The function without the apparatus. Everyday, all across the country - we pay teachers to teach and assess their students. Those assessment results aren’t trustable for benchmarking and ranking students, so we have standardized testing. Obviously, yes - one intention of this concept is that it serves the same function as standardized testing, but it does so while eliding the externalities of cost and single, high stakes exams by allowing classroom assessment - made and proctored by the instructors during their standard lessons - to become trustable.
