What is an IQ test?

IQ test which is also known as ‘Intelligence Quotient’ test, comes in various forms. It was first used in France to diagnose students with learning disabilities so they receive what nowadays is called special education. At the present time, an IQ test is not only used to identify those with mental disabilities but also to identify those who are intellectually gifted.

How is my IQ test score calculated?

An IQ Test score is calculated based on a norm group with an average score of 100 and a standard deviation of 15. The standard deviation of 15 means, 68% of individuals have scored between 85 and 115 on the IQ test. This means the average score will always be 100 and 95% of individuals will score between 70 and 130.

High IQ test scores:

Based on the bell curve, an IQ test score of 100 is considered the average and typically a score above 100 is associated with high intelligence. IQ test scores ranging from 130 and above are considered to be in the extreme intelligence category while those with an IQ higher than 140 are considered gifted.

Low IQ test scores:

Those who score below 85 are considered to be associated with low intelligence. A score below 70, is usually considered mentally handicap and may indicate an underlying learning disability. Note : A high IQ test score doesn’t mean that someone is particularly smart, but it means that the person has “potential”.
