<p>I need to withdraw some applications because I was accepted ED I know name, birth date, and school are helpful things on the letter, but I was wondering if I had to explain the reason for my withdrawal.. Is giving a reason following etiquette, or just something nice to do?</p>
<p>Along with your personal information state that you appreciate their consideration in the application process but that you have decided to attend another school. Keep it simple and polite. Don't say, for example - 'I'm going to go to School X because they have a better B school than you.' Leave the door open to transfers with schools you are turning down just in case the "fit" with your ED school doesn't work out.</p>
