Ability Grouping And Academic Inequality: Evidence From Trinidad And Tobago, Clement (Kirabo) Jackson Dec 2007

Ability Grouping And Academic Inequality: Evidence From Trinidad And Tobago, Clement (Kirabo) Jackson

C. Kirabo Jackson

In Trinidad and Tobago students are assigned to secondary schools after fifth grade based on achievement tests, generating large differences in school and peer quality. Using instrumental variables to address self-selection bias, I find that being assigned to a school with high-achieving peers has large positive effects on examination performance, particularly for girls. This suggests that ability grouping (or school tracking) reinforces achievement differences by assigning the weakest students to schools that provide the least value-added. While students benefit from attending schools with brighter peers on average, the marginal effect is non-linear such that there are small benefits to attending …

Teaching Students And Teaching Each Other: The Importance Of Peer Learning For Teachers (With Elias Bruegmann), Clement (Kirabo) Jackson

C. Kirabo Jackson

Using student examination data linked to longitudinal teacher personnel data we document that a teacher’s students have larger test score gains when she experiences an improvement in the observable characteristics of her colleagues. Using within-school and within-teacher variation, we further show that a teacher’s students have larger test score gains when she has more effective colleagues (based on their own students’ achievement gains from an out-of-sample pre-period). A one standard deviation increase in average teacher peer quality is associated with an increase of 0.02 and 0.04 standard deviations in student test scores in reading and math respectively (about one third …


Student Demographics, Teacher Sorting And Teacher Quality: Evidence From The End Of School Desegregation, Clement (Kirabo) Jackson Dec 2007

Student Demographics, Teacher Sorting And Teacher Quality: Evidence From The End Of School Desegregation, Clement (Kirabo) Jackson

The reshuffling of students due to the end of student busing in Charlotte-Mecklenburg provides a unique opportunity to investigate the relationship between changes in student attributes and changes in teacher quality that is not confounded with changes in school or neighborhood characteristics. Comparisons of OLS and IV results suggest that the spatial correlation between teachers’ residences, students’ residences and schools could lead to spurious correlation between student attributes and teacher characteristics. The reshuffling of students led to teacher re-sorting so that schools that experienced a repatriation of black students experienced a decrease in various measures of teacher quality (including estimated …
