Ans: The Ministry that sends the students to the competition covers the costs of their participation in the IOAA. They pay for the round-trip fare. The Education Ministry, which sends the students, also covers the costs of the accompanying individual. The organising country's ministry is responsible for all costs associated with the gathering, including lodging, excursions, awards, and other expenses. Since this is an educational event, the host country makes all of the necessary arrangements for all of the participating countries' teams. The costs are covered by the host country from the moment the teams arrive in the country.
