Criterion referenced test methodology is used in this study for determining the extent of overtraining and undertraining through the use of the minimally acceptable performance level (MAPL), as proposed by Nedelsky (1954). A MAPL was computed for each area on a 320-item, 12-area test. The raw area scores of the technicians were transformed to standardized area criterion scores. An analysis of variance was performed using a fixed effects model with paygrade categories nested under each area. The null hypothesis was rejected at the .005 level of significance. A post-hoc multiple comparison (Newman-Keuls) was used to determine which areas indicated the possibilities of overtraining or undertraining. The results were verified by subject matter experts.
