As a private school, OUS has two sources of revenue. The first is tuition and fees, which fund educational programming, and the second is charitable gifts obtained through fundraising. At OUS, tuition and fees cover about 80% of the actual cost of educating a student. Tuition is set at this level to make OUS education an affordable option for more families. OUS relies on donations to fund other needs that would not be possible from tuition revenue alone.
