This report is intended to assist those agencies considering using California's Probation Officer Examination as a tool for selecting personnel. It is intended to provide agencies with guidance in setting test cutoff scores rather than an exhaustive discussion of all of the factors that must be considered before setting cutoff scores for actual operational use. The following topics are discussed: the nature and purpose of cutoff scores in general, facts about the development of the Probation Officer Examination that must be considered when selecting a cutoff score for it, factors that influence and are influenced by the choice of a cutoff score, and the recommended method for setting cutoff scores and using the Probation Officer Examination to augment entry-level selection decisions.
