SCHOOL choice poses a fundamental challenge to the age- old concept of neighborhood schools. So, unsurprisingly, it has been surrounded by intense controversy. Despite this, school choice is spreading. Back in 1987, Minnesota became the first state to approve school choice. Less than a decade later, over half the states had considered, many of them adopting, some school-choice reform. In a handful of cities—New York, Cambridge, Massachusetts, Montclair, New Jersey—school-choice reforms have been in existence for much longer. Many others-Cleveland, Indianapolis, and Milwaukee—have recently followed their lead.
