International large-scale assessments such as the Programme for International Student Assessment (PISA) or the Programme for the International Assessment of Adult Competencies (PIAAC) have shaped the political landscape of how educational systems are evaluated and have led to profound reforms of educational systems across the world. Besides the political impact, large and representative data sets previously unknown have become available to researchers to pursue research questions that allow for the extensive application of data science, learning analytics, and big data analytics. These data sets contain information on “core domain” skills such as mathematics and reading, a host of background data, but also data on “21^st century skills” such as digital learning, problem solving, and collaboration. In this presentation, I will provide an overview of the history of large-scale assessments and give an update of recent additions and innovations putting the spotlight on some of the most influential assessments and their policy and research impact. There will be a specific focus on the emerging role of 21^st century skills and data science both in the reporting and analyses of large-scale assessment.
