A Simplified Procedure for Identification of Optimal Test Score Cut-Off Points for Non-Rated Submariner Candidates.

摘要

The goals of this study were to identify the most effective cut-off points on the distributions of selected Basic Test Battery (BTB) score combinations obtained from a sample of non-rated volunteers for Basic Submarine School. Based on the disparities in the cumulative percentage BTB score distributions obtained from 955 non-rated submariner candidates, optimal ECOP's (Experimental Cut-Off Points) were delineated for GCT, GCT+MECH, GCT+MECH+SP, ARI+MECH+SP (Shop Practices), and for SP test alone. Capable of being applied by a middle-level clerk, the analytical techniques provided estimates of the maximum COPV (Coefficient of Practical Validity), an index of selection efficiency, as well as an estimate of the False Positive (FP) and false megative losses for several ECOP's for each test score or score combination.
