Iq percentile calculator



    • What is the highest possible IQ score?

      IQ tests are used to measure a person’s intelligence and find out if they have special skills or abilities. Most iq tests score an individual on a scale of 100. The highest score possible is 145, and the lowest score possible is 61; scores between these two extremes represents just one standard deviation from the mean iq for that group.


    • How do you interpret an IQ score?

      IQ scores are calculated by taking the individual's mental age (as measured by the Stanford Binet test) and dividing it by their chronological age. This number is then multiplied by 100 to yield the IQ score. So, if someone has a mental age of 20 and is chronologically 10 years old, their IQ would be 200.
