School choice refers to education options that allow students and families to select alternatives to public schools. It is a term that represents the many ways students access their K–12 education, including public schools, private schools, charter schools, home schools, or any other learning environment families choose. School choice allows public education funds to follow students to the schools or services that best fit their needs. The idea behind school choice is to give all parents the ability to choose whichever school or learning environment best meets their child’s needs, regardless of whether its public or private. School choice mechanisms are algorithms that aim to match pupils to schools in a way that respects both the pupils preferences and the schools priorities. The most common school-choice mechanisms are variants of the deferred-acceptance algorithm and random serial dictatorship. The main concern in designing a school-choice mechanism is that it should be strategy-proof for the pupils so that they reveal their true preferences for schools. School choice is a subject of fierce debate in various state legislatures across the United States.
