Master-level postgraduate professional development (PPD) programs have grown rapidly in many parts of the world. Being able to complete written assignments successfully is a significant concern for students pursuing PPD studies. Yet the nature of written assignments in such programs has been under-researched. This paper reports a study conducted in the context of a Master of Education (MEd) program in an English-medium university in Hong Kong. The study addressed the research question "How do MEd written assignments prompt students to engage with academia and the professional world?" Analyses of the documentary data, comprising a collection of written assignment prompts featuring 132 tasks, revealed three categories of assignments: oriented to the professional world, oriented to academia, and connecting academia and the professional world, with the last category being the largest share (75%). The paper illustrates these categories of assignments and considers implications of the study for pedagogy and future research.
