College Heads of Department (HoDs) are increasingly expected to perform more curriculum-leadership tasks, maintaining and advancing the department curriculum, especially in developing countries. However, in practice, HoDs are reported to pay little attention to this aspect of their job due to several factors--one of which is a lack of professional support to play this role. This case study investigated how four HoDs of a community college perceived and enacted curriculum leadership during a curriculum-development project after receiving relevant training and assistance. The findings showed that the HoDs valued the relevance and usefulness of the professional support received, which made them realize the significance of their role as curriculum leaders. The findings also indicate that the ways the HoDs enacted the curriculum-leadership tasks and the challenges they encountered varied based on several factors. The conclusion drawn is that the support HoDs need and the challenges they encounter in assuming active curriculum leadership suggest their need for three professional competencies and the need for supportive organizational structures.
