Answer:
Personally, I believe school newspapers wouldn't be considered as being under the first amendment, for the simple fact that kids are minorities, and aren't seen as capable of making legal decisions in the eye of the law. If young people aren't even allowed to vote for their own president, until they're 18 or so. Then a school newspaper wouldn't be counted under the first amendment either, because simply-put, if the youth's views are easily brushed aside in regular politics, what makes a school's newspaper, written by students for students, any more valid?
This isn't the only reason why school newspapers wouldn't count, though. You see, the government and the school board are seperate entities. Meaning, while the government can control and decide curriculum for schools to follow, the rest of the country's laws don't necessarily apply to the students in a school setting, so freedom of the press wouldn't apply to them either. This intern, would mean that a school newspaper isn't a thing that would be protected under the first amendment. Does this mean I agree with the government's reasoning, for not allowing school newspapers protection under the first amendment? Well, yes, becasue school newspapers are strictly a school thing, for students, and doesn't translate into the real world let alone politics.
