Teacher Professional Development (PD) programmes in Ghana aim to enhance educators' skills and knowledge, thereby improving student learning outcomes. However, there is limited research on the effectiveness of these programmes. The study employed a qualitative approach to analyse existing data and literature on PD programmes in Ghana. It also involved interviews with educators and students to gather insights into programme effectiveness. Findings indicate that while some PD programmes have shown positive effects, there is variability across different regions and subject areas. For instance, mathematics teachers reported significant improvements in teaching methods following PD interventions. PD programmes can significantly impact student learning outcomes, but their success depends on tailored approaches to address regional disparities and specific educational needs. To maximise the benefits of PD programmes, policymakers should invest in targeted training for educators and ensure that resources are distributed equitably across schools.
