Facts, Figures, Remarks and Conclusions...

The interest in the Bebras movement and the number of participants increases every year. Participants of this international contest have to solve Informatics re-lated tasks, requiring no specific education in that field. Each of the tasks covers one or more categories of Computational Thinking (CT) and can be assigned to special domains of Computer Science (CS). Although the practical definition of CT is still a moving target, this challenge can be seen as a measurement tool for CT competencies.

In this paper, we present an analysis of different aspects of the Austrian Bebras competition over the last three years. Accumulated statistical datasets are com-pared and analyzed as well as detailed task solutions. Moreover, the data provide information about CT skills and CS domains mastered by the pupils and, con-versely, about difficulties in certain task categories. Accordingly, the evaluated data provided by the automatic testing system can be used to draw conclusions about the development of tasks.
