This report examines interrater reliability estimates for task difficulty raters having differing levels of familiarity with rated tasks. Data were collected from 455 NCO supervisors who rated the difficulty and familiarity of 424 tasks in the Aircraft Electrical Repair career ladder task inventory. The results showed that the interrater reliability estimates R sub KK decreased from .930 to .802 for six task difficulty rating scale conditions in which ratings were eliminated due to levels of familiarity. This finding suggests that little is to be gained from eliminating task difficulty ratings based upon an experienced judges level of familiarity with tasks. Author
