Hi, Amber. Would it be possible to get the testing paid for by insurance, due perhaps to the ADHD possibility?
I don't think that DYS would be likely to provide enough of a benefit in your situation to make that a major consideration (i.e. child at age 6 and homeschooling, which negates the programs available later as well as advocacy). However, if it would be a major benefit to you to hook up with other DYS kids and parents in your area, and you're in a fairly densely populated area to make that likely, it could still be worth it. In any event, Explore would be a cheap way to test in on achievement later.
I've read that some children don't perform to their full potential on the WPPSI due to characteristics of the test itself, but mostly older children. Still, your son could well have just had a bad testing day-- and at 4 it was probably his first testing experience, so everything might have been strange and a bit scary to him. You're certainly in the ballpark for a 145 score on the WISC-IV, especially with the variability of early testing results and the fact that it will have been going on two years between tests.
In summary: it all depends.
