I have the greatest teachers who work hard to prepare us for success. To have their own successes measured by a little black oval seems grossly negligent. Some students are great at taking tests. Some are not. Teachers should not be penalized for this, especially when some students are trying to do their best.
Testing is just one way to measure what a student knows.
My teachers refer to learning styles that individualize the way we learn. All of us do not learn the same way, so it is easy to see why our testing styles should be different also. Just because a school's grade might drop a letter does not mean my teachers are not working hard and that students are not trying their best. It simply means that the scores may not have increased over the year before. There has to be a better way to evaluate students.
