The Wechsler Preschool and Primary Scale of Intelligence, Third Edition (WPPSI-III)

Provides: • An overall estimate of general intellectual functioning (FSIQ), as well as separate indices of verbal ability (VIQ) and nonverbal reasoning and problem solving (PIQ). Additional indices can be calculated by administering additional subtests in order to obtain an estimate of processing speed (PSQ) and a general language composite (GLQ). The test now includes two levels, representing formats for children ages 2-06 to 3-11, and another for ages 4-00 to 7-03.
