Ca ed code 49066 says teachers decide grades. To what extent can schools or districts make rules that teachers must follow when they determine grades? Students adding a class halfway thru the semester, not having had the class previously sparked a conversation where admin said the new student should not have to make up missed work. Also on topic would be schools requiring a teacher to accept late work 2-3 months late, or other rules the teacher may disagree with. Aren't all these contrary to Ca ed code, the teacher decides?
