Our House System splits the Upper School (grades 7-12) into six Houses, each of which contains students from all Upper School grades. The purpose of the Houses is to provide for a widely dispersed student government, with leadership and ambassadorship opportunities for those who seek them out. With their Houses, students plan and execute school events, foster mentoring relationships between various grades, and develop unique traditions. Each House is named after a famous Roman from the republican era: Lucius Junius Brutus, Publius Valerius Publicola, Lucius Quinctius Cincinnatus, Marcus Furius Camillus, Publius Cornelius Scipio Africanus, and Marcus Tullius Cicero.
Houses compete for points in three Sentinel Games throughout the year and in the Campus Martius at the end of the year. Students also earn points for academic and character awards throughout the year.
When students graduate, they will have had up to seven years of planning and executive experience. If and when they choose to attend college, they will have the practical knowledge of how to begin clubs and associations, which is one of the core features of strong citizenship. The House System, then, is an education in civics because of the habits it encourages and forms.
