Yeah, these are very good questions. It's easy to pick an arbitrary metric that seems like it would measure the right thing, but doesn't.
I usually try to stick to the specific phrasing - what is the test that measures your definition of success, such that if the test passes, success is definitely going up, and if the test fails, success is definitely going down?
Even before that step, part of the problem is that we have to have a definition of success before we can determine how to measure it. Ask people what the goal of the education system is, and you'll get many different responses.
