Getting accurate IQ test results with little kids is known to be challenging. Little kids do what they want to do and react in ways that even older kids don't. They might shut down because they don't like the tester's voice or clothes. Maybe they start getting scared. Or maybe those blocks over there are more interesting. Or:
Oh look! I see a bunny outside the window! I wonder if he's looking for carrots. I don't like that question. And I don't feel like doing this stuff. "Miss tester lady, do you have any carrots?"
That said, what are your motivations for testing a three-year-old? I imagine that early entrance criteria are based on testing at school to see if a child has the skills required for kindergarten entrance. Personally, if you believe he needs early entrance to K, I'd talk to the schools to find out what their criteria are. Are you sure the local schools even allow early entrance to K? Many don't. Finally, is this something your son wants or needs? Would he be harmed by NOT going to K early? There wasn't a lot of information in your OP, so it's hard to understand what's going on.
Personally, I agree with the suggestions to support his development and ensuring that what you do is for
him, not
you.
For example, if you do academic-type activities are they largely requested by him, or are you the main driver?
