This study profile presents the Russian panel study Trajectories in Education and Careers (TrEC). This longitudinal project has been conducted in Russia since 2009 and comprises one national panel and several regional panels of school and university students. The national panel is a longitudinal follow-up with the participants of the Trends in International Mathematics and Science Study (TIMSS) in Russia, who were eighth-grade students in 2011 (aged 13–14) and have been interviewed yearly since then. The unique feature of the national panel is that its respondents also took the tests in the Programme for International Student Assessment (PISA) in 2012, as an additional sample of that study in Russia. The paper gives an outline of TrEC’s progress to date, focusing on its design, data collection and data description. Researchers from all over the world are invited to submit research proposals and analyse TrEC data.
