My high school (NY State) required a year of American History and a year of World History. I believe there were state-required "Regents" exams for both if you wanted to graduate with a "Regents Diploma". We also had lots of American History in 8th grade.
College did not require any American history (I was not a history major, so don't know if any was required for them.) All students were required to take "Humanities 101) ... which was actually a history of world religions; one semester packed with volumes of information. Also required at least one year of English (may have been two?)
