Having a certain degree of brain ability is of paramount importance to each job.

The question is how well your brain ability should be so that you can perform great in a job and how you can measure your mental ability.

In this article, you’ll learn about IQ scores and the suitable scores for yourself.

What is an IQ score?

The purpose of intelligence tests is to assess a person’s ability to solve problems and do reasoning tasks.

In fact, your IQ score is a representation of both fluid and crystallized intellect. In comparison to other people of your age, your IQ test result reveals how well you did on these tests of mental abilities.

This is a standardized method to know your mental ability, which is measured in comparison to a peer group.

There are different interpretations of IQ scores, but an IQ score between 90 and 109 indicates a normal or average intelligence. Actually, 100 is considered to be the theoretical average in the world.

Acceptable IQ scores

To know what IQ score is suitable for you, you’d better learn different ranges of IQ scores:

  • Definite “feeble-mindedness” or low: IQ scores under 70
  • Indicates dullness or “lower average”: IQ scores between 80 and 89
  • A normal or average intelligence: IQ scores between 90 and 109
  • Superior intelligence or above average: IQ scores between 110 and 119
  • Superintelligence or being gifted: IQ scores between 120 and 140
  • Indicates genius or nearly genius: IQ scores over 140

Apart from these categories, the average IQ score can be defined for different age groups. Here is the explanation for this categorization:

  • 16-17-year-olds

The average score for this age group is 108, which is the overall average.

  • 18-19-year-olds

The average IQ score is 105, which is still in the range of normal intelligence.

  • 20-24-year-olds

The average IQ score is 99.

  • 24-34-year-olds

The average score is slightly lower than the previous group at 97. This is still an average under 100, but after this age group, the average IQ score starts to go up.

  • 35-44-year-olds

The average IQ score for this age group is 101.

  • 45-54-year-olds

The average IQ score is 106.

  • 54-64year-olds

The highest average score, which is equal to 109.

  • 65-69-year-olds

The age group’s average IQ score is 114, which is superior intelligence or above-average.

  • 70-74-year-olds

The average score is 119, which is again more than the overall average score.
