As a condition for doctoral candidacy, all students must pass a Preliminary Examination (Prelim). The exam consists of two parts, the written research proposal and an oral defense before the members of a student’s Advisory Committee<\/a>. Students must complete both components of the preliminary exam before the first day of class during their third year in the Ph.D. program. Both parts of the doctoral preliminary exam are detailed below.<\/p>\n\n\n\n

Written Preliminary Examination: Research Proposal <\/strong><\/h2>\n\n\n\n

The preliminary examination process begins with the written component – a research proposal – at the end of a student’s second year in the program. <\/p>\n\n\n\n

Doctoral students must write and submit two or more pre-proposals to their advisory committee that include a background, significance statement and list of specific research aims. The written proposal should focus on student’s doctoral research or a closely related topic. <\/strong>The advisory committee will then have two weeks to select one of the pre-proposals to be developed into a proposal; changes in aims can be made by the committee at this time.<\/p>\n\n\n\n

Next, students must prepare their written research proposal independently, following the National Institutes of Health (NIH) formatting guide<\/a>. Proposals are expected to be 7 single-spaced pages in length, including figures and tables (but not references). <\/p>\n\n\n\n

See our formatting guidelines for the written proposal<\/a>.<\/strong><\/p>\n\n\n\n

At least six weeks before their oral defense date, students must submit their proposal to their advisory committee. The committee will have two weeks to evaluate the proposal, at which time they will provide a written evaluation of the proposal to the student, to other members of the advisory committee and to the DGP. <\/p>\n\n\n\n
