Soziale Ungleichheiten in der Kompetenzentwicklung in der Grundschule und der Sekundarstufe I

The article focuses on the question how competencies of students with different social backgrounds develop during elementary and secondary school. In particular, it addresses if achievement disparities which exist before school entrance increase, remain stable, or even diminish during schooling. The article draws on both national and international studies with longitudinal designs examining the achievement development of students of different social backgrounds during primary or secondary school. Although the results are mixed to some extent, a large part indicates that differences in achievement increase during the time of schooling. The evidence seems more consistent for achievement development during elementary school. Additionally, there is some indication that schools and features of the educational system contribute to increasing achievement disparities between students of different social backgrounds.
