The Center for Public Education has been examining the research and data related to school choice in hopes of informing the conversation about effective policies. This report turns from looking at the impact of school choice to examining access to options within the public education system. It first estimates how many students are able to choose which public school to attend, regardless of whether or not they take advantage of the opportunity. Using data from the federal Schools and Staffing Survey, it then documents the prevalence of various program choices inside public schools and, where possible, compares these to private schools. It concludes with a discussion of growing efforts by public schools to personalize learning, which show a lot of promise for aligning students' different interests and needs with effective pathways toward success.
