Answer: Intellectual disability is identified by problems in both intellectual and adaptive functioning. One can't always tell if a person has an intellectual disability by looking at them.
Explanation:
- Individually administered and psychometrically reliable, comprehensive, culturally relevant, and psychometrically sound IQ tests are used to assess intellectual performance. 
- While a precise full-scale IQ test result is no longer required for diagnosis, standardized testing is employed in the process. 
- A full-scale IQ score of 70 to 75 implies considerable intellectual functioning limitations. 
- However, the IQ result must be read in light of the individual's challenges with general mental ability. 
- Furthermore, subtest scores might fluctuate significantly, thus the full-scale IQ score may not adequately indicate total intellectual functioning. 
- As a result, clinical judgment is required when evaluating IQ test results.
