there are definitely pros and cons to all of them
local leaders are closer to the people, but might not make a curriculum strong enough for students to succeed in other areas
states are a better option, but still would have different things taught than other states
the federal government would make a curriculum thats used nationwide, so everybody is educated on the same topic, but depending on what political party is in the gov, education could be skewed to make kids believe party beliefs.
personally I think either the states or the federal gov is the best choice to make decisions about what students learn and how they’re tested
