This research employs a qualitative methodology to investigate Knowledge Management (KM) in the department of educational administration at a Saudi university. The research seeks to establish an understanding of KM, including its implementation and challenges. The findings from the participants are grouped into three major themes, each of which contains a number of sub-themes: (1) Understanding KM; (2) applying KM; and (3) the challenges of applying KM. The study is divided according to the participants' understanding of KM into five sub-themes: (1) the process of knowledge creation, socialisation, externalisation, combination and internalisation; (2) sharing tacit knowledge; (3) finding data electronically; (4) transferring tacit knowledge to explicit knowledge; and (5) sharing information. The results reveal the majority of interviewees view the implementation of KM as straightforward in the area of research and weak in the area of administration. All the interviewees stated that the main challenges when implementing KM in their department relate to issues of administration and culture.
