The Middle School curriculum expands the academic foundation established in the Lower School and builds toward the more rigorous demands of the Upper School. Students are required to take core subjects in English, mathematics, science, Spanish, and history, and they are also given the opportunity to explore interests in the arts. All classes focus on the ability to articulate thoughts in oral and written work as well as develop critical thinking skills. In the eighth grade, students are required to do an exhibition of mastery as a culminating event reflecting the student's readiness to move on to high school. The exhibition of mastery is a major investigative project involving research, interviews, surveys, data collection, a paper, and a presentation.
