In 2017, Matthew Chingos and Kristin Blagg of the Urban Institute convened a group of researchers to analyze students' school choices and travel to school in five cities-- Denver, Detroit, New Orleans, New York, and Washington, D.C.--where families are able to select from among many charter and district schools. The team found that a large number of students in these cities take advantage of school choice, and that it often provides them with important academic benefits. Traveling for these benefits, however, does come with some costs to students and their cities' education systems and at times reveals conditions of unequal access. Cities are hungry for innovative solutions to the transportation challenge. The five cities they examined have adopted a number of different policies for providing transportation for students who opt out of their neighborhood school. In New Orleans, New York, and D.C., students who choose another school can still receive district-provided transportation. In D.C., all students, regardless of their distance from the school, receive free transportation to school on public-school buses or via free access to public transit. In New Orleans and New York, transportation support depends on how far away students live. In Denver, students who exercise choice and live and enroll in any school in specific transportation zones served by Success Express, a dedicated shuttle-bus service, receive free transportation. In addition, most charter schools offer public school-bus transportation to students. In Detroit, students who select a different district school or a charter school are not guaranteed transportation, but some charter schools do offer it.
