After successful completion of the qualifying exam, the presentation and defense of the written research proposal at the end of year three, DPPD candidates enroll in the capstone course. There is peer collaboration and feedback during the year-long research and writing process. The capstone instructor serves as the second member of all DPPD professional dissertation committees. Please see our “DPPD Professional Dissertations” link on the homepage for examples of projects-of-practice completed by former USC Price Professional Doctorate students.
