I was involved in K-12 math education for a few years and there's absolutely a pressure to make things easy for kids. When certain parents see Johnny scored poorly on a test, guess what they do? They start a conversation with the teacher and administration. Johnny needs to pass, or maybe even succeed, and it's the education that has to change around him. It creates more work. Teaching already isn't a traditional 9-5. Grading homework can consume hours outside of normal working time. Meanwhile, I can count on one hand how many times I needed to put in overtime at my office job. If the school has a tuition, then there's even more of a conflict of interest. I've had parents/admins imply that we might be losing a student due to poor grades.
