An intelligence quotient (IQ) is a total score derived from a set of standardised tests or subtests designed to assess human intelligence. [1] The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
Validity is the main extent to which a concept, conclusion, or measurement is well-founded and likely corresponds accurately to the real world.

IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient (IQ) tests, into categories such as "superior" and "average".

The Wide Range Intelligence test (WRIT) is an assessment of verbal (crystallized) and visual (fluid) IQ. Running at approximately 30 minutes, the WRIT is shorter than traditional IQ tests. The test also involves only four subtests and requires fewer physical materials than a typical test. It was created alongside the Wide Range Achievement Test ...

But if the purpose is to assess intelligence in a broader sense, the validity of IQ tests is questionable." [94] Some scientists have disputed the value of IQ as a measure of intelligence altogether.
