Hi all I am new here and have a question on the CogAT and NNAT.

My son is 5 and in kindergarten at a public school. He was referred for testing by his teacher to see if he qualified for the g&t program. They look at CogAT, NNAT and MAP scores.

We got the scores back and though he did well on the NNAT and his MAP scores were high he did only average or maybe slightly above on the cogAT so was not accepted into the program.

Scores:
CogAT V-118
CogAT q-110
CogAT nv-119
NNAT 136
MAP-R-99%+
MAP-M-99%+

My question is, given the discrepancy in scores between the two tests and the fact his NNAT is in the 99% should I seek a full battery IQ test? I am okay with him not getting into the program so am not going to appeal but wonder if I should get more information for the future and to better understand his learning needs.

It does not suprise me his NNAT was high as he has always excelled at puzzles, has been drawing mazes since age 3, etc. but I am not sure I see him as a true VS learner. He taught himself to read at age 4 and seems to do well so far in school. He is in an accelerated reading program and his teacher has him at an instructional level of 2nd grade for math and reading. But I realize if he is a true VS learner it may cause issues in the future and wonder if I should explore this further?

I guess I also wonder is it possible he is gifted and the CogAT did not for whatever reason identify it? Or is he just strong in visual-spatial tasks but not gifted in any other area? Or could the NNAT score have just been a spike and not indicative of anything?

I would love some opinions as my husband thinks there is no reason to seek additional testing but I am not sure. I like to be proactive and wonder if a full scale IQ test would identify any potential problems or give us more insight into his learning needs.

Thank you all for taking the time to read this. I really appreciate it.
