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).

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 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.
Additional scoring information includes percentile ranks, age equivalents, and a change-sensitive score (Janzen, Obrzut, & Marusiak, 2003). Extended IQ scores and gifted composite scores are available with the SB5 in order to optimize the assessment for gifted programs (Ruf, 2003).
The minimum accepted score on the Stanford–Binet is 132, while for the Cattell it is 148, and 130 in the Wechsler tests (WAIS, WISC). [13] Most IQ tests are designed to yield a mean score of 100 with a standard deviation of 15; the 98th-percentile score under these conditions is 130.8, assuming a normal distribution. [14]

An IQ below 70 In 2002, the Supreme Court ruled that executing someone with an intellectual disability violates the 8 th Amendment’s ban on cruel and unusual punishment.
In addition to VIQ, PIQ, and FSIQ scores, four new index scores were introduced: the Verbal Comprehension Index (VCI), the Perceptual Organization Index (POI), the Freedom from Distractibility Index (FDI), and the Processing Speed Index (PSI). The WISC-IV was produced in 2003. The WISC-V was published in 2014. The WISC-V has a total of 21 subtests.
