Washington

We describe the extent and predictors of staffing challenges faced by school districts in Washington state throughout the 2021–22 school year using data collected from job posting websites for districts representing more than 98% of students in the state. These data suggest that school districts in the state faced considerable challenges filling paraeducator and, to a lesser extent, teaching positions at the beginning of the school year.

Taking advanced courses in high school predicts a broad array of positive postsecondary and labor market outcomes. Yet students from historically disadvantaged groups and low-income backgrounds have long been underrepresented in these courses. To address this problem, more than 60 districts in Washington state implemented a policy that automatically enrolled all qualified high school students in advanced coursework. The policy relied on a simple behavioral nudge: It made advanced courses “opt out” rather than “opt in” for all qualified students.

In many school districts the policies that regulate personnel are governed by collective bargaining agreements (CBAs) negotiated between teachers’ unions and school boards. While there is significant policy attention and, in some cases, legislative action that has affected the scope of these agreements, there is relatively little research that assesses how CBAs vary over time, or whether they change in response to states’ legislative reforms.

We use longitudinal data from North Carolina and Washington to study the extent to which four processes—teacher attrition from each state workforce, teacher mobility within districts, teacher mobility across districts, and teacher hiring—contribute to “teacher quality gaps” (TQGs) between advantaged and disadvantaged schools.

We use a novel database of the preservice apprenticeships (“student teaching placements”) of teachers in Washington State to investigate the relationship between mentor effectiveness (as measured by value added) and the future effectiveness of their mentees. We find a strong, positive relationship between the effectiveness of a teacher’s mentor and their own effectiveness in math and a more modest relationship in English Language Arts.

We exploit within-teacher variation in the years that teachers 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. The average causal effect of hosting a student teacher on student performance in the year of the apprenticeship is precisely estimated and indistinguishable from zero in both math and reading, though effects are large and negative in math when ineffective teachers host an apprentice.
