We examine whether and how teachers' major fields of study affect students' achievement, exploiting within-student variation across subfields in natural science (i.e., physics, chemistry, biology, and Earth science). Using middle-school students' data from the Trends in International Mathematics...

Italy's secondary school system has faced funding constraints for many years which limits availability of new permanent job slots for teachers. When permanent posts do arise they are allocated mostly on seniority while merit only plays a small role. Thus, the age distribution of teachers in...

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...

The federal government's Race to the Top competition has promoted the adoption of test-based performance measures as a component of teacher evaluations throughout many states, but the validity of these measures has been controversial among researchers and widely contested by teachers' unions. A...

We study whether reallocating existing teachers across schools within a district can increase student achievement, and what policies would help achieve these gains. Using a model of multi-dimensional value-added, we find meaningful achievement gains from reallocating teachers within a district....

Teachers differ greatly in how much they teach their students, but little is known about which teacher attributes account for this. We estimate the causal effect of teacher subject knowledge on student achievement using within-teacher within-student variation, exploiting a unique Peruvian...

This paper examines the widespread perception in India that the country has an acute teacher shortage of about one million teachers in public elementary schools, a view repeated in India's National Education Policy 2020. Using official DISE data, we show that there is hardly any net teacher...

We examine the role of teachers and students in the formation of test scores at the higher secondary level (grade 12) in public schools in Delhi, India. Using the value added approach, we find substantial variation in teacher and student quality within schools: over the period spanning grades 11...

While in-service teacher training programs are designed to enhance the performance of several cohorts of students, there is little evidence on the persistence of their effects. We present the two-year results of a large-scale, randomized study of an intensive in-service teacher training program...

This paper distills and extends recent research on the economics of human development and social mobility. It summarizes the evidence from diverse literatures on the importance of early life conditions in shaping multiple life skills and the evidence on critical and sensitive investment periods...
