My son scored 139 in NNAT, whereas the benchmark score in second grade GT is 132.He had also got many "O"'s in his report card and he is also a good artist and his art is also been published in newspaper. Apart from this there are many other qualities to be considered for GT.

But we have received a letter stating he is not selected for GT. There is no proper reason mentioned. Will anyone let me know how they grade gifted talent? How should I proceed?
