Would they accept an outside assessment? Do you have any other test scores or achievement scores available to prove your point?
Our district uses the Naglieri for ID of GT kids. And that is the only tool they use. 122 on the NNAT is still a quite respectable score, 100 being the mean. The NNAT is cheap and easy to administer to large groups of kids, and that is why many districts use it. It can easily identify ELL as gifted. However, you aren't at a disadvantage taking it as a English speaker or as a not disadvantaged student. It measures some very finite skills and there are many reasons a child may not do well on a test like this in a group setting. But knowing many, many peoples NNAT scores, I tend to think those from higher income families still average better.
It also depends on what the GT program would consist of. I think our district is over ID-ing kids with the NNAT in some cases and missing kids in other cases. But the only real gifted magnet school they have is highly tailored to be great for visual-spatial kids. Some less v-s kids end up finding it not a good fit at some point, even though it is very much a school for the moderately gifted. You may want to look at the programming and make sure it's worth the battle. A GT math-science program COULD be very particular to more v-s gifted kids. There might be very mathy kids that wouldn't be a good fit in the English G-T programming. It just depends on the programming and the child. And whether or not you think that NNAT score accurately reflects your daughter's math/science abilities in particular, even though her verbal abilities are very high.
Good luck!
