Intelligence Quotient, or IQ, is a theoretical construct used by psychologists within standardized tests as a means of describing one’s intelligence level. It is the psychological measure of a person’s “intelligence quotient” (IQ)  and these tests come in many forms. They can help diagnose intellectual disabilities or measure someone’s intellectual potential. An IQ test may be the first step in diagnosing intellectual issues. IQ tests involve the measure of two primary components — verbal and performance. When an IQ test is scored, three primary scores are obtained — verbal IQ, performance IQ, and the full scale IQ. The full scale IQ is what is commonly referred to as one’s IQ score. Because the performance portion of the IQ test requires physical manipulation of objects in front of the testing psychologist, a legitimate IQ test cannot be taken online.
