(22)A big difference between public and private in American higher education involves money. Public colleges and universities are less expensive because they get money from the states that started them to educate local citizens. As a result, out-of-state and international students usually pay more than state residents, at least in the first year. The University of Oregon, located in Eugene, is one of the public universities. The cost for undergraduates this year is $ 6 000 for state residents. (23)Housing is an additional $ 8 000. Non-residents pay the same for housing, but almost $20 000 for tuition and fees. Let’s see how these numbers compare to a private college in Oregon. Lewis & Clark College in Portland has 4 000 students, compared to 20 000 at the University of Oregon. (23)Housing costs $ 800 more than at the state school. But the big difference is tuition. The published price at Lewis & Clark is almost $ 34 000. (24) Yet Lewis & Clark is one of the few American colleges that offer financial aid to international students. Each year it awards financial aid to 20 students from other countries. (25) That would make Lewis & Clark cheaper for international students than the University of Oregon. But, of course, prices alone do not say anything about the quality of a school or the value of an education.
