As recently as 40 years ago, the condition was defined primarily by IQ scores, with a cutoff of about Although an IQ of is normal--is often considered a rough standard of retardation, psychologists point to many people with such low test scores who are able to live independently, hold down jobs, marry and have families. That difficulty casts what appears to be a straightforward decision by the Supreme Court in a vastly muddier light.

IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient IQ tests, into categories such as "superior" or "average". In the current IQ scoring method, an IQ score of means that the test-taker's performance on the test is of average performance in the sample of test-takers of about the same age as was used to norm the test. An IQ score of means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to , and about 5 percent of the population scores above i. When IQ testing was first created, Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure. Variability in scores can occur when the same individual takes the same test more than once. Even before IQ tests were invented, there were attempts to classify people into intelligence categories by observing their behavior in daily life. Some early intelligence classifications by IQ testing depended on the definition of "intelligence" used in a particular case. Current IQ test publishers take into account reliability and error of estimation in the classification procedure. IQ tests generally are reliable enough that most people 10 years of age and older have similar IQ scores throughout life. IQ test publishers use large and "representative samples, use items that measure their intended constructs well, and produce unbiased scores. Thus, these instruments tend to provide scores that reliably and validly measure the constructs they intend to measure. For example, many children in the famous longitudinal Genetic Studies of Genius begun in by Lewis Terman showed declines in IQ as they grew up.

Experts divide the types of cognitive impairment into four categories: mild intellectual disability, moderate intellectual disability, severe intellectual disability, and profound intellectual disability. The degree of impairment from an intellectual disability varies widely. DSM-V places less emphasis on the degree of impairment i. IQ scores and more on the amount and type of intervention needed. While IQ scores are still relevant and important in assessing the level of intellectual disability, the new DSM-V adds another layer of diagnostic criteria Intellectual Disability: Causes and Characteristics. Mental health professionals must consider the person's ability or impairment across three skill areas: conceptual, social, and practical life skill.
