With 1,155 state-operated adult correctional facilities housing more than 1 million people, there are a variety of approaches to oversight of state prisons.
Correctional oversight bodies generally fall into eight categories, according to a 2010 law review article by Michele Deitch, director of the Prison and Jail Innovation Lab at the University of Texas at Austin. They are governmental agencies or commissions, ombudspersons, inspectors general, legislative committees with inspection responsibilities, advocacy groups with formal right of access, citizens’ boards or advisory committees, general government auditing bodies, and protection and advocacy organizations with focus on prison issues.
