  abstract  = {This paper reviews empirical evidence on the effect of the composition of a student body on academic achievement of students. After defining the term composition effect, methodological aspects regarding the study of composition effects are considered. International and national evidence for the composition of a student body with respect to students' abilities, social, and ethnic background is then presented. Whereas international studies find evidence for social, ethnic, and achievement composition variables, national studies reveal that mean achievement level of a school or class is the most important composition variable in Germany. However, this effect is confounded with school track and social composition, which itself exerts a small incremental effect. Ethnic composition, however, does not seem to play an important role. The paper closes with a presentation of the underlying processes of composition effects and a discussion on how the composition of a student body is considered in school governance practices.},

  abstract  = {Secondary education is characterised by a sequence of transitions that are linked to educational inequality. Regarding social background effects, inequalities relate to disparities in educational achievement (primary effects) and educational decisions (secondary effects). In the present study, both primary and secondary effects are analysed based on an entire student cohort in the Hamburg school system (KESS study) across the course of secondary education, i.e. from entering secondary school to aiming for higher education. The KHB method is applied in order to decompose the effects, including transitions to upper secondary education. In line with previous research, total social background effects decrease across educational trajectories. No clear pattern emerges concerning an assumed increase in the relative importance of secondary effects. Primary effects operationalised by school grades are slightly predominant in the transition to lower secondary education, and nearly the same ratio is found for the transition to upper secondary education. However, regarding the aim to enter higher education, the relative importance of secondary effects is more clearly discernible.},

  abstract  = {The study investigates the effects of classroom composition (average ability, achievement, and socio-economic background, proportion of immigrant students) on the development in mathematics achievement, and reading literacy from grade 5 to 6. The study draws on a sample of N=1892 students in vocational track schools (Hauptschule) and intermediate track schools (Realschule) in Baden-Wuerttemberg, Germany. After controlling for school type, and between-school differences in student intake characteristics, none of the compositional characteristics showed a statistically significant effect on achievement development. School track was associated with the development of reading literacy even after controlling for individual differences; however, this relationship lost its statistical significance after the composition of the student body was additionally taken into account.},
