FISEC organises an annual international multi-sport event known as the FISEC Games, often referred to as the World School Games. The federation's members consist of national sports and school sports organisations that promote FISEC activities within their respective countries and participate in the FISEC Games.
The primary objective of FISEC is the organisation of the FISEC Games each year. Participation in the Games is open to FISEC member organisations and potential members. The competition is conducted for the 15–17 years age group, for both boys and girls.
The final selection of sports is determined based on the preliminary entries received from participating countries.
The FISEC Games are hosted by one of the member organisations and are usually held in the second week of July. The Games are conducted over a period of five days and, in addition to the sports competitions, place strong emphasis on cultural exchange, education, and international friendship.
