Reading through CC I have noticed that at least two schools: Boston University and, surprisingly, Cornell University offer some applicants who are denied admission as freshman guaranteed admission as sophomore transfers, The student must enroll at another college and maintain at least a 3.0 GPA and there may be other conditions.
This practice seems unfair both to the school the student attends freshman year and to the students themselves. For the freshman college it will lower their retention and graduation rates. But more importantly for the student it could make for a difficult freshman year. They will enter a college with one foot already out the door. They would be less likely to become involved in campus activities etc. And if they tell their dormmates/classmates that they will be transferring to a "better" school they may have difficulty making friends.
Also no one has posted about the financial aid aspect of such offers. Are they given a tentative financial aid package at the time they are given the guaranteed transfer option or do they have to apply for financial aid at the time they decide to take the school up on the transfer option? in the latter case transfer applicants tend to get less generous financial aid packages at many schools. Or maybe these guaranteed transfer options are only made to full or near full pay applicants?
