Do highschool teachers cheat in school?
High school teachers are people. So, the real question is, do people cheat in school? The answer is, some people cheat sometimes, including teachers. As a high school teacher myself, I have heard of that happening. That said, most teachers don’t cheat because a) they have ethics, and b) they don’t have a reason to.
I am not sure what you mean by this question, but people in general will cheat. No one is perfect but if you mean cheat as in grade someone else harder than another then I would say yes but it is sub conscience. Someone who is liked by the teacher will receive higher marks than someone who is not liked, its just a fact of life but if you clear up your question i might be able to help a little more.
