This report is intended to assist those agencies considering using California's Corrections 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 interpretation of cutoff scores in general, cutoff scores for the Corrections Officer Examination, setting an operational cutoff score, and using scores to augment entry-level selection decisions.
