PGA103U

PGA103U is typically an introductory module offered in academic programs focused on public administration or governance. It provides foundational knowledge and understanding of public governance principles, structures, and processes. The course usually covers key concepts such as public policy development, the role of government institutions, public sector management, and the interaction between government and citizens. Students are introduced to the frameworks and tools used in managing public resources and services effectively and ethically.
The course might also explore contemporary challenges in public governance, including issues of accountability, transparency, and the impact of technology on public service delivery. Through lectures, readings, and case studies, students gain insights into the complexities of governance and the skills needed to address public sector challenges.
Upon completion, students should have a clear understanding of the basic principles of public administration and the various factors influencing governance outcomes. This course serves as a foundation for more advanced studies in public administration or related fields.
