About High School
High School refers to grades 9-12 in the United States. Its name is believed to originate from 14th-century Scotland, where 'high school' referred to the Royal High School of Edinburgh and was used as a model for the first public high school in the United States, the English High School founded in Boston, Massachusetts, in 1821.
