Qualifying Examinations

The Qualifying Exam (QE) is a literature-based “general” exam that tests a student's ability to read primary research articles, synthesize information, and apply critical thinking and analysis to important biological questions across disciplines.  Typically, examinations take place in January/February of year 2.


  • Gain facility with critical analysis of the primary literature
  • Master the wide range of approaches, techniques, and model systems applicable to PMB research

Paper Selection:

  • PMB faculty submit primary research articles they feel best represents “the best in their field” for the previous twelve months.
  • Submissions will be due August 7, to ensure that selected papers can be given to 2nd year students by August 15, prior to the start of classes.
  • Program directors select articles that represent the range of research in PMB.
  • Students read and analyze the group of selected papers as part of Bio5723.


The fall semester prior to the QE, 2nd year students enroll in Bio5723: Seminar Plant and Microbial Biosciences

  • 2 credit course. Counts towards PMB’s journal club requirement
  • Students will be in charge of divvying up the papers and presenting them such that each student gets a fair share of the burden
  • The presenting student will write a 1-page synopsis on each paper to hand out to the class prior to their presentation.

Committee Selection:

  • 3 faculty members will be assigned to committees based on availability and balanced composition. Exam chairs will be selected from the PMB steering committee
  • Once the examination committee is selected, faculty will send their paper selections to the committee chair to avoid overlap.
  • Students will not be told beforehand which faculty are on their exam

Exam Format:

  • During the 90-minute exam, each of 3 faculty examiners select 2 papers (6 total) to question students on. Once the first question has been asked, the floor is open to questions from all faculty examiners. A soft 15 minute limit per paper aims to ensure that the exam proceeds in a timely manner.
  • The exam chair will have pdfs of all the papers available to put up on screen to help the student (and the examiners) get their bearings. 
  • Faculty are encouraged to test critical thinking and AVOID questions focusing on memorization!
  • Students will not be told their status until after the steering committee has met.


  • At the end of the exam, faculty score performance on a 1 to 5 scale with 5 being high. Students will need an average of 2.5 or higher to pass

To ensure continuity across committees, the ultimate decision on pass/fail is left up to the steering committee which meets after all exams are completed.


•    Pass.

•    Fail.  If a student fails, they will have three weeks to schedule a retake.  The reading list will not change, but papers used in the first round will be eliminated from the pool.  The chair of the first exam committee will serve on (but not chair) the retake exam committee.

  • Note that a failing outcome upon retaking the exam will result in automatic dismissal from the program.
  • If the student does not wish to retake the exam, it is possible to graduate with a terminal Master’s degree pending submission and defense of a Master’s Thesis.
