The widespread belief is that youth, "digital natives", who live their entire lives in media-rich digital environments and are ubiquitously connected through social networks, naturally develop digital competencies. This study investigated digital literacies among 280 junior-high-school students with the aim of comparing participants' perceived digital literacy competencies and their actual performance in relevant digital tasks. The findings showed that only a few of participants' perceived skills were related to their actual performance. Generally, participants displayed high confidence in their digital literacies and significantly over-estimated their actual competencies.
