Grade inflation and questionable grading practices are two common grading problems. Grade inflation is defined as an increase in average grades assigned to students for the same level of achievement. It can be caused by institutional pressure to retain students, increased attention to personal issues, higher grades for better evaluations, and changing policies. Questionable practices include averaging scores, using zeros, and lowering grades for behavior. These practices can undermine the purpose of grading, which is to accurately describe student learning. To have appropriate grading, teachers should prioritize the most recent, comprehensive evidence related to important learning goals.
