Dear all, 

The European Junior Olympiad in Informatics 2025 (https://2025.ejoi.org/) will take place in Shumen, Bulgaria, between August 29 and September 4. This year, we invite all countries to participate, regardless of their geographical location.

Each team can contain up to two team leaders and four participants born after December 31, 2009.

The team leaders and participants will be provided with accommodation, meals, ground transportation, excursions, and other cultural and scientific events. The organizers of EJOI 2025 will not cover medical insurance or any other expenses participants incur. For those arriving at the following airports, there will be an organized transfer to Shumen: Bucharest (Romania), Burgas, and Varna (Bulgaria).

The participation fee is 500 EUR for the European countries and 6000 EUR for all other countries.

If your country wishes to participate or has questions, please email ejoi2025_at_ejoi.org. If you are considering participating in the following years, please notify us via the official email, and we will include you in future emails. Please inform us of your willingness to participate by June 30.

If you need help organizing the national structure for the EJOI, feel free to contact me directly.
