Thanks aeh…

Yes, it does seem like the non verbal part of CogAT and the NNAT3 test are similar, but his results were different.

It might have come down to the fact that he gave it a better effort that day. Or that he knew performing well on this test would give him more opportunities. Or maybe because the test was given individually without classroom distractions. Who knows. I am seeing the testing as just a door way to unlock more opportunities for him.
