A review of school curricula approaches to citizenship formation in a sub-Saharan African education context reveals such practice is still largely focused on a traditional social studies approach. This approach to citizenship development may be limiting in terms of potential to foster students' civic competencies for addressing social injustice associated with the impacts of globalization that impinge on local realities. Drawing on a critical global citizenship education (GCE) framework and GCE core conceptual dimensions developed by UNESCO, this study assessed the critical dimensions of the social studies curriculum for secondary education in one sub-Saharan African country. Through interviews with teachers, focus groups with students and a review of the social studies teaching syllabus, the study revealed limitations in both content and the pedagogical approach to the delivery of Ghana's current social studies curriculum for senior high schools.
