Is 117 IQ for a 8 year old boy good?

IQ tests take your age into account so IQ usually does not change as you age. An IQ of 100 is average so an IQ of 117 is considered "bright normal". However remember that IQ tests only measure one area of intelligence: Problem Solving/Logical Reasoning. There are eight areas of intelligence so if you have an average IQ, you can still be considered highly intelligent. Also, IQ tests can be inaccurate. Albert Einstein had an IQ of 160. If you really think about it, it's not that high.
