This research paper presents the principals’ practices in delegating responsibility to teachers in public secondary schools in Kenya. A random sample of 20 secondary schools was used where 120 teachers filled questionnaires, and 20 principals from the selected schools were interviwed. Both the questionnaire and interview guide were designed based on six research questions. The data were analyzed using both quantitative and qualitative methodology. The study revealed that responsibilities related to financial decisions were not delegated. Teachers needed to consult before making any decisions on delegated responsibilities. There was little preparation of teachers for delegated responsibility; had limited opportunity to attend seminars and staff development programmes; little support was given to them, and had little or no guidance from the principals. Lack of finances, inadequate training, understaffing, and lack of cooperation among the teachers constrained the process of delegation. It is suggested, among other recommendations, that schools should be adequately financed and staffed, while motivation and staff development programmes need to enhancement in order toimprove the effectiveness of the delegation process. Key words: consult, delegating, leadership, responsibility, school principals.
