To facilitate interactions among students from different cohorts, several key program mechanisms are in place. Firstly, the new student welcoming event, attended by both faculty and Ph.D. students, helps to initiate connections. The Ph.D. Seminar, attended by all first and second-year students, as well as students from other years, further promotes cross-cohort engagement. Additionally, elective courses bring together students from various cohorts, offer another way for interaction. Graduate Assistantships offer opportunities for collaboration across different class years. Moreover, the Ph.D. Social Work Student Association (PSSWA) organizes meetings and social events, providing networking and interaction opportunities for students.
