a data set of 1,427 New York City schools, we empirically examine the extent to which organizational characteristics predict the amount of policy influence charter schools and traditional public schools grant to teachers. Results indicate not only do charter schools grant their teachers less policy influence but also other organizational features are stronger predictors of teacher policy influence including several nonlinear relationships. Directions for future research are discussed.
