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