I am saying that the system should fail open in their absence. "Students' achievement dropped 50 points!" makes for a really potent policy cudgel. "Students' learning dropped 50 points, +/- 40" is silly and meaningless. The former should never be available, unless the +/- is explicitly mentioned. This is similar to prescription medicines. We have a lot of prescription medicines that do great things, which no one is debating. But without a proper evaluation process, you have zero access to them. Test assessments should be similar in my opinion.
