I'll tell you about a competition among Czech journalists, and also about an interesting thing specifically for students - Google award for young talents in data journalism.
You can read about the award here (caution, Czech language).
In the picture you can see what exactly this competition is. For those who don't understand Czech, I'll tell very briefly. Students (and in general everyone) under 30 years old can send their interesting idea to the competition. The idea should concern data journalism. This needs to be done before the end of January. You can even send an unfinished idea, having a ready project on hand is not mandatory. Winners will receive 10,000 crowns each, as well as help from ihned.cz editors.
I myself will try to send something in the near future, fortunately, there's a little interest. In any case, the event takes place every year, so you can try next year too.
