In the United States, certain [[Public policy (law)|public policies]] and laws regarding military service,<ref>{{cite report|url=https://www.rand.org/content/dam/rand/pubs/technical_reports/2005/RAND_TR193.pdf |title=Determinants of Productivity for Military Personnel|last=Kavanagh|first=Jennifer|date=2005 |publisher=RAND Corporation|location=Santa Monica, CA |isbn=0-8330-3754-4|access-date=1 July 2017}}</ref><ref>{{cite report |url=https://www.rand.org/content/dam/rand/pubs/monograph_reports/2009/MR818.pdf |title=Estimating AFQT Scores for National Educational Longitudinal Study (NELS) Respondents|last1=Kilburn |first1=M.

However, in the case of ''[[Griggs v. Duke Power Co.]]'' in 1971, for the purpose of minimizing employment practices that disparately impacted racial minorities, the [[Supreme Court of the United States|U.S. Supreme Court]] banned the use of IQ tests in employment, except when linked to job performance via a [[job analysis]]. Internationally, certain public policies, such as improving nutrition and prohibiting [[neurotoxins]], have as one of their goals raising, or preventing a decline in, intelligence.

A diagnosis of [[intellectual disability]] is in part based on the results of IQ testing. [[Borderline intellectual functioning]] is the categorization of individuals of below-average cognitive ability (an IQ of 71–85), although not as low as those with an intellectual disability (70 or below).

In the United Kingdom, the [[eleven plus exam]] which incorporated an intelligence test has been used from 1945 to decide, at eleven years of age, which type of school a child should go to. They have been much less used since the widespread introduction of [[comprehensive school]]s.
