IQ reference charts are tables, suggested by psychologists to divide intelligence ranges into various categories[1][2]. As reference charts, they are not to be taken as absolute or very precise. The reason for this is the lack of a uniform definition of intelligence and the current inability to wholly quantify it in a scientific manner. To get a "true" IQ score, multiple IQ tests must be taken since professionally administered IQ tests are only roughly 96% accurate.[3] The average of multiple tests, usually at least three, is considered that person's "true" IQ score. However, these tests must be taken within a relatively short period of time, normally under one year for three or more tests.
