The following article aims to conceptualise dialogue as a teachable strategy that allows to generate active processes of listening, problem-solving tasks, ethical formation, and acceptance of the other within the context of pluralist schools. Dialogue is identified as a key space for reflection and communication, comprehending that this entails particularities such as resistance and asymmetry in terms of power. On the other hand, pluralist schools base their structure on the coexistence of diverse cultures which are mutually benefited through dialogue. Nevertheless, it is necessary to understand that the others' culture's validation and acceptance move through the ethical perspective from which the communication between the actors occur. All in all, dialogue constitutes a crucial strategy for diversity and coexistence in the pluralist and democratic schools.
