Research considering the effects of leadership training and development is underresearched. However, leadership behaviour can generate greater levels of performance and satisfaction. In this study, the effect of a group reflective learning programme for school leaders is examined. The study questions whether leadership development, using a group reflective learning programme that focuses on coaching skills, can influence teacher perceptions of the organizational learning climate. Gaining a deeper insight in factors influencing organizational learning climate is important because organizational learning climate is associated with job motivation, job satisfaction, positive working conditions and the optimizing of training outcomes. Hence, a positive organizational learning climate can contribute to organizational performance, in the case of primary education delivering quality education to pupils. Based on a sample of 289 teachers, it turned out that school leaders’ participation in the group reflective learning programme resulted in a significant increase of teachers’ perceptions of the organizational learning climate. The results are inspiring for scholars, policy makers and practitioners.
