The department does not have a minimum score requirement. The GRE will be taken into consideration when the review committee assesses your ability to succeed in the graduate program. It is an important component of your application. Your entire application will be taken into consideration. Therefore, if your GRE scores are not the best, but the rest of your application is strong (excellent letters of recommendation, good grades, and your application is otherwise strong), then a less than perfect GRE score may not necessarily keep you from being admitted.
You can find admission statistics on our website, for those offered admission for 2011.
