Teacher-student assortative matching and student achievement

Teacher-student assortative matching and student achievement
What does the research say?

In this study, we investigate the extent of positive assortative matching between teacher and student characteristics and its relation to student achievement. Using administrative data on all Dutch primary school teachers between 2008 and 2016, we find that there is strong positive assortative matching on education levels and migrant background, particularly in urbanized areas. Sorting of early career teachers exacerbates the differences in average teacher characteristics between schools. The school share of non-western migrant teachers relates positively to test scores of migrant students, with no negative effect found for natives. In contrast, a higher share of teachers holding a master’s degree is unrelated to test scores of students with university-educated parents. The results suggest no negative consequences of teacher sorting on students’ parental educational background in terms of test scores, while positive assortative matching along migration background could increase educational effectiveness.

What are the main conclusions?
  1. Strong sorting of teacher and student characteristics along educational lines and migration background, particularly in highly urbanized areas
  2. Sorting patterns of young teachers exacerbate the patterns found on average
  3. No relationship between the share of teachers holding a master’s degree and student achievement
  4. Positive interaction between the share of teachers from a non-western migration background and achievement of students with a migration background
