PL1 is a PSSAR tool used to determine which domain?

• A. Intellectual disabilities
• B. Language development
• C. Memory function
• D. Motor coordination

Answer: (A)

The main idea here is understanding what the tool is designed to measure. PL1, as part of the PSSAR framework, targets general intellectual functioning—how a person thinks, learns, reasons, and solves problems. That broad assessment of cognitive capacity is what helps determine whether there is an intellectual disability, which centers on deficits in intellectual functioning and adaptive behavior.

Language development, memory function, and motor coordination are separate areas of functioning. They’re important, but they’d be assessed with tools focused specifically on those domains. The PL1’s purpose is to gauge overall cognitive ability, not isolate language, memory, or motor skills. That focus makes it the best fit for identifying the intellectual disabilities domain.
