Abstract: California school districts are withholding as much as 37 percent of the funding for special education students attending charter schools. As a result, the majority of California charter school directors surveyed in this study say they are not satisfied with the special education arrangements between their charter schools and school districts. The study makes several recommendations to boost the performance of special education programs in charter schools, including: 1) let special education funding follow the child; 2) use special education cooperatives and insurance; 3) employ value-added testing; and 4) connect explicit financial incentives directly to student performance.
