Abstract
The present study compared two instruments for assessing competency to stand trial, The Competency Screening Test and a revised version of The Georgia Court Competency Test. in a sample of 140 defendants admitted to the forensic unit of a state hospital for court-ordered pretrial evaluation. Scores on the tests were used to predict staff decisions about competency. Correlates of scores on the two tests also were examined. The tests were highly correlated with one another and with the decisions of forensic examiners. Although neither of these instruments should provide the sole basis for competency decisions, both may be useful components of a comprehensive program of competency evaluation.
