Secondary schools incorporate strategic planning practices in their management processes but their effect on performance had not been subject to widespread assessment through empirical research. Strategic planning practices are key to improvement of the schools performance. Schools' management team should be trained on strategic management skills to effectively employ strategic planning practices to enhance the schools' performance. This is due to the increasing pressure from the various stakeholders to have schools compete effectively and deliver in the pursuit of knowledge. As a starting point every school should have a strategic plan in place, followed by effective implementation, and monitoring and evaluation.
