Where are the Department Heads?

You raise an interesting point - how could it be that one teacher gives one test in a marking period and the majority of the department is giving 4 or 5 tests?

There are Department Chair-people for each subject who make hefty salaries who should be overseeing that this sort of thing isn't happening.

You're absolutely right about all people not performing at their highest level when there are no consequences for their actions.

Teachers are given a lot of freedom here - but there should be basic non-negotiable requirements for every grade and subject.
