School-to-prison pipeline
In the United States, the school-to-prison pipeline (SPP), also known as the school-to-prison link, school–prison nexus, or schoolhouse-to-jailhouse track, is the disproportionate tendency of minors and young adults from disadvantaged backgrounds to become incarcerated because of increasingly harsh school and municipal policies. Additionally, this is due to educational inequality in the United States.
