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 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.

In short, while diagnosis of any childhood or adult difficulty should never be made based on IQ alone (or interview, physician examination, parent report, other test etc. for that matter) the cognitive ability test can help rule out, in conjunction with other tests and sources of information, other explanations for problems, uncover co-morbid ...
Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and PSI. The WAIS-IV can generate an FSIQ in the range of 40 to 160. General Ability Index (GAI), based only on the six subtests that the VCI and PRI comprise; it is intended to portray a snapshot of general intelligence that is less influenced by working memory ...
These ideas included things such as discouraging individuals with low IQ from having children and granting important positions based on high IQ scores. While there was significant opposition, many institutions proceeded to adjust students' education based on their IQ scores, often with a heavy influence on future career possibilities (Leslie ...
Citing a disproportionate number of students scoring in the 99th percentile — the far right tail of the distribution curve — the NYC DOE replaced the Bracken (BSRA) with the Naglieri Nonverbal Ability Test (NNAT), and changed the weighting, lowering the OLSAT from two-thirds to one-third and giving the NNAT two-thirds.
The NNAT has been found by one study to show excessive score variability, with within-grade standard deviations reaching as high as 20 points. This has the effect of both overrepresenting and underrepresenting index scores - that is, more students received very high or very low scores than expected.
