Key legislative objectives of charter schools are to provide more school and classroom options, increase teacher influence over decision making, and increase school autonomy from state and district policy. Using national data from the 2003-4 School and Staffing Survey, we found that charter schools attained these legislative objectives when compared with regular schools, although increases in teacher influence and school autonomy were modest. Although charter schools have been implemented much as intended by legislation, other research has shown that charter schools in general have not improved student achievement--a major objective of charter school legislation.Our results suggest that this cannot be attributed to a failure to implement the charter school concept with respect to the legislative objectives examined.
