What IQ testing did for us was promote awareness, and give concrete numbers to represent what we were seeing at home and at school. Schools are typically data-driven. In our situation, the numbers spoke much louder than words.
Just chiming in here. We were stunned earlier this school year by how a few test results, sent to the school ahead of our meeting, seemed to focus the conversation.
It also gave us as parents some confidence that we weren't reading too much into her behaviors; a solid footing, if you will.
It happens, and if you can bear to read this forum for months, I believe that there is a pretty good chance that it happend in your family.
I would concur.
