Student abuse by their teacher is not as prevalent as sometimes publicized. However, when it does happen parents should be quick to document instances of said abuse and act quickly. One of the most difficult types of abuse to prove is unfair grading which is one of the most spiteful ways an educator can mistreat their pupils.
An instructor who “has it in” for a student they don’t like can give them a score of 60 on subjective written work whereas a grade of 85 might be given to the teacher’s pet for the same effort! This insidious and difficult to detect practice is a challenge for a parent to protest to principal or the school board at a higher level.
Legal expert Kristen Johnson writes extensively about how to combat bully teachers and take legal action in these instances of preferential grading.
