The Cooper Union, which has traditionally awarded full scholarships to all students but which last year started charging tuition to graduate students, is again considering tuition for undergraduates, The New York Times reported. The move to start charging graduate students was designed to keep undergraduate education free, but officials at Cooper Union said that financial challenges may make it impossible to remain tuition-free. Many student and alumni critics, however, say that an important tradition is at risk, and some question spending priorities by administrators.
