All applications and supplemental materials for any Biden School graduate program must be submitted through the University of Delaware's online graduate application.
You should have no need to send any items by mail when applying. Self-managing your own application in this way is possible because there are designated areas within the application to upload each required document.
Details about the application and documents that you will need to include are available on the Application Materials page.
If you have any technical concerns regarding use of the online application, please email firstname.lastname@example.org for assistance.
