All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of six terms as a full-time PRS student or twelve terms as a part-time PRS student, you will be expected to apply for transfer of status from Probationer Research Student to DPhil status. This application is normally made by the fourth term for full-time students and by the eighth term for part-time students.
A successful transfer of status from PRS to DPhil status will require a report that will consist of an introductory part that could become the introduction to the thesis, one rather well-worked analysis of preliminary data representing roughly the equivalent of one thesis chapter, and a plan for the other chapters in the thesis including a detailed timetable. Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status to show that your work continues to be on track. This will need to done within nine terms of admission for full-time students and eighteen terms of admission for part-time students.
Both milestones normally involve an interview with two assessors (other than your supervisor) and therefore provide important experience for the final oral examination.
Full-time students will be expected to submit a substantial thesis of up to 50,000 words after three or, at most, four years from the date of admission. If you are studying part-time, you be required to submit your thesis after six or, at most, eight years from the date of admission. To be successfully awarded a DPhil in Biology you will need to defend your thesis in a viva voce examination in front of two appointed examiners.
