Technically yes but see below -
Why is double depositing unethical?
It's deceitful. Students know they can only attend one college, so they are essentially lying when they notify more than one that they intend to enroll.
It's unfair to the college. If the practice continues, colleges may find they can't predict the size of the incoming class with any accuracy. They may take actions such as enlarging the waiting list or increasing deposit amounts (both of which will impact future applicants).
It's unfair to other applicants. The double depositor is taking up a spot that could go to another student, who will instead be put on a waiting list or turned down.
I've never done this (double depositing) mostly because I don't have that sort of money to throw around and I would take the time to analyze the choices and make the best decision and move on so that people don't have to be on a waitlist too long. HOWEVER I don't believe this practice is "unethical" at all. Consider this activity on the part of schools:
1. MPH degrees, especially in certain concentrations, are being awarded at a higher rate despite decreased jobs the past decade, this has been discussed in research articles that it is unfair for schools to do this though masters programs are money makers for schools and each school believes they should be entitled to a lot of students.
2. Schools make you pay a deposit as sometimes life gets in the way, people get in a car accident, they have a sudden death in the family, things happen . . . do schools return these deposits in these cases? It is a legitimate question about waiting to get a scholarship at a different school, paying two times as much at one school versus another school is a big deal financially.
3. Schools false advertise, one school consistently runs ads claiming they are the #5 public health school, but the fine print says among private public health schools, that drops their rank a lot. Also, rankings are biased for schools that get a lot of NIH grants and more important is what skills you get with an MPH and going to a school in the region you want to live in.
4. Some schools treat students
very poorly, the faculty couldn't care less about how students are treated and more emphasis is put on bringing in the new group of students than improving and updating the curriculum. Some schools might want there to be a "Public Health School Endangered Species Act" and for accepted applicants to pay a $1,000 fee to be a name on a list and to be put in prison if they don't come to their school, but it is important to respect student's rights to look for the best place where they can thrive not just serving the school's bottom line.
5. There is a reason why there is a deposit at all, it is because schools know that students change their mind, is it even ethical to have a deposit? To being paying part of the tuition at a school that you'll never attend? I understand library fines (paid my fair share!), I understand $20 or even $50 to hold your place, but hundreds and hundreds of dollars?? Schools must be making a lot of money off of collecting these "fees" just like banks that add on fees.
6. Many public health school over charge on the tuition, they're basically taking a mortgage out on your dream to make the world a better place through public health in order to pay for a lot of things not related to your education.
7. Holding two spots for a finite amount of time doesn't erase one of the spots, you can't attend two schools (or at least not easily!). So you aren't unethically destroying seats in a school, just prolonging the process.
8. What is the wording on the deposit? Isn't it just to hold your place as an accepted student? As there is a deposit that implies that people will change their minds, if I needed to give the library my credit card to pay late fines in the process of getting a library card, and if they make me sign something promising I'll return the books on time then it would like the system expects me to fail. If I miss the due date on a book . . . is this "unethical" and breaks the librarian's heart or something?
9. Why don't all schools announce their acceptances on the same day then? Say I get into a school that is good, and I send in a deposit planning to go to that school, but I get into a school I admired more that I never would have thought I would have gotten into . . . how. is it unethical to go to the more admired school?
10. Isn't the system of admissions deposits a sort inequity in that students with resources can pay to hold these positions while they search for other more financially feasible schools and scholarships? Obviously schools felt they had to financially compel students to go to their school or risk being penalized monetarily. School admissions are like used car salesman, they give out scholarships and discounts once they realize they can't get enough students with exorbitant prices, if they were acting more ethically they'd offer everybody a fair deal straight up in the beginning of the process and avoid late decisions, but that is the game.
NEVER have been to a used car dealer and negotiated a price, told him I'd think about it for a week (while looking at other options) and tell them my decision later only to be told that I have to pay $400 to "hold the car" right now and that I forfeit it if I ulitmately choose another car!
