Which score indicates Intellectual Disability - extremely low range on the Wechsler Memory Scale?

• A. 70 or less
• B. 75-85
• C. 85-95
• D. 60-69

Answer: (A)

Scores on the Wechsler measures are normed so the average is 100 with a standard deviation of 15. A result at or below 70 is two standard deviations below the mean, which signals a very substantial level of impairment. In this context, that extreme low range is the threshold typically associated with intellectual disability, especially when memory problems are evident and there are broader adaptive-functioning deficits. So, a score at or below seventy best fits the idea of an extremely low memory-range profile linked to intellectual disability. Higher ranges (around 75-85 or 85-95) reflect mild to average levels of performance and don’t indicate the same level of impairment.
