  • Abstract

    This data file contains competency scores (plausible values) for each participant in the domains ̶ Literacy ̶ Numeracy ̶ Problem solving in technology-rich environments as well as their background information. It contains more detailed information about respondents in Germany than the German public use file for PIAAC available at the OECD homepage ( The background questionnaire is divided in the following sections: A: General Information, such as age and gender; B: Education, such as highest educational achievement, current education, participation in continuing education; C: Current status and work history, such as paid work and unpaid work for family business, information on job search; D: Current work, such as profession, self-employment, and income; E: Recent work, such as profession, self-employment, reason for quitting; F: Skills used at work, such as influence and physical skills; G: Skill use Literacy, Numeracy and ICT at work; H: Skill use Literacy, Numeracy and ICT in everyday life; I: About yourself, such as readiness to learn and volunteering; J: Background information, such as country of birth, citizenship, language, parents’ profession. Additionally, the data file contains further derived variables, information on competency assessment, information on sampling and weighting, limited regional information and time information of the interview.
