Full Scale Intelligence Quotient (FSIQ) Score Chart

Calculating the full-scale IQ (FSIQ) score involves adding together the scores of specific subtests from a cognitive assessment, such as the WAIS-IV. The WAIS-IV has 10 core subtests that measure verbal comprehension, perceptual reasoning, working memory, and processing speed. Each subtest is scored separately, and the FSIQ score is then calculated by combining these individual scores. This combined score reflects overall cognitive ability compared to the general population.

IQ scores represent an individual's cognitive ability based on standardized IQ tests, while percentile ranks show how that IQ compares to the general population. For example, a score in the 75th percentile means the individual scored higher than 75% of people in their age group.

There is no specific "good" full scale IQ (FSIQ) score as it can vary based on individual factors and context. For example, a score of 110 may be considered average in the general population, but for someone with a learning disability or intellectual impairment, it could be considered above-average. Additionally, FSIQ scores should not be used as the sole measure of intelligence, as they do not capture other important aspects such as creativity and emotional intelligence.
