  • Abstract

    The National Assessment Study in Mathematics and Science 2012 (IQB Ländervergleich Mathematik und Naturwissenschaften 2012) is a nationwide large-scale assessment commissioned by the Standing Conference of the Ministers of Education and Cultural Affairs of the Länder (KMK) in the Federal Republic of Germany. The study was designed to assess students’ achievement in mathematics, biology, chemistry and physics and to evaluate to which extent they meet educational standards in the German Länder. About 44,500 grade 9 students participated in the study. In mathematics, all general competencies and content areas were tested and averaged to obtain a global score of mathematics proficiency. In Science, in turn, only the two content areas “content knowledge” and “scientific inquiry” were assessed for biology, chemistry and physics (see also Educational standards by subject). In addition to achievement tests, the study used questionnaires for students, parents, teachers and principals to assess curricular and extracurricular learning opportunities and to investigate which structures can be used to optimize learning processes. Indicators of the students’ reading abilities and basic cognitive abilities were also assessed.
