The clinical teaching experience is one of the most important components of teacher preparation. Prior observational research has found that more effective mentors and schools with better professional climates are associated with better preparation for teacher candidates. We test these findings using an experimental assignment of teacher…

We use a unique dataset of student teaching placements in the State of Washington and a proxy for teacher shortages, the proportion of new teacher hires in a school or district with emergency teaching credentials, to provide the first empirical evidence of a relationship between student teaching placements and teacher shortages. We find that…

We use a database of over 15,000 teacher candidates from 15 teacher education programs in Washington state to investigate the connections between specific teacher preparation experiences and the likelihood that these candidates enter and stay in the state's public teaching workforce. As has been found in prior research, candidates with…

We test these findings using an experimental assignment of teacher…

Prior research has connected characteristics of cooperating teachers who supervise student teaching to performance measures of the teacher candidates they host, suggesting more effective teachers may also be better mentors. The specific measures of cooperating teacher effectiveness considered in this prior literature (value added and performance…

A growing literature documents the importance of student teaching placements for teacher development. Emerging evidence from this literature highlights the importance of the mentor teacher who supervises this placement, as teachers tend to be more effective when they student teach with a mentor who is a more effective teacher. But the efficacy of…

The overwhelming majority of public school teachers enter the teaching profession only after completing an apprenticeship as a student teacher. A growing body of research demonstrates how important the student teaching experience, also known as clinical practice, is for developing teaching capacities and shaping teacher career paths. But recent…

Prior research has shown that about 15% of teachers are hired into the same school in which they student taught, about 40% are hired into their student teaching district, and the location of teachers' student teaching placements is more predictive of where they are hired than where they went to high school or college. While this suggests that…

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…

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 that first-year teachers are more effective when they are teaching in the same grade, in the same school level, or in a…

COVID-19 profoundly affected teacher preparation during the 2019-20 school year. Based on survey responses from nearly all Washington state teacher education programs (TEPs), Kathryn Choate, Dan Goldhaber, and Roddy Theobald find that the pandemic had predictable but concerning effects on teacher preparation. Most notably, student-teaching…

We use comprehensive data on student teaching placements from 14 teacher education programs (TEPs) in Washington State to explore the sorting of teacher candidates to the teachers who supervise their student teaching ("cooperating teachers") and the schools in which student teaching occurs. We find that, all else equal, teachers with…

A growing quantitative literature finds evidence that student teaching placements predict later outcomes of teacher candidates and their students, but there is little large-scale quantitative evidence about the mechanisms for these estimated relationships. We use data from a survey of STEM teachers in Washington State to better understand how…

We exploit within-teacher variation in the years that math and reading teachers in grades 4-8 host an apprentice ("student teacher") in Washington State to estimate the causal effect of these apprenticeships on student achievement, both during the apprenticeship and afterwards. While the average causal effect of hosting a student teacher…
