General and final examinations

The General Examination is given in two parts:

  • Part I is a written comprehensive examination based on the course content of STAT 6202 Mathematical Statistics II, STAT 6213 Intermediate Probability and Stochastic Processes (administered by faculty of the Department of Statistics), and PUBH 6266 Biostatistical Methods (administered by the faculty of the Department of Epidemiology and Biostatistics). Students are expected to take the comprehensive examination within 24 months from the date of enrollment in the program. In addition, students are required to make up any deficiencies prior to taking the examination, e.g., by enrolling in appropriate master's-level courses as needed. A student who fails to pass the comprehensive examination may, with the approval of the faculty, repeat the examination the following year. Failure on the second attempt will result in termination from the Ph.D. program.
  • Part II, the research proposal, consists of an oral examination based on a written dissertation research proposal. As soon as feasible after successful completion of the comprehensive exam, students are encouraged to identify a dissertation advisor and a topic of research. The written dissertation proposal is then submitted to the student's Dissertation Research Committee, and the student will make an oral presentation of his or her proposal to the Committee. The Committee will determine the student's readiness to pursue and successfully complete the proposed research, in addition to the appropriateness of the specific problem for dissertation-level research.

Upon successful completion of the required coursework and both parts of the General Examination, the candidate will generally be recommended to the Associate Dean for Graduate Affairs of The Columbian College of Arts and Sciences (CCAS) for promotion to Ph.D. Candidacy: the dissertation research. A candidate must file an approved dissertation research plan with the CCAS before being admitted to Ph.D. Candidacy. Prior to completion of the General Examination, a student may register for at most 6 credits of BIOS 8999 Dissertation Research.

Consult with the biostatistics program director or academic advisor for the dissertation guidelines.

Professional enhancement requirement: 8 hours

Professional enhancement activities supplement the academic curriculum and help prepare students to participate actively in the professional community. They enhance practical knowledge and awareness of public health issues – either in general or in a student’s specific area of study.

Students can fulfill this requirement by attending workshops, seminars, or other relevant professional meetings, which are often held at SPH and in the metropolitan Washington, DC area. Examples of conference sponsors include the National Academy for State Health Policy, the Pan American Health Organization, the American Public Health Association, the American College of Healthcare Executives, the Area Health Education Center, the American College of Sports Medicine, and the National Athletic Trainer’s Association. Opportunities for professional enhancement are regularly publicized via the SPH Listserv and through the department or the biostatistics academic advisor.

Students must submit documentation of professional enhancement activities to the biostatistics academic advisor, which includes a prior approval, a description of the program agenda, and proof of attendance before applying for graduation.
