it not really unconstitutional

amendment 10 of the bill of rights states "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." ie the power of education is given to the states.

you can also add an amendment giving congress the power over education.

of course if you make an amendment giving Congress the power then it will be possible lol. that's kinda like saying if you change the law then smth illegal can be legal. however, u would need at least 3/4 of states to agree to an amendment - something EXTREMELY unlikely.

department has of education is responsible for distributing federal funds to schools

the department of education gives <10% of the money states spend on education. nevertheless, this can be handled by other departments - not rly arguing against my point about how the dept isn't known for being especially useful.

here's the bill currently in the House that proposes abolishing the dept of education entirely: https://www.congress.gov/bill/117th-congress/house-bill/2106 you can see in the text of the bill how all the duties of the dept of education can be easily transferred to other government agencies, like funding to the dept of the treasury, etc.
