This report, for the first time ever, provides a state-by-state breakdown of the key elements a policymaker needs in order to understand the legal environment for school choice in any given state--and to craft appropriate legislation to expand educational opportunity. This guide is intended to arm policymakers and advocates with the essential background needed to craft constitutional school choice legislation--and to forge ahead with confidence in delivering equal educational opportunity to all families, regardless of their means. But the analysis and recommendations in this report are very general and should be just the beginning of one's effort to understand school choice and one's state constitution. A glossary is included. Individual sections contain footnotes.
