Transportation, or the lack thereof, can be a huge barrier to families exercising choice. Simply because a state authorizes the creation of charter schools or grants vouchers to families looking to send their children to private schools doesn't mean that those children will actually be able to attend those schools. They have to be able to get there safely, on time, and ideally after spending as little time on the bus as possible. Policies vary from state to state, district to district, and school sector to school sector. Whether or not students are provided with transportation can vary based on their proximity to their school, their age, the type of school they attend, the existing public transportation infrastructure in the city in which they live, and other factors. Policy plays a role as well. In some locations, laws provide guarantees for students that they will have free transportation to the school of their choice. In others, students are on their own. In this report, the authors combed the statutes and regulations in all 50 states to determine exactly how each handles the transportation of K-12 students to schools of choice, often via inter-district public school choice, charter school choice and private school choice. McShane and Shaw summarize statutes and identify some limitations and challenges that states face as school choice options continue to grow and families continue to need and expect transportation solutions.
