Weâve all heard of the term IQ (or Intelligence Quotient). But what does it really represent and how significant is your or your childâs score is an IQ test? What does it really mean to have a low, moderate, or high IQ? A standard IQ test is designed to measure a personâs performance relative to their peers, most commonly, their age group. This is particularly the case with children and adolescents.
Historically, IQ is a score obtained by dividing a personâs mental age score, obtained by administering an intelligence test, by the personâs chronological age, both expressed in terms of years and months. The resulting fraction is multiplied by 100 to obtain the IQ score. When current IQ tests were developed, the median raw score of the norming sample is defined as IQ 100 and scores each standard deviation (SD) up or down are defined as 15 IQ points greater or less, although this was not always so historically.
