Plan A vs. Plan B:
The vast majority of incoming Master's students are admitted to the Plan A Degree Program. In this option, the student is expected to write a thesis making an original contribution to the research field of a quality acceptable to a major, peer-reviewed scientific journal. A small number of students, primarily those without research funding and/or who have a full-time job commitment, are admitted to the Plan B Degree Program. This program requires the writing of a professional paper of a quality demonstrating a high level of scholarship. Occasionally, Plan B students transfer to Plan A if research funding becomes available. Only under very special circumstances is a Plan A student allowed to transfer to Plan B.
