Barring extenuating circumstances, each child shall have the opportunity to go on at least one field trip and/or overnight field trip per year. The trip should be appropriate to the age of the students and have clearly defined educational goals. All trips must receive final approval by the appropriate principal and the Head of School, who will consider the school time used, the relationship of the trip to instruction, the anticipated participation, assessment of risks, and the cost.
