The ATPS network functions through National Chapters in 30 countries (27 African and 3 Diaspora chapters). The National Chapters operate under National Coordinators who provide intellectual and administrative leadership at country level.
Each National Chapter has a strategic plan that outlines priority areas of research in their various countries. These identified priority areas guide the research efforts of ATPS. Other statutory functions of the National Chapters are specified in the Memorandum of Understanding between the ATPS and its national chapters.
