Who out there believes that value added scores actually measure how well you are teaching? If only you had differentiated more. If only you had been more engaging. If only you had used more group work, done less direct instruction, and used more rigor. Many people within the education field, and even more outside of our profession, believe that student test scores tell us the whole story. They don’t.
Unfortunately, everyone today has an obsession with test scores, benchmark scores, pre and post-test scores, and more baloney. Not that all of these are horrible, there is just too much of it
