To be clear, I wasn't questioning your dc's vocab score, frannieandejsmom

! If it lines up with where you feel his vocab to be, I'd be comfortable in your shoes saying that it was accurate. In my dd's instance, it did seem like a lowball estimate, though, and in the other child whose mom told me the score was so high's instance, I would be surprised if the vocab was actually that high. I could, of course, be wrong in gauging a kid's vocab on speaking with the child and him/her not knowing the meaning of spelling words.
