I don't agree, but what does your text say?
intelligence tests under 7 years have little predictive value ....
what do you think
I agree more with age 10, but you need to put down what your text says.

One man I worked for in the projects and programs office in our district once told me that when we test kids (especially for gifted programs) before grade 3, we're really testing their parents! I since read that same idea in various education journals.
