How accurate are IQ tests for 3 year olds?
My son has apraxia (speech disorder). Apraxia is a psych-motor problem that allows him to hear/understand but he cannot speak more than 2-3 word sentences. His brain cannot fully coordinate with his tongue. (See apraxia-kids.org). He also has balancce / coordination / fine motor skills issues. He is being placed in a special program but was test for an IQ that came out at 70. My wife is worried over it but I don't think an IQ test can tell much at that age, especially with his condition. Hence, the summary question is "How accurate are IQ tests for 3 year olds?"
