A cross validation of findings relative to the value of a fair test concept is presented. The concept is based on the conjecture that persons who demonstrate the ability to learn a sample of the tasks of a job will--given appropriate on-the-job training--be able to achieve an absolute proficiency criterion of job success. An initial validation conducted after the sample had nine months job experience had provided support for this contention. The cross validation conducted after the sample had 18 months of job experience similarly supported the contention. However, as anticipated, attenuation of predictive power was demonstrated in the 18-month cross validational followup. For the nine-month followup, the concept yielded discriminant functions which provided 74 correct classification. For the 18-month followup, 62 correct classification was demonstrated. Author
