This paper investigates the existence of GCED principles in Omani Basic Education schools' visions and missions. A qualitative exploratory collective case study research design was used by analysing 50 schools' vision and mission statements for the existence of five GCED principles: peace and conflict, human rights, identity and diversity, environment concerns, commitment to social justice, democracy and equity. The results revealed the varying existence of GCED principles, with commitment to social justice, democracy and equity principle being the most evident principles and the environment concerns principle the least evident in the dataset. For enabling schools to produce global citizens, schools need a revision of their visions and missions for better inclusion of GCED principles.
