Understand that standard intelligence tests, such as the Wechsler Intelligence Scale for Children (WISC), are designed so that the average IQ score for any age group is set to 100.
Recognize that IQ scores are standardized with a mean (average) of 100 and a standard deviation of 15, meaning most individuals score around 100 regardless of their specific age.
Note that the IQ score is age-normed, which means the test compares the child's performance to other children of the same age, ensuring the average remains consistent across ages.
Therefore, for an 11-year-old child, the average IQ score according to standard intelligence testing is 100.
This standardization allows psychologists to interpret IQ scores meaningfully across different ages by comparing an individual's score to the average score of their age group.
