I also have a similar case. My daughter has scored 138 in NNAT and 128 in COGAT. Her work is also published in newspaper and she has got very good grade in her report card and from her teacher also. Even then they have refused GT.
They are suggesting me to take another test(psychological) in GMU,
which is optional to appeal for GT board. I do not understand why she should take this test, if she had surpassed the benchmark score already.

Even if they deny GT, why can't they give some proper explanation such as what factors they considered, what is she missing?
If they just say gifted skills why do they need a benchmark score to test the intelligence of kids rather than gifted skills alone?
Who is the responsible person to give me a proper figure as I strongly feel as a parent I should know more info about my kid?
