The primary purpose of this monograph is to describe how learning curves can be applied to vocational evaluation procedures to enhance the reliability and accuracy of performance prediction. Particular emphasis is placed on describing two techniques known as the "best 20 percent method" and the "Performance Analyzer and…

A study was conducted (1) to obtain an estimate of the amount of error in prediction that occurs when static measures are used to interpret work-sample performance; (2) to identify a number of dynamic performance measures that reflect learning that might occur on the task; and (3) to compare the predictive accuracy of those measures to that of…
