IQ scores can differ to some degree for the same person on different IQ tests, so a person does not always belong to the same IQ score range each time the person is tested (IQ score table data and pupil pseudonyms adapted from description of KABC-II norming study cited in Kaufman 2009).

The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests yielding scaled scores that sum to derive the Full Scale IQ. With the WAIS-IV, the verbal/performance IQ scores from previous versions were removed and replaced by the index scores.
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.
The resulting IQ standard score is the subject of much investigation as psychologists check correlations between IQ and other life outcomes. The Wechsler IQ tests for adults and for children have long been regarded as the "gold standard" in IQ testing. [1] fMRI data showing regions of activation
In psychology, human intelligence is commonly assessed by IQ scores that are determined by IQ tests. In general, higher IQ scores are associated with better outcomes in life. [11] However, while IQ test scores show a high degree of inter-test reliability, and predict certain forms of achievement effectively, their construct validity as a ...

The mean reliability of the subtests of the SON-R 2,5-7 is 0.72 and the reliability of the total IQ score is 0.90. For the SON-R 6-40, the mean reliability of the subtests is 0.87 and the reliability of the total score is 0.95. The reliability and stability of the scores increase as the age of the participants increases.
Leiter International Performance Scale or simply Leiter scale is an intelligence test in the form of a strict performance scale. It was designed for children and adolescents ages 2 to 18, [1] although it can yield an intelligence quotient and a measure of logical ability for all ages.
