This paper provides a longitudinal examination of teacher turnover across all publicly-funded, center-based early childhood sites in Louisiana. We follow 4,465 early educators teaching in fall 2016 up to seven times through the fall of 2019. We provide the first statewide estimates of within-year turnover in ECE, as well as the first statewide study tracking turnover rates in ECE over multiple years. We find high within-year turnover: about 10% of teachers observed in the fall are not teaching the following spring. We also show that over 60% of fall 2016 teachers are no longer teaching at the same site in fall 2019. Turnover is particularly high among child care teachers, teachers of toddlers, and new teachers.

During the past fifteen years, immigration enforcement increased dramatically in the U.S. interior. There is a growing recognition that immigration enforcement in the U.S. interior has spillover effects onto U.S. citizens. I examine the impacts of a type of partnership between Immigration and Customs Enforcement (ICE) and local law enforcement, 287(g) programs, on school engagement within North Carolina. In North Carolina, nine counties were approved to establish 287(g) programs, and another fifteen applied but were not approved to participate. I use a triple difference strategy in which I compare educational outcomes for different groups of students in these two sets of counties before and after activation of 287(g) programs. I find that 287(g) programs decrease school engagement by decreasing attendance. This effect appears to be driven by increases in chronic absenteeism (missing 15 or more days per year). In contrast, I observe no effect of 287(g) programs on achievement.

At least sixteen US states have taken steps toward holding teacher preparation programs (TPPs) accountable for teacher value-added to student test scores. Yet it is unclear whether teacher quality differences between TPPs are large enough to make an accountability system worthwhile. Several statistical practices can make differences between TPPs appear larger and more significant than they are. We reanalyze TPP evaluations from 6 states—New York, Louisiana, Missouri, Washington, Texas, and Florida—using appropriate methods implemented by our new caterpillar command for Stata. Our results show that teacher quality differences between most TPPs are negligible—.01-.03 standard deviations in student test scores—even in states where larger differences were reported previously. While ranking all a state’s TPPs may not be possible or desirable, in some states and subjects we can find a single TPP whose teachers stand out as significantly above or below average. Such exceptional TPPs may reward further study.
