Hello, I am pretty new here as well. I posted a few posts down about what kind of testing to use on my DS, who is 4 as well. You may want to check it out because there was good advice and feedback from others. We plan to get him tested in the spring with the Binet. So I am not a great help as we haven't had him tested yet...but will in the spring. I had been really on the fence about testing him at all...but now I feel pretty good about it and confident that we are making the right decision to help understand him and get him whatever resources we can as soon as he starts school. Hope that helps.
