An IQ test is a test of cognitive skills that produces an IQ score. This refers to an intelligence quotient, which is an estimate of general intelligence. IQ tests have multiple subtests to tap different kinds of intellectual skills, such as memory, vocabulary, reasoning, attention, and copying skills. Tests therefore can include lists of vocabulary words to define, arithmetic problems, or drawings to be copied. All subtests have both easy and hard items, and the items become more difficult as the test goes on. The score is based on the number of items answered correctly.

Some people question the usefulness of IQ tests because it is difficult to create a test that is not skewed somewhat by cultural biases.
