This is what I found in the Chatham website:
A baccalaureate degree from an accredited college or university
Cumulative prerequisite course grade point average (GPA) of 3.0 or better on a 4.0 scale; grades below a "C" are not acceptable in prerequisite courses
Overall undergraduate GPA of 3.0 or better on a 4.0 scale
On-campus writing sample and interview
Completed application for admission, including:
Official transcripts from all college and universities attended
Its weird that they put that on the requirement page, if they don't take that in consideration.
