You might have heard about IQ and its role in people’s success. In this article, we’re going to let you know what IQ is, how it can be measured, and what IQ score is suitable for different people.

The IQ score definition

IQ stands for Intelligence Quotient and is a measure of a person’s ability to solve issues and perform thinking activities. This factor is determined using IQ exams, and your IQ scores let you know how smart you are.

In reality, your IQ level reflects both fluid and crystallized intelligence. Your IQ test result indicates how well you perform on various mental activities compared to people of your age.

This is actually a standardized way of determining your mental capacity in comparison with a peer group.

IQ tests can be interpreted in a variety of ways, but a score of 90 to 109 indicates normal or average intellect. In fact, 100 is thought to be the world’s theoretical average.

Different ranges of IQ scores

To figure out what IQ score is best for you, familiarize yourself with the following IQ ranges:

  • Low or definite “feeble-mindedness”: IQ scores of less than 70
  • Dullness or a “lower-than-average” performance: Scores of 80 to 89 on the IQ scale
  • Intelligence that is typical or average: IQ scores ranging from 90 to 109
  • Above-average intellect or superior intelligence: IQ scores ranging from 110 to 119
  • Being gifted or having superintelligence: Scores of 120 to 140 on the IQ scale
  • Genius or brilliance: IQ scores of 140 or higher

Average IQ scores required for different age groups

It’s well-established that the average IQ score can be defined differently for different age groups.

The following data is the rationale for this classification:

  • For people aged between 16 and 17

The average score is 108, which is equal to the overall average.

  • For people aged between 18 and 19

The IQ score for this age group is 105, which is still in the range of normal intelligence.

  • For people aged between 20 and 24

The average IQ score is 99.

  • For people aged between 24 and 34

The average score is 97, which is a little lower than the preceding group. Although the average IQ score is still below 100, following this age group, the average IQ score begins to rise.

  • For people aged between 35 and 44

This age group’s average IQ score is 101.

  • For people aged between 45 and 54

The average IQ score in the United States is 106.

  • For people aged between 54 and 64

The highest average score, 109, was obtained.

  • For people aged between 65 and 69

The IQ score is 114, which indicates exceptional intellect or above-average intelligence.

  • For people aged between 70 and 74

The average score is 119, which is higher than the average score across the board.
