Intersession is a one to two-week period in the spring in which the Upper School's normal routine is interrupted so that all students and faculty can participate in special projects. All Upper School students and faculty are required to participate each year. Intersession projects might involve community service, physical activity, arts activity, cultural or informational trips.

* Costs are not included in the tuition and range from $0 to more than $1,600. Students must participate in at least one Service Intersession during their enrollment.
