Teachers paid based on student performance

I do not believe that teachers should be paid based upon whether or not their students are performing well or not. There are a few reasons for this. One reason is because some students simply do not want to be in school so they will not participate or listen so they will not perform very well no matter how hard a teacher tries. Another reason is because some areas may perform better than others. For instance, one school may have lower income families that go there and statistics show that they perform lower. Another school, perhaps with higher income may perform better. These schools may be in the same district so it is not fair for teachers to have to be paid differently based on student performance. Also, some students may be behind from previous teachers so they will not perform as well since they are not caught up to the material that you should be covering at that grade level.
