A Validation and Comparative Evaluation of Four Predictive Devices for Classifying Federal Probation Caseloads — A Report to the Committee of the Judicial Conference of the United States on the Administration of the Probation System

James B. Eaglin, Patricia A. Lombard
January 1, 1982

An evaluation of the comparative validity of four risk prediction scales used for classifying federal probation caseloads. The authors found the U.S.D.C. 75 Scale to have the best balance of validity and predictive power, and they recommend that it be used by all U.S. probation officers. (The U.S.D.C. 75 Scale was subsequently modified and renamed the Risk Prediction Scale 80 and is now undergoing modification again. It is in use in all federal probation offices.)
