Intellectual Disability is classified by IQ scores, indicating varying degrees of severity. The "Profound Level of Intellectual Disability" signifies the most substantial cognitive impairments.
The defined levels of Intellectual Disability are:
| Level | IQ Range |
|---|---|
| Mild | 55-70 |
| Moderate | 35-40 to 50-55 |
| Severe | 20-25 to 35-40 |
| Profound | Below 20-25 |
Consequently, an IQ score under "Below 20-25" designates a Profound Level of Intellectual Disability, reflecting the most significant limitations in intellectual and adaptive functioning.
