Does Teacher Quality Affect Student Performance? Evidence from an Italian University

In this paper, we analyse whether the characteristics of university teaching staff matter with regard to students’ performance and interest in the discipline. We use data on about 1000 students enrolled on the first-level degree course in business and economics at a mediumsized Italian university. Thanks to the random assignment of students to different teaching classes during their first year, we are able to analyse the effect that teachers with different characteristics, in terms of experience and research productivity, produce both on students’ performance, measured in terms of the grades obtained at subsequent examinations, and on courses chosen. Our results suggest that teacher quality has statistically significant effects on students’ grades in subsequent courses. These effects are also robust after controlling for unobserved individual characteristics. On the other hand, we find less clear evidence when relating teacher quality to student involvement with a subject. It emerges that research productivity does not produce a statistically significant effect on the probability of a student undertaking additional courses in a subject, while more experienced teachers have a negative impact. However, also this effect does not become statistically significant when we run separate regressions for different disciplines.
