Doctoral Preliminary Oral Examination
The Ph.D. preliminary evaluation process is based on an oral examination and a letter of support from a Major Professor if the result of the oral examination is intermediate. Please refer to the Ph.D. Degree Requirements for a detailed description of the doctoral preliminary evaluation process.
Schedule and Application
Each preliminary evaluation period takes place during the Winter quarter. If you intend to take the oral examination, please download and complete the application form for preliminary evaluation and submit it to the graduate coordinator by the third week of November. At the same time, please a copy of your Winter Quarter schedule in order to help us minimize conflicts when scheduling exams. Please note that, as students taking the exam, you should not discuss the prelim problems with the examiners before or after the exams. Specific dates and times will be announced later once we complete the signup process.
The oral Examination will be offered in the six areas listed below. Students are required to take the examination in at least two and no more than three areas. Scores of two areas leading to the best outcome will be used. One of these two areas should be a research area of their Major Professor.
