Tasks are very important both for competitors (students) and task developers (teachers):
Students are being “pushed” to think on informatics, whereas educators should think about harmonization of syllabus of computer science. Creative, interesting tasks are the main drive for the Bebras contests.
The Bebras tasks’ developers seek to choose interesting tasks in order to motivate students to deal with informatics and to think deeper about technology. Also, they would like to cover as many as possible topics on informatics and computer literacy. In informatics, there is also the problem of syllabus. Even if there is an education standard for informatics at school in some countries, till now there is no common agreement what should be included in an integrated syllabus using information technologies.
A good Bebras task should be
