I am going to answer your question, but first I am going to say that the school did not care about the results at all. They did, however, want a copy of the personalized sheet (based on results) that said what my child should be working on now and what needed improvement, and the projected path through subjects (how many years ahead in math and so on). These things really impressed them.
The way it was explained to me is that the test was for kids already identified as gifted (top 2%) OR top 5% as recommended by a teacher. YMMV, I am sure.
