Hi Rachel,

At age three quantifying an IQ is generally not important.. most kids do well in school and in life without ever having an IQ test...

IQ test can benefit some kids who may benefit form differential programming during the school years... However, I generally do not recommend IQ assessment until age 4 1/2 or so - as IQ is more stable then and the information is more useful for school planning...

One of the few occasions where earlier testing may be warranted is when the information can be useful in differential diagnosis.. eg: a child is suspected of having an autism spectrum disorder - and an IQ test may provide additional insight into the child's profile that may help to explain some of the unusual behaviors others are seeing...

Hope that helps, Dave
