This report was designed to validate a method for evaluating the difficulty levels of Air Force enlisted jobs. Multiple regression equations which captured the job difficulty evaluation policy of supervisors in two electronics and two general career ladders were produced. The equations yielded predicted difficulty values for 250 jobs from each career ladder. These values correlated above .81 with supervisory rankings of job difficulty validating the findings of previous job difficulty studies conducted in 12 Air Force career ladders. Various constant standard weight equations were developed and compared. Of these, an equation derived from all 16 career ladders offered valid predictions when it was applied in the electronics area. Although this 16-ladder equation showed no significant improvement over the 12-ladder equation, it has wider applicability than the 12-ladder equation currently in use. The 16-ladder equation is recommended as a replacement because it is based upon results from all four aptitude areas and because it has been successfully applied in career ladders with both high and low aptitude entrance requirements.
