"With Great Power Comes Great Responsibility"
Stan Lee, 1962
They were out of high school, but never went to college, they got jobs as feds and then the series was canceled.
I don't remember a mention of school in the books, they seem to be perpetually out on summer break, just like they are perpetually 16 and 17.
Actually in the books Joe was 17 and Frank was 18.
