Generally, it is relatively normal for a 6-year-old child's IQ to be between 80 and 120, and an average value of 100 plus or minus 15 is within the normal range. If the IQ is lower than 70, it can be regarded as a sign of mental retardation.

However, according to the different constitutions of different children, the treatment of injuries will also be different, and 6-year-old children can increase their intelligence. If it is found that the child's IQ is a little abnormal, such as being too active, If the symptoms are quiet, you can do more things to cultivate the child's sentiment and improve the child's IQ.

First of all, the normal IQ range is 70-130, with an average of 100. A person below 70 is considered to have a low IQ.

But first of all, the child’s mental age and actual age are generally not less than seventy. You can give him a test, but the test does not guarantee lifelong success. A child's normal IQ depends on normal development level, genetic metabolism, and acquired physical and mental intelligence development. Therefore, if a child's IQ is low, it may be caused by abnormal brain development and other reasons.

The normal IQ range is 70-130, with an average of 100. A child with an IQ below 70 is considered to have low IQ. However, in order to diagnose mental retardation in children, in addition to having an IQ below 70, they should also have low social adaptability. The test of IQ provides valuable reference information for medical treatment and education, but the result of one IQ test cannot be used to "determine life".

On the one hand, the child's mental state during the test is related to the test results; on the other hand, the test results can only reflect the recent level. The longer the time interval, the less closely related it is.
