The Air Force correctional staff works to prepare inmates for a return to civilian life since only a few eligible inmates volunteer and are accepted for a return to active duty. The 3320th supervises male and female inmates in a wide range of custody grades in an environment that adheres to high military standards. Traditional and modern management models are combined into a modified case management system. The program at Lowry uses some elements of the boot camp philosophy in terms of dress and conduct. Most inmates have constructive job assignments outside the corrections complex which provide essential support services on the base. Within the first 30 days of incarceration, inmates are evaluated and begin a rehabilitation program including physical training, religious guidance, and classes on substance abuse and stress management. The staff use a cognitive-behavioral model to identify and confront inmates' problems and to give them the opportunity to modify their thinking patterns and behaviors. Inmates in the substance abuse and sex offender programs are required to develop their own relapse prevention programs.
