School Notes
- At Marianapolis, students are involved in activities across disciplines and are constantly challenging themselves to set new goals and break molds. Our curriculum encourages students to think creatively and to articulate ideas effectively. Learning by doing is a hallmark of a Marianapolis education through project-based learning platforms such as Centers of Excellence, LEAP Week, and Experiential Learning. The Centers of Excellence allows students to pursue a specialized diploma in a specific academic track that includes an internship, and culminates in a yearlong capstone independent study project. LEAP Week (Live. Experience. Advance. Prepare.) is a one-week mini-term course requirement in May during which groups of students and faculty explore a specific topic, project, or adventure. These signature programs have them applying what they are learning in the classroom to real world situations on and off campus as well as helping our students stand out within the college admission process. With over 40 clubs and organizations, as well as a plethora of athletic opportunities, Marianapolis graduates are confident, conscientious young adults ready to lead.
