Target of all IRO attempts is the international mission, for what the participants have to fulfil requirements of the UN, which are primarily for the creation of a so called Urban Search and Rescue Team (USAR-Team). Building up a USAR-Team has to be done accordingly to the INSARAG guidelines (International Search and Rescue Advisory Group).
In the year 2007 the INSARAG Steering Committee, under the umbrella of the UN-OCHA, established the Search Dog Working Group (SDWG) to develop minimum criteria for rescue dog teams in international missions. The gathered criteria of the SDWG for international mission have been completely taken over into the IRO - Mission Readiness Test, so that the IRO-MRT is equivalent to the INSARAG minimum criteria.
