IQ level of intelligence 90-109 is: March 2013 (c, g)
**Core Concept**
The question is testing the understanding of the normal range of intelligence quotient (IQ) scores in children. Intelligence quotient is a standardized score derived from a series of tests designed to measure human intelligence, often used to assess cognitive abilities in children and adults. The normal range of IQ scores is typically considered to be between 85 and 115.
**Why the Correct Answer is Right**
An IQ score of 90-109 falls within the normal range of intelligence. This range indicates that the individual's cognitive abilities are within the average range, with scores above 115 indicating above-average intelligence and scores below 85 indicating below-average intelligence. The Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scale for Children (WISC) are two commonly used tests that assess cognitive abilities in children and provide an IQ score.
**Why Each Wrong Option is Incorrect**
**Option A:** "Borderline" is incorrect because it typically refers to an IQ score range of 71-84, which is below the average range. Individuals with borderline intelligence may require special education or support to develop their cognitive abilities.
**Option C:** "Low normal" is incorrect because it is a vague term that can refer to various IQ score ranges, but it is not a standard classification used in intelligence testing. This option is too ambiguous and does not accurately describe an IQ score of 90-109.
**Option D:** "Superior" is incorrect because it typically refers to an IQ score range above 115, indicating above-average intelligence. An IQ score of 90-109 is well within the normal range and does not indicate superior intelligence.
**Clinical Pearl / High-Yield Fact**
It is essential for pediatricians and healthcare professionals to understand the normal range of IQ scores to accurately assess and classify children's cognitive abilities. A thorough evaluation of a child's developmental and educational needs should be conducted to determine any potential learning disabilities or cognitive impairments.
**✓ Correct Answer: B. Normal**
