This article draws from a study that explored how Ugandan secondary school teachers' competences are continuously developed to cope with the ever changing trends in Science and Mathematics teaching. The study was premised on a framework of professional development that views teacher education as a continuum that includes training, recruiting, retaining, and retraining. The article argues that in Uganda more research has been focused on the first two levels of the continuum, with evidence on the last one remaining less documented. Data was largely collected from qualitative semi-structured interviews with selected policy makers, school administrators, and teachers. The interviews were complemented with an analysis of relevant documents and a workshop with the participating teachers. A thematic analysis of the data revealed three categories of existing Continuing Professional Development programmes in Uganda including those initiated by government agencies and donors; those initiated by schools; and those initiated by individual teachers. The article highlights the need for a critical examination of these existing programmes with a view to ensuring that they reinforce each other.
