Welcome to the Czech website of the contest "Bobřík informatiky".

The Beaver of Informatics is a contest organized for primary, secondary and high school students. The contest offers the possibility to compete and to popularise informatics at school and also among students – fans of computing. The main goal of the contest is to show students and their teachers the whole rank of informatics which teaching is often reduced to digital literacy training. Another aim is to show them which knowledge and skills are required from IT specialists and also turn attention to the grounfs and principles of informatics as a science so that schools would be able to form students prepared to IT university studies having an undistorted idea of „computer science studies“.

The contest is a member of a cluster of national contests BEBRAS of the same aim and similar organization. More than 40 countries organized the contest last year. The international web for the whole cluster is www.bebras.org. All these countries use common methodological centre that set up some non-committal rules and recommend a set of problems. Contest tasks were taken partly from international database and partly from own resources. We prepare about 80 new tasks every year.

In the Czech contest, students fill in an online test on a web browser. Test duration is 40 minutes, the test contains 15 tasks with 4 answers to be selected. Several tasks are interactive and can be solved by manipulation with object by mouse. Participants are split into age categories (or school grade categories): Mini (about 10 - 11 years old pupils), Benjamin (about 12 – 13 years old), Kadet (14 – 15 years old), Junior (16-17 years old) and Senior (18-19 years old). We organize second round of the contest for best contestants in category Senior.

The national contest is held every November, each category an extra day. In 2014, the 7-th national contest was held. Number of participants increases during last years: 2008: 4048, 2009: 10351, 2010: 14867, 2011: 19280, 2012: 27550, 2013: 34454, 2014: 44083, 2015: 52597, 2016:71792.

From 2015, we organize 14 regional rounds in category Senior (upper high school). 30 best participants from national round in every region can advance to the regional round.  


Ratio of girl participants is more than 40 % altogether and about 49 % at elementary schools.

The tasks come from 4 areas: algorithmization (including programming), information representation (including coding, encrypting and structures), digital literacy (including social tasks) and problem solving (including strategies, logical and mathematical background of informatics). The archive of tasks and tests is accessible under the link Archiv (tasks are only in Czech).

The guarantee of the national contest is the Department of Informatics at the Faculty of Education, University of South Bohemia in České Budějovice (www.pf.jcu.cz) and runs the contest with collaboration of Technical University Liberec. The patron of the contest is The Unit of School Informaticians, the Czech professional corporation of ICT teachers (www.jsi.cz). The contest is supported by Ministry of Education of the Czech Republic. Main supposers are RSJ Foundation and Web4U.
