banding

banding

n. an approach to setting cutoff scores in personnel selection. Several ranges of scores known as score bands are identified, usually on the basis of the standard error of measurement for the test or predictor variable. Rather than being considered individually, all candidates who score within the same band are considered equally qualified. Consequently, hiring decisions are made from within band ranges, in contrast to traditional approaches that choose the highest scorer first, the next highest scorer second, and so forth.
