Does IQ change with age?
A person’s IQ does not change with age. In other words, if you take an IQ test now and then another 10 years from now, your IQ score will likely be very similar. See the article : Who has an IQ of 300?. This is because IQ is always measured relative to other people your age.
At what age does IQ become stable? The average child‘s IQ is not stable until around four years of age. In children who were born prematurely or who have significant health problems, it can be much later.
Is IQ genetic?
Researchers have previously shown that a person’s IQ is heavily influenced by genetic factors and have even identified specific genes that play a role. They have also shown that performance in school has genetic factors. However, it was unclear whether the same genes that affect IQ also affect grades and test scores.
Is IQ natural or upbringing? IQ development shifts from parenting (environmental) influences to natural (genetic) influences as children enter adulthood around the age of 12 to 16 years.

What percent of IQ is genetic?
Early twin studies in adult individuals have found IQ heritability between 57% and 73%, with some recent studies showing IQ heritability as high as 80%. IQ goes from being weakly correlated with genetics in children to being strongly correlated with genetics in late teens and adults. See the article : What is the average IQ?.
