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.

For the 2020/2021:

95 students took part in the NAC. We again administered the exam online with the help of many volunteers. The mean score was a 55.02 out of 180 with a standard deviation of 29.99, and the median was 54.50. Below are the full results and histogram.
