From ninth through twelfth grade, students in the Rhetoric stage move from receiving and discussing information, to learning to defend their own ideas. The history cycle from ancients to the modern day is repeated, but this time students are taught how to develop a theses, research properly and present information to their teachers and peers. They learn to how to write and speak well.

Students can choose to continue with Latin or study a modern language. Science topics include biology, chemistry and physics as well as computer science. All high school students receive ACT preparatory classes, and higher level math including trigonometry and calculus are offered. All graduating seniors must complete a Senior Project – a year long, multi-disciplinary project that includes a written component, a multimedia project, and a presentation to faculty, students and parents.
