Moderate mental retardation implies which level of intellectual functioning?

• A. Severe impairment
• B. Moderate impairment
• C. Mild impairment
• D. No impairment

Answer: (B)

Moderate level of intellectual functioning is what is indicated here. When someone is described as having moderate impairment, it means they have noticeable difficulties in thinking and learning that are greater than mild cases but not as severe as those with severe or profound impairment. In practical terms, individuals with a moderate level typically need support with complex tasks and daily living skills, but they can often learn to perform many routine activities and communicate at a basic level with help.

In terms of typical ranges, moderate impairment is commonly associated with an IQ roughly in the mid-30s to around 50–55, though adaptive functioning and ongoing support needs are the defining factors, not just the test score. The other options describe different levels of functioning: severe impairment indicates more substantial limitations, mild impairment indicates less severe limitations, and no impairment means typical functioning.
