Ph.D. Preliminary Exam

The Preliminary Exam

The primary purpose of the preliminary examination is to determine if the student has acquired the specialized knowledge necessary for their proposed dissertation research.

The preliminary exam is part of the Graduate School Requirements for the Ph.D. Degree. For more details on University requirements, see the Graduate School's rules governing the exam.

The key regulations on the exam are:

  1. The preliminary exam is an oral exam in front of a committee of at least four professors.
  2. The chair of the committee should be the student's research advisor.
  3. The exam must be taken before the end of the student's third year.

    A student who has not passed the examination by this time must file with the Dean of the Graduate School a statement, approved by the Director of Graduate Studies, explaining the delay and setting a date for the examination. Except under unusual circumstances, extension will not be granted beyond the middle of the fourth year.

    A student must be registered during the term in which they takes the preliminary examination. In the summer a preliminary examination may be scheduled only between the opening and closing dates of the summer session. See the academic calendar.

  4. The committee is recommended by the student and their advisor to the DGS who appoints the committee. The DGS must submit the list of committee members on a committee approval form to the Graduate School. After the Graduate School approves the committee, there is a 60 day waiting period before the exam can take place!
    Students should NOT delay the start of the committee approval process: only a list of Professors is needed (not an exam date or time or syllabus!)
  5. Professors from other Universities can serve on prelim committees with the approval of the Graduate School.
  6. The student and advisor will write a syllabus to be covered in the exam. This outline must be approved by the members of the exam committee and the DGS. The student and the committee should agree upon a syllabus for both the major and minor topics. These must be sufficiently separated. The syllabus must be submitted to the Director of Graduate Studies for approval.
  7. Unless changes take place later, the committee for the preliminary exam will also be the committee for the PhD thesis defense.
  • Assessment of performance on the exam will be entered on an exam evaluation form by each committee member.

Satisfactory completion of the preliminary examination

This occurs when at least 3 of the 4 committee members, one of whom is the chair, cast an affirmative vote. (For a 5 member committee, at least 4 affirmative votes are required.) See the Graduate School Requirements for further information.
