The diagram below is a summary of a Theory of Change for interventions in the education sector in Country X. It did not stand on its own, it was supplemented by an extensive text description.
Its complex in the sense that there are many different parts to it and many interconnections between them, including some feedback loops. It seems realistic in the sense of capturing some of the complexity of social change. But it may be unrealistic if it is a prescription for achieving change. Whether it is the later depends on how we interpret the diagram, which I discuss below.
