What IQ score is generally considered a threshold for intellectual disabilities (ID)?

The threshold for intellectual disabilities (ID) is typically defined as an IQ score of 70 or below. This standard is grounded in various diagnostic criteria, such as those from the American Psychiatric Association, which identifies this range as indicative of significant limitations in intellectual functioning. Individuals with an IQ score at or below this level often demonstrate challenges in adaptive functioning, which includes difficulties with everyday tasks such as communication, self-care, and social interaction.

This score is part of a broader understanding that intellectual disabilities encompass both intellectual impairment and the impact of this impairment on day-to-day living skills. Scores above this threshold do not meet the criteria for ID, as they suggest a level of cognitive ability sufficient to manage personal and social responsibilities more effectively. Thus, recognizing the significance of the 70 score helps professionals identify and provide necessary interventions for those who truly require support.
