High school is a term used in parts of the English-speaking world to describe institutions which provide all or part of secondary education, but not always the highest years of basic education, which can be called a "secondary school" or "secondary college" or other terms, depending on the nation or region (see below: Usage by country). The phrase "high school" is often incorporated into the name of the related institutions.

The term (as "high school") originated in Scotland, with the world's oldest being Edinburgh's Royal High School from 1505. The Royal High School 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. The precise stage of schooling provided by a high school differs from country to country, and may vary within the same jurisdiction. In all of New Zealand and Malaysia along with parts of Australia, Bangladesh and Canada, high school is synonymous with secondary school, and encompasses the entire secondary stage of education.

John J. Hardin (1 Oct 1753–circa May 1792) was a soldier, farmer, rancher, noted marksman and hunter. He was wounded fighting in Lord Dunmore's War; served as a Continental Army officer in the American Revolutionary War and as a Kentucky Co., Virginia militia commander in the Northwest Indian War. He was a member of the Methodist church and one of the first judges in the original Washington County, Virginia (later to become Washington County, KY). John Hardin was killed in an ambush while acting as a peace emissary (under the direction of the President, George Washington) to the Shawnee Indian people.

Born in Prince William County, Virginia (in an area that is now Fauquier County), John Hardin was the first son and fifth child of Martin Hardin (1716–1778), an owner of an "ordinary" (or roadhouse/bar) who was a member of the Virginia militia, and Lydia [nee Waters] Hardin (1721–1800). John Hardin married Jane Daviess, and together they had seven children, with future Kentucky senator, Martin D. Hardin, their youngest.
