The WISC-V takes 45 to 65 minutes to administer. It generates a Full Scale IQ (formerly known as an intelligence quotient or IQ score) that represents a child's general intellectual ability. It also provides five primary index scores, namely Verbal Comprehension Index, Visual Spatial Index, Fluid Reasoning Index, Working Memory Index, and ...
An IQ score of 115 means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. [5] This "deviation IQ" method is now used for standard scoring of all IQ tests in large part because they allow a consistent definition of IQ for both children and adults.
The reliability coefficients for the WPPSI-III US composite scales range from .89 to .95. The UK sample for the WPPSI-III was collected between 2002–2003 and contained 805 children in an attempt to accurately represent the most current UK population of children aged 2 years 6 months to 7 years 3 months according to the 2001 UK census data.
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
IQ scores can vary for the same person, so a person does not always belong to the same IQ score range each time the person is tested.

The test purports to assess students' acquired reasoning abilities while also predicting achievement scores when administered with the co-normed Iowa Tests. The test was originally published in 1954 as the Lorge-Thorndike Intelligence Test , after the psychologists who authored the first version of it, Irving Lorge and Robert L. Thorndike . [ 1 ]

The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160. 68% of participants in the UK standardisation sample obtained scores of 85-115 and 95% obtained scores of 70-130.
