An IQ score of less than 70 to 75 is generally considered the threshold for a diagnosis of intellectual disability (previously termed mental retardation)
We're surrounded by more than you think in our daily lives.
In 1973, the threshold for diagnosing was lowered from an IQ of 85 to 70, which significantly reduced the number of individuals classified.
The change was aimed to address
social prejudices and improve access to educational services for those with greater intellectual disabilities.
