Prospective students are encouraged to submit an inquiry below for the PhD Health Sciences Program so that they can be contacted by an admissions advisor. Prospective applicants should have earned a 3.0 GPA minimum. Applications that do not meet our requirements will be reviewed on a case by case basis.

You are required to take at least five research methods courses and two required theory courses in the field of health sciences. These courses will provide the foundation for your pursuit in specialized concentrations. All courses are four semester unit courses. The last course taken prior to the dissertation series is the required DHS699, Dissertation Seminar.

Trident accepts eligible doctoral level credits from regionally accredited doctoral granting institutions provided the transferred course meets the same content standards as the Trident course.*

Note: Students may be required to purchase statistical software for the quantitative research courses and dissertation research.

*Transfer credit is evaluated on an individual basis. Not all credits are eligible for transfer. See the University Catalog for transfer credit policies.

You may choose one of the concentrations offered in the Ph.D. Health Sciences program. Twelve elective credit units are needed to fulfill the concentration requirements:

  • Global Health - This concentration focuses on global health and will explore how globalization impacts determinants of health and disease. Courses include Current Issues in Global Health Research, Global Epidemiology, Introduction to Health Equity, and Special Topics in Health Science and Public Health.
  • Health Policy and Administration - This concentration prepares leaders in health policy and administration through evaluation, development, analysis, and implementation of health and health policies. Courses include Advanced Leadership, Health Care Law, Regulation and Ethics, Current Issues in Health Administration, Seminar in Strategic Planning for Health Sciences, and Special Topics in Health Science and Public Health.

The comprehensive exam (or qualifying exam) includes a written and an oral portion. You will be examined on your understanding of theory, research methods, and statistical concepts related to the research process in your area. The comprehensive exam is scheduled during your first course in the dissertation phase of the program (DHS699).

A committee of two faculty members will review the written exam and send their recommendations to the Program Director on whether they think you are ready to proceed to the oral exam. If approved to proceed, you will sit for the oral exam within a week. During the oral examination you will defend the written portion and answer any pertinent questions from faculty members. One of the key objectives of the written and oral qualifying examination is to assess the ability and preparedness of the student to successfully complete their research-based dissertation.

If you fail the first attempt you will be given another chance to pass the qualifying exam. Failure in the second attempt will lead to disqualification from the program.

A dissertation committee and dissertation chairperson will be established for you. Each committee will consist of three faculty members with one serving as chair of the committee. One member of the committee or the chairperson must be external to Trident and at least one of the members are considered as a subject matter expert in the area of your dissertation research. The chairperson and the committee will be responsible for guiding you during the dissertation process.

You will show a synthesis of your doctoral study, knowledge and scholarship with a significant quantitative research project that contributes to general principles of knowledge in the field(s) potentially affected by the research. Furthermore, doctoral students may use qualitative research methods for their dissertation research provided they have a strong background in qualitative research. Following the completion of the course work including the Dissertation Proposal Seminar (DHS 699), you will work on the dissertation and register insubsequent sessions in the dissertation series (DHS 700, DHS 701, and DHS 702), and dissertation continuation courses (DHS 703 and above).

Pursuant to Federal law and regulations, Institutional Review Board (IRB) review and approval is required for research involving human subjects. Accordingly, prior to the student conducting research involving human subjects, including the collecting and analyzing of data, the proposed study must be reviewed and approved by the Trident IRB.

You will be required to complete 11 core courses (44 credits) and 3 elective courses within the chosen concentration (12 credits) for a total of 56 credits. Also, you must successfully complete both the oral and written comprehensive exam and complete the dissertation seminar/prospectus. Lastly, you will need to successfully defend the dissertation proposal and Ph.D. dissertation.
