The threshold for what was then called "mental retardation" (now intellectual disability) was lowered in 1973 by the American Association on Mental Deficiency (AAMD, later AAMR/AAIDD) from an IQ below ~85 to below ~70. files.eric.ed.gov This aligned the definition with "significantly subaverage" intellectual functioning—roughly the bottom 2% of the population (two standard deviations below the mean of 100), rather than one standard deviation (~16% of the population). files.eric.ed.gov Main Reasons for the ChangeReducing overdiagnosis and stigmatizing labels: An IQ cutoff of 85 included many people who were simply "below average" but functioned adequately in daily life. Lowering it avoided broadly applying the "retarded" label (which carried heavy social prejudice and stigma at the time) to a large portion of the population. hrw.org Addressing overidentification of minority students in special education: This was a key factor during the civil rights era. There was growing concern about disproportionate placement of minority (especially Black) children in special ed classes based on IQ tests, which some viewed as culturally biased or leading to inappropriate labeling. Black Americans' average IQ is around 85, so roughly half scored below the old 85 threshold—leading to high rates of classification as "borderline" or mildly retarded. The change reduced this dramatically (e.g., from ~50% to ~12-16% below the new line for that group). ncbi.nlm.nih.gov Focus on adaptive behavior: The 1973 definition (from the AAMD manual by Grossman) required not just low IQ but also deficits in adaptive functioning (practical, social, and conceptual skills). This made diagnosis more clinically meaningful rather than purely statistical. cga.ct.gov The shift was part of broader 1960s-1970s movements toward deinstitutionalization, civil rights for people with disabilities, and critiques of IQ testing (e.g., cases like Larry P. v. Riles highlighted IQ test misuse with minorities). catalogimages.wiley.com Context and EffectsPrior to 1973, the cutoff had been around 85 since the 1950s (or earlier in some systems). The change eliminated the old "borderline retardation" category (IQ 70-85) and significantly reduced the number of people eligible for certain services or labels—though this sometimes limited access to support for those in the 70-85 range who might still need help. ncbi.nlm.nih.gov Later refinements (e.g., 1992) allowed some flexibility up to ~75 with adaptive deficits, and modern definitions (DSM-5, etc.) emphasize both IQ (generally <70-75) and real-world functioning rather than a rigid number. IQ tests also have a standard error of measurement (~3-5 points), so cutoffs aren't absolute. hrw.org
