This paper from the Heritage Foundation summarizes the best research on the impact of school choice programs. The conclusion?
A growing body of empirical evidence demonstrates the many positive benefits of providing choice in education. Instead of policies to increase spending on the public education system, states and local school districts would better serve students by empowering parents with control over their share of education funding.
I wanted to publicly say how much I appreciate Georgia Public Policy Foundation. For those of you that will be entering the Legislature or are relatively new you may not quite yet appreciate how much we rely on Georgia Public Policy Foundation’s research and work. As you know we’re a citizen’s legislature. We have very little staff. They have been an invaluable, invaluable resource to us. To put this [Forum] on and the regular programs that they do throughout the year make us better at what we do. (At the 2012 Georgia Legislative Policy Forum.)
