However, Teachers are expected to fulfill the role of replacement teacher and/or support teacher in a manner that is exemplary in all areas.

Teachers, at each grade level, report to the Head of Upper School who is accountable for the successful outcomes of all activities within a particular grade level. This is a one (1) year contract. This position will commence late August 2026.
