Which range on the Wechsler Memory Scale may indicate high average intelligence?

• A. 110-119
• B. 100-109
• C. 120-129
• D. 130+

Answer: (A)

On the Wechsler measures, including the memory scale, scores are standard scores with a mean of 100 and a standard deviation of 15. A score in the 110–119 range sits about one to a little more than one standard deviation above average, indicating memory performance that is clearly above average. This level is often interpreted as high-average functioning, which can align with higher overall cognitive ability without being in the “very high” or “exceptional” ranges. Scores in the 100–109 range are still considered average to mildly above average, while 120–129 would be categorized as superior, and 130+ as very superior. So the 110–119 range best matches “high average,” given the usual interpretation of these norms. Keep in mind the memory scale reflects memory abilities, not intelligence in a broad sense, though stronger memory often accompanies higher cognitive functioning.
