In the US, schools are not governed on a federal level. They aren’t even governed at the State or City level. They are governed by districts. I have seen some as large as an entire county with many cities in it (Polk county Florida is run this way) But I’ve also seen single town broken up into 9 different school districts (Indianapolis is run this way)
The reason this is important is that except for a very few exceptions – like certain guidelines a school must follow to be eligible for some extra funding, the districts run the show. If you live in Indianapolis in certain areas, what may be possible and legal for one kid who lives two blocks away from you may not be legal for you to do. You need to ask your school guidance councilor about this.
Depending on the rules and local laws, you MAY be able to get your parents to “home school” you and instead of being taught in school, you could just take the GED and graduate on your own. But some places make sure you can’t do this until you’re legally old enough to be a senior.
I do know one kid who did this – he had his parents “home school” him, but all they really did was allow him to take the GED when he was 16. Then he enrolled for college with summers and stuff he managed to get his BS at 19 while running his own business, which now he makes more money than his parents. He’s the only kid I know who wanted to drop out of school because it was slowing him down.
