With teacher quality repeatedly cited as the most important "schooling" factor influencing student achievement, there has been increased interest in examining the efficacy of teacher training programs. This paper presents the results of research investigating the relationship between teachers who graduate from different training programs and…

In a provocative and influential paper, Jesse Rothstein (2010) finds that standard value added models (VAMs) suggest implausible future teacher effects on past student achievement, a finding that obviously cannot be viewed as causal. This is the basis of a falsification test (the Rothstein falsification test) that appears to indicate bias in VAM…

With teacher quality repeatedly cited as the most important "schooling" factor influencing student achievement, there has been increased interest in examining the efficacy of teacher training programs. This paper presents research examining the variation between and impact that individual teacher training institutions in Washington State have on…

There is significant and growing interest in teacher pay reform as a number of states and localities have begun experimenting with departures from the single salary schedule--a pay system employed in most school districts, which links teacher pay solely to degree and experience level (Chait, 2007; Goldhaber, 2009; Podgursky and Springer, 2007).…

Over 2,000 teachers in the state of Washington received reduction-in-force (RIF) notices across the 2008-09 and 2009-10 school years. We link data on these RIF notices to an administrative dataset that includes student, teacher, school, and district variables to determine the factors that predict the likelihood of a teacher receiving a RIF notice.…

This paper reports on findings based on analyses of a unique dataset collected by ACT that includes information on student achievement in a variety of subjects at the high school level, which allow us to examine the relationship between teacher effect estimates derived from VAM specifications employing different student learning assumptions.…

In this paper we examine the mobility of early-career teachers of varying quality, measured using value-added estimates of teacher performance. Unlike previous studies that have examined these issues, we focus on the variation in these effects across the effectiveness distribution. We find that, on average, more effective teachers tend to stay in…

Stories about the importance of teacher effectiveness for student achievement are currently ubiquitous in the media (Gladwell 2008; Kristoff 2009; Felch et al 2010). Teacher quality is also the focus of significant national efforts and investments. A growing body of quantitative research supports the focus on teacher and teacher effectiveness.…

Education research convincingly shows that teacher quality is the most important "schooling" factor influencing student achievement. A very good teacher as opposed to a very bad one can make as much as a "full year's" difference in learning growth for students. Indeed, the effect of increases in teacher quality swamps the impact of any other…

Economic theory commonly models unobserved worker quality as a given parameter that is fixed over time, but empirical evidence supporting this assumption is sparse. In this paper we report on work estimating the stability of value-added estimates of teacher effects, an important area of investigation given that new workforce policies implicitly…

In this paper, the author discusses the role of methodology in assessing the effects of teacher qualifications on teacher effectiveness (also commonly referred to as the "quality of teaching"). The author focuses on some of the statistical problems that can arise in a non-experimental setting and the ways in which statisticians attempt to deal…
