Department of Education is a redundant beurocracy. Education is mostly funded and administered at the state level.
So you're saying we should have 50, 100, 200 different standards? Can you name another top 20 country in education that doesn't do it at the top? What you suggest sounds like a cluster fuck.
Considering the 'standard' that currently exists it might be better if there were 50 different standards. Maybe at least a few of them will get it right if there's a little competition between the states and we end up having some students worth their weight in gold.
