To maintain this capacity and preparedness, UNHCR has developed training programmes that are held at regular intervals. They include the Workshop on Emergency Management, or WEM, which prepares all volunteers on UNHCR's ERT rosters. This weeklong exercise is held four times a year for up to 40 people and every effort is made to create the atmosphere of an actual emergency deployment. The main subjects include team-building, operations planning, financial and administrative systems, operational partnerships, communication and negotiation skills, security, coordination and information-sharing, telecommunications, and humanitarian protection.
