This assessment includes criminal and institutional violence history, program needs, and supervision requirements. These levels dictate the degree to which an inmate's movements are restricted. Minimum and medium each contain two levels of custody. Minimum indicates the lowest risk and the least restriction on movement. Medium is a step up in risk and restriction.
Close custody represents higher risk and more restriction in movement.
Maximum is the highest risk classification and the greatest restriction. No, they do not. Inmates may only correspond by regular mail and collect phone calls. The average age of offenders in Montana prisons is 36 years old. In 1991 the average age was 34 for males and 33 for females.
