The reason Teen Challenge can operate at such low cost is the donor-supported model. Churches, individuals, and foundations fund a significant portion of the operating budget. Students also contribute through work therapy, cooking, cleaning, landscaping, maintenance, which keeps overhead low and teaches real-world responsibility at the same time.
