This article researches whether approaches to moral education aim to influence the development of the personal worldview of students. An example of a Dutch moral education programme is presented and the findings are used to analyse various approaches to moral education. Our analysis demonstrates that every approach aims to influence the personal worldview of students because of underlying ontological beliefs. This is the inevitable and minimal influence a moral education approach has on personal worldview. Our analysis also demonstrates that two approaches go further: Aristotle's virtue ethics and Kantian deontological ethics. Both aim to contribute to the personal worldview development because they aim to influence the broad moral views (ethical and teleological matters) students have.
