People who are impacted by the criminal justice system ("system-impacted") face barriers when seeking financial aid to pay for college. Between the late 1960s and the early 2000s, Congress created laws that prohibited incarcerated students and students with certain criminal convictions from receiving federal grants and loans. This paper offers a comprehensive review of the history of those laws, which provides context for current debates on restoring Pell Grants to students in prison. Legislative documents, scholarly sources, and news reports were studied to build this historical review. Key lessons from history are discussed as to how Congress might treat system-impacted students in the near future.
