The purpose of this collection was to measure the extent to which the Prisoner Management Classification (PMC) system in Washington state improved overall operations of prison facilities and reduced safety risks to inmates and staff. Four primary issues were addressed: (1) To what extent the PMC reduces rates of assaults on staff and inmates, (2) To what extent the PMC reduces rates of other serious misconduct, (3) To what extent the PMC increases rates of inmate participation in work or vocational programs, and (4) To what extent the PMC enhances staff job satisfaction, morale, and staff performance. Information is included on outcome variables against which comparisons between the experimental and control groups can be made. For each correctional facility, figures were collected for the number of staff-inmate assaults, number of inmate-inmate assaults, number of suicides and suicide attempts, number of escapes and escape attempts, number of "serious" disciplinary incidents, number of total staff, number of inmates, number of security staff vacancies, rated capacity of the facility, number of staff transfers and reasons, and number of inmates involved in educational, vocational, and work programs. Demographic variables include date of birth, sex, and race. Additional information concerns the family structure of the inmates and conditions surrounding the inmates' lives prior to entering prison.
