- Little evidence of a negative effect of ethnic composition. On the contrary, when control for academic composition of the schools, find small, but positive, effects of attending a school with many minority students.
- The positive affect of ethnic composition that we find among the majority and second generation minorities does not yield for first generation minorities.
- Students from schools with a high proportion of ethnic minorities do not have a lower educational achievement than other students. Although there is a high correlation between ethnic composition and academic composition, we do not find that the (non-significant) effect of ethnic composition diminish when we control for the academic composition of the schools, rather contrary, it increases and becomes positive.
- Students from schools with a high proportion of ethnic minorities do not seek higher education to a lower degree. The effect of ethnic composition does not change as expected when we control for academic composition, however, it becomes positive and significant.
- The effect of ethnic composition on students’ educational attainment does not differ for minority and majority students.
- When we control for academic composition we find small, but positive, effects of ethnic composition. This result comprises both majority students and second generation minority students. Among the first generation minorities we find a negative effect of ethnic composition on educational achievement, but no effect on educational attainment.
