In the high school years, formal Rhetoric is offered so that students may be trained in how to communicate clearly, thoroughly and persuasively in both speech and writing. Students are taught the four canons of Rhetoric:
- Invention: the developing of arguments through research or impromptu;
- Arrangement: arranging their arguments for strength of persuasion and following the six parts of a discourse (introduction, statement of facts, division, proof, refutation and conclusion);
- Style: adorning speech or writing for delight and clarity;
- Memory: thorough familiarity with their communication with clarity and proper adornment.
