Each composite index combines to form the Full Scale Intelligence Quotient which measures overall intellectual ability. It consists of two batteries, the Early Years Battery and the School-Age Battery, which were normed for overlapping age ranges to increase the usefulness for children of varying ability levels. These cluster scores consist of six core subtests (or four, for children 2:6-3:5) that are designed to measure verbal, nonverbal, and spatial reasoning.
