In light of the increasing interest in research on correctional officers, data are presented concerning the validity, reliability, and factor structure of the Klofas-Toch professional orientation inventory of correctional officer attitudes toward inmates. This 17-item instrument was administered to a heterogeneous sample of southern correctional officers and to a heterogeneous sample of probation/parole officers. The same four factor structure emerged in the correctional officer data as has been reported by Klofas and Toch (1982); however, separate analyses showed differential factor ordering and loading for black and white officers. The factor structure that emerged in the probation officer data differed from the structure found in the correctional officer data. Finally, the professional orientation inventory, while found to be a valid and reliable measure, did not explain much of the variance in correctional officer job burnout.
