ED students can always get out of an ED commitment based on financial need. And ED is no more a binding, legally enforceable commitment than any other admission. It's only the social "contract" of treating ED as a desired and acceptable admissions program, based on mutuality of benefits for both student and school, that enables it to work. Unlike ED, where a student increases the likelihood of admission in return for an early commitment, at WCU, the students are treated no differently than RD but the department demands that they make a commitment like ED. It is entirely unilateral in benefit.
