Do magnet and charter schools exacerbate or ameliorate inequality?

School choice typically refers to opportunities to enroll youth in public and/or private educational alternatives to traditional neighborhood public schools. While these options continue to grow in the United States under the umbrella of school choice, magnet and charter schools are the most common forms of public school choice. In this article, we review the development of school choice and the differing historical and philosophical origins of magnet and charter schools. We then summarize what we know about the extent to which these public choice options exacerbate or ameliorate two forms of inequality-academic achievement and school segregation by race and class. Research suggests that magnet schools often encourage racial and class diversity, while charters contribute to racial and socioeconomic isolation. While low-income minority students may benefit academically from attending magnet schools, it is unclear whether charter schools have any effect on achievement when comparing charter school students to their counterparts in traditional public school. We expect that continued growth of magnet schools will likely promote school diversity both within and between districts, though some types of magnets may also inadvertently promote segregation. However, expansion of the charter school sector will heighten school segregation and exacerbate racial and socioeconomic isolation.
