EUC 2025 Rules

The ICPC Europe Championship 

ICPC Europe is organized into four contest regions: CERC (Central Europe), NWERC (North Europe), SEERC (South-East Europe), and SWERC (South-West Europe). These regions cover more than 40 countries and are home to more than 1500 universities among which many of the best-ranking universities in the World. In the 2023-24 Europe regional contests over 450 teams participated in the qualifying regionals to gain a spot in the World Finals. Participation has increased in recent years and since only a limited number of teams can advance to the World Finals, the Europe Championship (EUC) is a way to enlarge the World Finals experience to more teams in this Continent.

The 2025 ICPC Europe Championship (2025 ICPC EUC) will be hosted by University of Porto, from the 28th February till the 2nd of March, 2025. It is the second championship of Europe’s super-region.

Advancing to the ICPC Europe Championship

Qualification for the 2025 ICPC EUC is based on performance at European regional contests. In total, between 44 and 52 teams will qualify based on the following advancing rules:

  • Each region is conceded 25% of the slots in the EUC.
  • The best-ranked teams in each European regional, one per university, advance to the EUC.
  • A second team from a university, not yet qualified for the World Finals, ranking in the top 10 at the regional, advances to EUC;
