We applied and had just barely there scores and were asked for to reapply with more information. My son was accepted the second time, when we added qualifying achievement scores AND more work samples.
For the work samples, I included a video of him playing Monopoly (age 5 1/2) and being the banker, making change etc. My husband purposefully picked a "fight" so that DS had to explain himself on the video and the math. We had a video of him giving a tour of our staircase, where he had created a very elaborate treasure hunt based on hundreds of Pokemon cards he had created. I had a page of multiplication worksheets from school, a couple of photographs of him doing strange things on vacation and a copy of NWEA scores, even though they are not "accepted" testing.
You'll do better following her around with a video camera, doing less academic but more truly engaging tasks I think. Let her shine talking about learning to read music or a favorite science topic (or doing an experiment) or some other project that makes her really excited and happy.
