IQ tests measure mental ability and provide a score to show how a person’s results compare to others in their age group. IQ encompasses a range of mental abilities, including verbal reasoning, visual abilities, spatial awareness, processing speed, and pattern recognition.
IQ tests are standardized, with a mean score of 100 and a standard deviation of 15. Here are some IQ score ranges:

The IQ scale is important to the test because it is how you discover the results post-testing. The importance of using an IQ test to determine intelligence has its pros and cons. We will cover that in a later section.
The importance of IQ tests is debatable. Online versions are fun to take, but you should take the results with a grain of salt because they are not always the most accurate displays of a person’s intelligence.
What is a Good IQ Score for Your Age?
A complete breakdown of how to calculate IQ scores will be explained later in this article. However, a good IQ score for your age would be 100 or above.
Does IQ Increase with Age?
For the most part, IQ does not increase with age. As mentioned, the scale reflects results based on the test taker’s age. So, as long as the person is growing chronologically and mentally in the same upward trend, their IQ should be the same for their entire life.
What Causes IQ to Drop?
A decrease in IQ is usually due to some form of mental trauma, in most cases physically, but in other cases mentally. There is some evidence to suggest environmental factors like an increase in online time, changes in nutrition, the manner of education, and less reading in society overall.
Is Your IQ Genetic or Learned?
Intelligence seems to be largely genetic, though some environmental factors can affect this. Studies on sets of twins have shown that about 60% of the factors determining a person’s intelligence and aptitude in learning environments come from genetics.
When Does Your IQ Peak?
As mentioned, most people should have a similar IQ level throughout their lifetime. However, it is possible that children and young teens can grow their IQ as they continue to learn in educational systems and develop biologically. When you become an adult, your IQ tends to peak at about 20 years old.
