Mental Age (MA)is an intelligence test score, expressed in units of chronological age for which a given level of performance is average or typical when compared to people of the same age.

How mental age is derivedEdit

After taking a standardized test, an individual's mental age is divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.

Louis Leon Thurstone was among prominent critics, stating "the mental age concept is a failure in that it leads to ambiguities and inconsistencies."
