A Comparison of Expert Ratings of Task Difficulty with an Independent Criterion
Abstract
This report evaluates the possibility of utilizing 'expert' ratings of task difficulty as a substitute for actual measurement or determination of task difficulty. Task difficulty information exists for only a small number of tasks in the US Army inventory of tasks. Accurate ratings of task difficulty would reduce the logistical problem of actually measuring difficulty for each task in the inventory. Expert ratings of task difficulty were compared with the results of a criterion-referenced test of the same tasks. There was a non- significant correlation between the expert ratings and the independent measure of difficulty. There is a need for further research into methods of improving expert ratings of task difficulty.
