What is considered a “good” IQ score?

IQ scores are typically scaled so that the average score is 100, with a standard deviation of 15 points. Scores between 90 and 110 are considered average, while scores above 130 are often considered high. However, it’s important to remember that IQ scores are just one measure of intelligence and should not be taken as the sole determinant of a person’s potential or abilities.
