The PIAAC LogDataAnalyzer

Log files for 18 countries that participated in the first round of the Survey of Adult Skills, a product of the Programme for the International Assessment of Adult Competencies (PIAAC) (hereafter referred to as “PIAAC”) in 2011/12 have recently been released and can be downloaded from the German Social Science Infrastructure Services (GESIS) Data Catalogue (OECD, 2017[1]). More information and documentation is available at www.oecd.org/skills/piaac/log-file/. The files have been fully anonymised to prevent identification of individual respondents. The records can nevertheless be matched with information already available in the PIAAC Public Use File, which contains the individual answers to the background questionnaire, as well as the performance of test-takers in the PIAAC assessment.
