In the Upper School program, students move from Grammar to Dialectic and Rhetoric. The Lower School aims to build a solid foundation of knowledge and skills across the academic disciplines. The Upper School strives to instill habits of sound, critical reasoning and cultivate eloquence in communication.

While Grammar stresses the accumulation of information and mastery of fundamentals, the Dialectic emphasizes the passage from information to knowledge, which requires logic and critical thinking. Students study formal logic during their middle school years in order to sharpen their analytic skills. Additionally, in each subject area they begin to learn the distinctive logic of the discipline: to think as historians, scientists, writers, etc.
