 The conference is generally held in March.WorldMUN uses the American style of Model United Nations, with almost all delegates paired with another from their delegation (in dual delegations), with discussions occurring both inside and outside the rooms simultaneously.Committees have in the past included committees of the United Nations General Assembly, the Security Council, the subcommittees of ECOSOC, regional bodies (such as the African Union or European Union), specialized agencies of the United Nations, crisis simulation committees and uniquely, simulations of the entire general assembly.
