For people younger than 16, the Wechsler Preschool and Primary Scale of Intelligence (WPPSI, 2½–7 years, 7 months) and the Wechsler Intelligence Scale for Children (WISC, 6–16 years) are used. [14] Intelligence tests may be used to assess the level of cognitive functioning in individuals with psychiatric illness or brain injury.
The test is currently in its second edition, published in 2015. [2]Both editions are suitable for evaluation of intellectual giftedness, [3] and high scores are accepted as qualifying evidence for high IQ societies such as Intertel (min. IQ ≥ 135) and American Mensa (min. IQ ≥ 130).
There is some overlap between tests: children aged 6 years 0 months through 7 years 7 months can complete the WPPSI or the WISC; children aged 16 can complete the WISC-V or the WAIS-IV. Different floor effect and ceiling effect can be achieved using the different tests, allowing for a greater understanding of the child's abilities or deficits ...

[1] It was revised in 1989, again in 2001, and most recently in 2014; this last version is commonly referred to as the WJ IV. [2]
One hindrance to widespread understanding of the test is its use of a variety of different measures. In an effort to simplify the information gained from the Binet–Simon test into a more comprehensible and easier to understand form, German psychologist William Stern created the well known Intelligence Quotient (IQ).
The CogAT is one of several tests used in the United States to help teachers or other school staff make student placement decisions for gifted education programs, and is accepted for admission to Intertel, a high IQ society for those who score at or above the 99th percentile on a test of intelligence. [2] [3] [4] Forms 7 and 8 provide ...
