For decades, people have tried to differentiate themselves based on their IQ, or Intelligence Quotient, and there are tens of different tests designed to check and “rate your intelligence”. These tests are highly controversial, as many people say that wits and intelligence are two radically different things. One thing is for sure, though: you can easily train your intelligence in the long run, provided that there is no congenital defect that prevents you from doing so.

When it comes to the average IQ, it usually tends to range between 85 and 115 and it varies greatly from one country to another. The chronological age and the mental age of the subject can also determine the average intelligence for a particular person, given the fact that this is highly individual. If you believe that you or your child may have a lower IQ than average, then here are some of the most common signs you should pay attention to:

1. General Signs Of Low IQ In Children And Teenagers

Children and teenagers display different signs of low IQ than adults do, and that is a known fact. As a parent, it is important to pay attention to these signs and to recognize them: if your child has very poor social skills in play-learn situations, poor dressing and feeding skills as well as delayed hygiene and self-care, then he or she is likely to have a lower IQ than average. On the other hand, teenagers who often have poor job skills or difficulties in learning various academic skills may also have a lower IQ than the vast majority of the people.

Most of the time, these symptoms appear before the child turns 18 years of age, and the signs can vary greatly depending on just how low the IQ really is. An IQ that is under 70 is widely considered to be an intellectual disability.

2. Signs Of Mild Intellectual Disability

There are three types of intellectual disability: mild, moderate and severe. Those who experience mild intellectual disability usually score lower than average on IQ tests at school, they have difficulty communicating and socializing with other people and they are often unable to think logically. Generally, these people display signs of low IQ very early on, when they are unable to learn and to develop at the same rate as other children of the same age.
