AI offer first-hand account of a key stage in the development of parental choice in American public schooling, when Massachusetts state officials, concerned not to repeat the trauma and disruption resulting from mandatory reassignment of students to achieve desegregation in Boston, persuaded and helped more than a dozen other cities to adopt plans based upon guided parental choice. By 1993 over 200,000 students (25% of the state's public school enrollment) were attending schools in communities relying on parental choice to address the isolation of minority students; most of these had abandoned residence-based assignments altogether. This account describes the means by which this was achieved. This essay does not discuss charter schools, vouchers, tuition tax credits, faith-based schools or educational savings accounts; those came in the future. It is reasonable to believe, however, that the widespread and successful adoption of parental choice of local public schools in Massachusetts helped to prepare the way for such further developments nationwide.
