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 policies that aim to have effective teachers serve as mentors depends a great deal on the availability of effective teachers to serve in this role. We therefore use data from Washington State to illustrate that there is ample scope for change in student teacher placements; in other words, there are far more effective teachers within fifty miles of a teacher education program (TEP) who could host a student teacher in each year than the number of teachers who serve in this role. We also discuss the considerable challenges to improvement efforts related to the need for better coordination between TEPs, K–12 school systems, and states. Finally, we argue that, if policy makers value teacher candidate development equivalently to teacher in-service development, they should be willing to pay substantially more than the current average compensation for mentor teachers to recruit effective teachers to serve in this role.

We used data on the student teaching placements, degrees, teaching credentials, and workforce outcomes of more than 1,300 graduates of special education teacher education programs in Washington to provide a descriptive portrait of specific measures of special education teacher preparation and their relationships with workforce entry and early-career retention. Although rates of workforce entry and retention for these special education candidates were high, we documented considerably lower rates of entry into and retention in special education teaching positions for candidates who hold a dual endorsement in special education and another subject. These patterns have potential implications for the state’s new dual-endorsement requirement and for dual-licensure programs more broadly. Student teaching with a cooperating teacher who is endorsed in special education was also associated with a higher likelihood of becoming a special education teacher, even when controlling for whether the placement was in a special or general education setting.

Using unique data from California on teacher job vacancies, we investigate staffing challenges across the urbanicity spectrum, focusing on the extent to which the characteristics of rural school systems explain the differences in staffing challenges as measured by vacancy rates and emergency credentialed teachers, relative to other urbanicities. We find that rural districts have significantly and substantially higher staffing challenges than districts from different urbanicity classifications (urban, suburban, and towns). Some of these differences are explained by district-level attributes, such as the proportion of students in poverty in the district. The geography of rural districts itself also explains the high levels of staffing challenge as rural districts are more likely to be located on a state border and far from teacher education programs, both of which are strongly associated with staffing challenge measures. Even after controlling for a rich set of observable covariates, there is evidence that rural districts are still somewhat more likely to face staffing challenges, suggesting that there are unobserved aspects of being rural associated with the desirability of employment that are not readily captured by quantitative data.

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 schools and districts that host fewer student teachers or are nearby to districts that host fewer student teachers tend to hire significantly more new teachers with emergency credentials the following year. These relationships are robust to district fixed-effects specifications that make comparisons across schools within the same district. This descriptive evidence suggests exploring efforts to place student teachers in schools and districts that struggle to staff their classrooms.
