Research on teacher churn has produced conflicting conclusions as to its impact on students and teachers. We bring clarity to this work by combining and expanding on analytical approaches used in earlier research to determine how and when different types of churn (i.e., grade, school) impact teacher effectiveness and attendance. Using data from…

We use a novel database of student teaching placements in Washington State to investigate teachers' transitions from student teaching classrooms to first job classrooms and the implications for student achievement. We find first-year teachers are more effective when they teach in the same or an adjacent grade, in the same school type, or in a…

Educators raise concerns about what happens to students when they are exposed to new or new-to-school teachers. However, even when teachers remain in the same school they can switch roles by moving grades and/or subjects. We use panel data from New York City to compare four ways in which teachers are new to assignment: new to teaching, new to…

Retaining effective teachers is a key policy priority nationwide, particularly in districts that serve large numbers of disadvantaged students. We investigate whether a change in the Miami region's Teach for America (TFA) placement strategy was accompanied by changes in teacher attrition and mobility decisions. Our results suggest that the…

Using student survey data from six U.S. school districts, we estimate how assignment to a demographically similar teacher affects student reports of personal effort, happiness in class, feeling cared for and motivated by their teacher, the quality of student-teacher communication, and college aspirations. Relying on a classroom fixed-effects…

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…

Collective bargaining is common in American public education, but its consequences are poorly understood. We focus here on key contractual provisions--seniority-based transfer rights--that affect teacher assignments, and we show that these transfer rights operate to burden disadvantaged schools with higher percentages of inexperienced teachers. We…

Despite policy efforts to encourage multiple measures of performance in newly developing teacher evaluation systems, practical constraints often result in evaluations based predominantly on formal classroom observations. Yet there is limited knowledge of how these observational measures relate to student achievement. This article leverages the…

Faced with mounting policy pressures from federal and state accountability programs, school leaders are reallocating curricula, time, even diet in an attempt to boost student achievement. To explore whether they are using test score data to reallocate their teacher resources as well, I designed a cross-case, cross-sectional study and explored…

Teach For America (TFA) recruits high-achieving college graduates to teach for 2 years in the nation's low-income schools. This study is the first to examine these teachers' retention nationwide, asking whether, when, and why they voluntarily transfer from their low-income placement schools or leave teaching altogether. Based on a survey of three…

This article investigates the key determinants of entry into the teaching profession and the subsequent sorting of new teachers across urban, suburban, and rural schools. Of particular interest is the relative importance of teacher salaries, alternative labor market opportunities, and nonpecuniary job attributes or working conditions to this…

A case study of Boston (Massachusetts) public schools shows how specialization and fragmentation of teaching resources reduced the individual attention most students received and limited a school's flexibility to respond to student needs. The analysis develops three measures as possible indicators of the opportunity for freeing teacher resources.…

Demographic changes in college graduates who received teaching certificates between 1975 and 1985 are assessed. The effects of demographic characteristics, subject specialties, and scores on National Teacher Examinations on certificants becoming teachers in North Carolina are examined. Results highlight the need for more Black college students to…
