My dd took the Explore though NUMATS too. I think that we are supposed to get more info next month, something that will tell us how they did compared to other kids their age. Until then I have been using this site. http://bbc.honors.uiowa.edu/talentSearch2009/ It doesn't quite work for us as my dd is only 3rd grade, but it does give some info. I can tell you that my dd also got a composite of 17, and it says that it is the 93% for 4th graders taking the test. Sounds like both of our dd's did pretty well.

To be honest, it totally blew me away. No wonder I pull my hair out trying to find curriculum for her (we homeschool).
