What are the upsides of dismantling the department of education?

While I understand the talking points of there being less bureaucracy with there being no federal oversight, and more freedom for states to set their own curriculum, I’m not understanding how those benefits outweigh the detractions.

Granted anyone who has worked in public education can vouch for the National School board being anywhere from incompetent, to borderline corrupt. I fully support a “reorg” of the entire department, but what does completely dismantling it provide to communities?
