High rates of teacher turnover in child care settings have negative implications for young children’s learning experiences and for efforts to improve child care quality. Prior research has explored the prevalence and predictors of turnover at the individual teacher level, but less is known about turnover at the center level – specifically, how turnover varies across child care centers or whether staffing challenges persist year after year for some centers. This study tracks annual turnover rates for all publicly funded child care centers that were continuously operating in Louisiana from the 2015-16 to 2018-19 school years (n=575 centers). We document high and variable turnover rates across centers throughout the state: The annual mean turnover rate was 40%, and each year nearly one-third of centers experienced high turnover, that is, lost more than half of their teachers. About 27% of centers experienced high turnover for multiple years in our panel, while 44% of centers did not experience high turnover in any year. Our findings underscore concerns that sustained staffing challenges may hinder efforts to provide high-quality child care.

This study assesses the effects of two text messaging programs for parents that aim to support the development of math skills in prekindergarten students. One program focuses purely on math, while the other takes an identical approach but focuses on a combination of math, literacy, and social-emotional skills. We find no evidence that the math-only program benefits children’s math development. However, the combination program shows greater promise, particularly for girls. Quantile regressions indicate that the effects are concentrated in the lower half of the outcome distribution. We discuss and provide evidence for various hypotheses that could explain these differences.


  • We test the effects of two text messaging curricula that leverage behavioral economics principles to help parents support the math development of prekindergarteners in the home.
  • We find that a program that cycles through literacy, mathematics, and social-emotional skills increases math achievement for girls, while a program focusing solely on mathematics has no effects.
  • Benefits for girls are concentrated on those with weaker performance on mathematics assessments.
  • We posit potential mechanisms based on the literature.

The early childhood enrollment process involves searching for programs, applying, verifying eligibility(for publicly funded seats), and enrolling. Many families do not complete the process. We conducted a randomized controlled trial to assess strategies for communicating with families as they verify eligibility. Working with administrators in New Orleans, we randomly assigned families to receive either: (1) the district’s usual, modest communications, (2) the usual communications plus weekly text-message reminders formal in tone, or (3) the usual communications plus weekly text-messages reminders friendly and personal in tone. Text-message reminders increased verification rates by seven percentage points (regardless of tone), and personalized messages increased enrollment rates for some groups. The exchanges between parents and administrators reveal the key obstacles that parents confronted.
