ABSTRACT
ImPACT® Pediatric is an examiner-administered iOS-based battery of neuropsychological tests designed to measure neurocognitive functioning in children ages 5–11. This study documented Multivariate Base Rates (prevalence of low scores when multiple test scores are considered simultaneously) in the ImPACT® Pediatric standardization sample (N = 892). In the total sample, it was common for children to obtain at least one low factor score using the 25th percentile [T 43; base rate (BR) = 54.2%], 16th percentile (T40, BR = 38.1%), and the 10th percentile (T37, BR = 31.1%). However, it was uncommon for children to obtain two (or more) low factor scores using any of the above-listed cutoff score.
