Results of the NAC

In order to increase transparency, we are publishing the scores and ranks of students that took part in the National Astronomy Competition. We asked for students consent when publishing the scores. Note that anyone can take part in the National Astronomy Competition but only U.S. citizens and residents can represent U.S. at the International Astronomy and Astrophysics Olympiad.
