Abstract: In this Ideas at Work series from Education Sector, Andrew Rotherham outlines five policy initiatives designed to reduce the tension between charter school advocates and critics and to encourage high-quality charter school growth. Specifically, they are: (1) lifting the limits on the number of charter schools in exchange for more rapid expansion of proven models; (2) trading high test scores from some charter schools for space for charter schools to operate; (3) linking transitional aid for public schools to access to facilities for charter schools; (4) tying increases in school funding to the expansion of high-quality charter schooling; and, (5) unionizing some charter schools with teachers' contracts that reflect charter schooling values.
