What level of Intellectual Disability has an IQ score in the 50-35 range?

• A. Mild Intellectual Disability
• B. Severe Intellectual Disability
• C. Moderate Intellectual Disability
• D. Profound Intellectual Disability

Answer: (C)

Levels of intellectual disability are defined by IQ ranges. Mild is usually about 50–70, moderate about 35–49, severe about 20–34, and profound below 20. The range given (50–35) spans values that are in both mild and moderate, but the central portion of that span falls into the moderate range (35–49). So the level that best describes an IQ in that span is Moderate intellectual disability. Keep in mind that an IQ of 50 sits at the upper end of mild, but when considering the full 50–35 range, moderate is the best fit.
