Model United Nations, also known as Model UN or MUN, is an educational simulation and academic activity. Simulation of the UN world over has become nurturing grounds for future world leaders. From researching and deliberating, to negotiating and resolving, young MUNers engage in the world of political, economic, social and security issues to make the world a better place to live in.

MUN provides a platform to the participants where they not just role play the solutions put forward in the real UN conferences but also challenge and sharpen their own intellect and critical/ analytical thinking skills and take their thoughts to a whole new level of distinction.MUN teaches the delegates researching, public speaking, debating,writing skills, teamwork, and leadership abilities.

At DPSSL the MUN is a passion. The process of grooming the interested students begins from class VIII onwards. The orientation by the senior members of MUN team marks the first step. In this activity,the new joinees are introduced to the technicalities through PPT presentations and demos. This is followed by the Intra MUN, where the participants practice what they have learnt in the orientation sessions. Also there are seniors to help them in honing their skills. A data base is created of the potential MUNers and they then represent the school in various inter school MUN conferences.
