The University needs to know what learning and development has been achieved during your studies. Since the training does not rely solely on taught modules, you are required to record your learning and experiences and to identify what you have learned through reflection. Because of this, the University regulations for the PhD state:-
“In the case of a candidate for the Degree of PhD, PhD with Integrated Studies, MD, DDSc, EngD or EdD a candidate may not be permitted to transfer to that status from candidacy for a Master’s degree, (in the case of a candidate commencing the programme of study and research before 1 August 2012), or to pass the Confirmation Review (in the case of a candidate commencing the programme of study and research on or after 1 August 2012), unless the candidate has presented a portfolio demonstrating that they have undertaken the agreed programme of training and skills development and have achieved an appropriate level of competency as agreed by the supervisory team."
