The Activity co-curricular program exists in order to enrich the Upper School whole student experience. Activity accomplishes this goal by providing opportunities for student and faculty experimentation, innovation, and leadership. Activities enable the sharing of expertise outside of a faculty member's or a student's normal academic arena, and they frequently benefit the school community at large. Broader student-faculty-community bonds often result. Departments may also use Activities as a way of expanding their offerings in ways that enhance the overall curricular program.
Unlike the academic calendar, Activity is scheduled into three, 10 or 11 week trimesters:
- Fall: 1st day of school through Winter Break
- Winter: Winter Break through Spring Break
- Spring: Spring Break through last day of school
Freshmen are required to participate in an activity all three trimesters; Sophomores are required to participate in an activity two trimesters; Juniors are required to participate in an activity one trimester. Seniors are encouraged, but not required, to participate.
Students enrolled in an academic course during the activity period will have the activity requirement waived for the semester of enrollment upon the successful completion (passing grade) of the academic course.
Satisfactory participation in the service learning program. (See full program description here.)
Satisfactory involvement in full- or half-day Winterim courses. (See full program description here.)
Successful completion of the College Decisions program in Eleventh Grade.
