tests
Hello. I'm not sure about the rules regarding the Terra Novas specifically, but generally teachers are not supposed to look at the standardized tests their students are taking. In my state, tests have little shapes on each page so that the teachers can circulate around the room making sure that every student is working in the correct section of the test without the teacher actually having to look at the test questions themselves (for ex., suppose every book and answer sheet in the math section should have a circle on it- the teachers just glance to check that there is a circle on everybody's pages, without ever looking at a single math problem). When we gave the Terra Novas, we followed the same idea- that we can't look at the questions. The exception is special ed. teachers, because we are allowed to read the questions to the students. But we are never allowed to discuss what we've seen (with colleagues or with students) after the test is over. And then we're supposed to somehow wipe our memories clear and not remember anything when planning lessons for the next year.

That's the weird part, like you've noticed!
