In 2021, 2022, and 2023 as part of the ySKILLS project, we explored how the digital skills of young people from six European countries change over time. In three waves of research, the same group of teenagers answered questions about their use of digital media every year. This report briefly summarizes the results of the second wave of research, conducted in a sample of 1.340 Polish students aged 13-17 from 12 schools (primary and secondary) in the Wielkopolskie and Mazowieckie voivodships. In this report, we first contextualize the research by describing the children's background, focusing on their individual and social characteristics. We then provide data on children's daily internet access, such as time spent online and digital devices used. Below is a list of the most common and most minor everyday activities of children online data on the digital skills of Polish teenagers in four dimensions: technological and operational, information and navigation, communication and interaction, content creation and production. Finally, we present data on the main digital risks experienced by Polish children.
