The Wechsler Preschool and Primary Scale of Intelligence, 3rd ed. (WPPSI™-III) is an intelligence test used nationally for children from 2 years 6 months (2:6) to 7 years 3 months (7:3) of age. A licensed psychologist administers the test, which is used as part of a neuro-psychological evaluation. The test is also used for private school and public Gifted and Talented program admissions in certain parts of the country. The WPPSI™-III contains 14 subtests, though the specific subtests administered during the test vary based on the child's age as well as which part of the country and for what reason the test is taken.
Aristotle Circle currently offers products for 9 of the 14 WPPSI™-III subtests and is developing material for the remaining 5 subtests.
