European School Sport Federation (ESSF) was founded in March 2020 with the aim of providing primary school students with the opportunity to compete at the international level. As a young organization, it is based on all the values of International School Sport Federation (ISF).

The Federation primary activity is sports competitions, but also deals with other special projects with a goal of popularization of school sports among European youth.

The president of ESSF is Zeljko Tanaskovic, who is a former Serbian volleyball player, winner of numerous medals at World, European and Olympic games. Today, he is a prominent sports worker who has practically dedicated his life to the development of school sport.
