The History Department's approach to the instruction and study of history is predicated on the foundation that Saint Andrew's School is a strong college preparatory institution.

The Episcopal School Foundation chartered Saint Andrew's School in 1961. The Rev. Hunter Wyatt-Brown, Jr. (Headmaster from 1962-63) and Eugene Curtis, Jr. (Headmaster from 1964-71) led the effort to secure the land and funds necessary to build the school. Many in the community came forward to support the project, most notably Lucy and Alexander Henderson, who gave the majority of the funds needed to start the school.

Founded by people of Scottish heritage, Saint Andrew's School was named for the patron saint of Scotland, Saint Andrew. Go Scots! is a familiar chant at athletic events lead by Scotty, the school's new mascot.

This land was significantly removed from the small population base of Boca Raton in the early 1960's. The first chapel services were held outdoors in the "Chickee Chapel" built by Seminole Indians, framed from native trees with palmetto fronds for a roof. Snakes and alligators were a frequent nuisance on campus.

Attractive and safe residential neighborhoods have now developed around the large impressive campus, which showcases much of the old-growth native pine and tropical foliage. While it opened as a boarding school for boys, today it is a co-educational day and boarding school with 1288 students in Junior Kindergarten through Grade 12. The Lower School opened in 2000.
