We rely on natural experiments in North Carolina and Washington State, which previously extended time to tenure by one year, to estimate models that assess the relationship between the extended probationary period and absence and attrition outcomes for teachers affected by the new tenure laws. Across both states we find evidence of decreases in…

We use data from six Washington State teacher education programs to investigate the relationship between teacher candidates' student teaching experiences and their later teaching effectiveness. Our primary finding is that teachers are more effective when the student demographics of their current school are similar to the student demographics of…

We use data from Washington State to examine two stages of the teacher pipeline: the placement of prospective teachers into student teaching assignments and the hiring of prospective teachers into their first teaching positions. We find that prospective teachers are likely to complete their student teaching near their college and hometowns but…

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations--middle school math, ninth-grade algebra and geometry, and ninth-grade biology--and find evidence that a teacher's basic skills test scores are modestly predictive of student…

We use data from Washington State to examine two stages of the teacher pipeline: the placement of prospective teachers in student teaching assignments; and the hiring of prospective teachers into their first teaching positions. We find that prospective teachers are likely to complete their student teaching near their college and hometowns, but…

We use data from Washington State to examine two distinct stages of the teacher pipeline: the placement of prospective teachers in student teaching assignments; and the hiring of prospective teachers into their first teaching positions. We find that prospective teachers are likely to complete their student teaching near their college and…

Barriers to the cross-state mobility of the teacher workforce can have undesirable effects on the teacher workforce and student outcomes. While a large literature addresses issues related to within-state mobility, very little is known about patterns of cross-state mobility. This paper addresses that research gap. We describe features of Oregon's…

There is mounting evidence of substantial "teacher quality gaps" (TQGs) between advantaged and disadvantaged students, but practically no empirical evidence about their history. We use longitudinal data on public school students, teachers, and schools from two states--North Carolina and Washington--to provide a descriptive history of the…

We study the effectiveness of teachers certified by the National Board for Professional Teaching Standards (NBPTS) in Washington State, which has one of the largest populations of National Board Certified Teachers (NBCTs) in the nation. Based on value-added models in math and reading, we find that NBPTS certified teachers are about 0.01-0.05…
