The PhD is a program of independent, supervised research that is assessed solely on the basis of a thesis, sometimes including a creative work component, that is examined externally. The work presented for a PhD must be a substantial and original contribution to scholarship, demonstrating mastery of the subject of interest as well as an advance in that field of knowledge.<br><br>The PhD comprises an independent, supervised research project mutually agreed upon by a student, supervisor, head of school and the Board of the Graduate Research School. It may be undertaken in any school in the University. The PhD requires the development and implementation of a rigorous research plan, based on a comprehensive understanding of the relevant literature and the need for answers to questions posed in that literature or as the result of a new theory. The thesis demonstrates a student's ability to document and interpret results, formulate theories and discuss the results in light of the current literature to a high level of competence. Each student's PhD experience is different because each student undertakes a unique course tailored to their interests and needs. All students undertake research that is assessed in the form of a thesis. Students may also undertake taught courses, industry placements and other developmental activities. Many students choose to spend part of their candidature undertaking research interstate or overseas.
