Charter schools also use a variety of techniques to control which students they will choose to serve. They can establish bureaucratic obstacles that filter out families that lack the resources to jump such hurdles. They can limit their applicants by limiting their services in areas such as special education. Robert Pondiscio’s 2019 book How The Other Half Learns details how New York’s Success Academy filters out families that don’t meet their preferred profile. A demanding application process, repeated meetings that lay out the demands of the charter, measuring sessions for school uniforms, and pre-school orientation meetings all help Success Academy filter out the parents who are unable or unwilling to meet their requirements For charter schools, student success is a critical piece of marketing; also, in some cases, their program is only geared toward a specific sector of students.
