This paper investigates how the precision and stability of a teacher's value-added estimate relates to the characteristics of the teacher's students. Using a large administrative data set and a variety of teacher value-added estimators, it finds that the stability over time of teacher...

A growing literature establishes that good teachers are essential for high quality educational systems. However, little is known about teachers' skills formation during their college years. In this paper we use a novel panel data set combining two standardized tests for Colombian students: one...

In a previous paper, we have shown that academic rank is largely unrelated to tutorial teaching effectiveness. In this paper, we further explore the effectiveness of the lowest-ranked instructors: students. We confirm that students are almost as effective as senior instructors, and we produce...

The influx of immigrants has shifted the ethnic composition of public schools in many states including North Carolina. Recent evidence from North Carolina suggests that increases in Limited English students' concentration have led to a slight decline in performance solely for students at the top...

There is a perception among native born parents in the U.S. that the increasing number of immigrant students in schools creates negative peer effects on their children. In North Carolina there has been a significant increase in immigrants especially those with limited English language skills and...

We examine the role of education in fostering the economic integration of immigrants. Although immigrants in Europe are – on average – slightly less educated than native individuals, there is a large heterogeneity across countries. We discuss evidence on student performance in international...

Students are admitted into higher education based on their past performance. This paper compares two measures of past cognitive skills: teacher and national exam scores. By using a nationwide dataset, we look at how the predictive power of teacher assessment and exam scores for selecting...

We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...
