The Aquinas Chapter at Brother Rice High School is directly affiliated with the National Honor Society, one of the most prominent nation-wide organizations for high school students. Like the organization at large, the chapter is founded upon the pillars of character, scholarship, leadership, and service, and students embracing these ideals are encouraged to join. Members show their commitment to these pillars by keeping the standard of excellence in and out of the class and by facilitating various activities within the school community. Members of the Aquinas Chapter are ambassadors of the school and seek to perform service at Brother Rice, and in the community whenever possible. Membership is limited to juniors and seniors.
