From a psychometric standpoint, we examined performance of an intellectual developmental disorder sample, and scores falling within seven relevant standard score ranges were compared to the percent predicted from the normal curve. Based on the normal curve, approximately 2.7% of the normal distribution would obtain a score less than or equal to a standard score of 69; however, on average, more than 76% of this sample scored within that range across all AAB subtests and composites.
