This post is for teachers who are feeling confused in these data-driven times. If you are no longer being allowed to write your own tests and quizzes and you are no longer being allowed to select your material, your numbers may not be the best reflection of your performance. If you want to know how you are doing, look at your students. Talk to your students.
If your students pretty much know all the planets, their locations, how gravity works, and the various parts of the astronomy standards you may have been teaching, you are doing fine.
