Is an IQ score of 128 for a 4 year old good?

Answer 1

It is significantly above average

IQ is considered to be invariant with age. Thus it is expected that if tested repeatedly at various ages he would continue to test at about 128 plus or minus a few points each time.

128 indicates your 4 year old is capable of handling ideas 28% above his average age group, in other words at this time that of average 5 year olds.

However, remember that the only thing proven about high IQ scores is they indicate an ability to score high on IQ tests.

Answer 2

An IQ score of 128 is above average for a 4-year-old. It suggests above-average intelligence compared to other children of the same age. However, keep in mind that IQ scores are not the only measure of a child's abilities and potential.

Answer 3

A 'good' IQ score is relatively subjective. Age isn't a factor, IQ is assumed to remain static across the lifespan. The average score is 100, anything above that mark is above average. There are pros and cons to having high intelligence (130+), so its really up to you what you consider to be good.
