Research Findings: The Classroom Assessment Scoring System Toddler (CLASS-T) is one of the most commonly used measures to assess the quality of teacher-child interactions in toddler classrooms. Despite widespread use of the CLASS-T, few studies have examined the factor structure of the CLASS-T for use in Early Head Start (EHS) and subsidized child…

In Germany, there is still a great need for research on the quality of teacher-child interactions in ECEC institutions. Especially, because social interactions and relationships are crucial for (early) learning and development (Ulferts et al., 2019). However, there are hardly any results on factors influencing the interaction quality. This paper…

Research Findings: Evidence suggests that teachers are effective at improving the social and emotional readiness of low-income children. However, few measures are available to assess teachers' use of specific social-emotional practices within their classrooms. This paper compares an observational measure of teachers' social-emotional practices,…

Assistant teachers play an important role in Head Start and other early care and education (ECE) programs. This study found that assistant teachers contribute to classroom quality in the program's day-to-day implementation. Thirty-eight assistant-lead teaching teams from Head Start preschool classrooms across 14 Head Start centers within the…

The years from birth to five are critical for building the emergent literacy skills that precede learning to read and write. Early childhood education and care services are in a unique position to support emergent literacy development, particularly for children in socio-economically disadvantaged communities. This article reports the findings of a…

The purpose of this study was to examine the relationship between language skills and behavioural problems and the potential moderating role of the quality of classroom emotional support in this relationship among 242 preschool children from low-income families. The "Preschool Language Scale-5" was administered individually to each…

A large body of literature demonstrates that children who experience unstable housing and homelessness are at risk for developmental delays and social--emotional challenges. However, there is also evidence of variability in the functioning of these children. Our primary aims were to identify unique profiles among preschool-aged children who were…

Child-directed speech (CDS), which can help children learn new words, has been rigorously studied among infants and parents in home settings. Yet, far less is known about the CDS that teachers use in classrooms with toddlers and children's responses, an important question because many toddlers, particularly in high-need communities, attend…

Mathematics teachers' preteaching experiences as mathematics learners can affect their identity and practice in supporting their own students' learning and motivation in mathematics. However, little empirical data exist on teachers' formative experiences to guide these assumptions, particularly how teachers draw on these experiences when teaching,…

Policymakers, child care providers, and parents face tradeoffs in determining how much to spend on child care, including how many hours to purchase, and the features of programs that might influence quality. Given these tradeoffs, it is useful to understand what constitutes quality, the cost of care features associated with quality, the effects of…

The Head Start Act mandates that each Head Start recipient receive a monitoring review at least once every 3 years; each newly designated recipient be reviewed after the completion of its first year (and then at least once every 3 years thereafter); and all recipients that "fail to meet the standards" receive Follow-up reviews. Reviewers…

Research Findings: The increase in young Latino Dual Language Learners (DLLs) attending early care and education (ECE) programs has led to a focus on assessing classroom quality for DLLs, to evaluate the quality and impact of their early educational experiences. Experts have advocated for the use of multiple classroom observation tools (i.e.,…

The purpose of this cluster randomized group study was to investigate the effect of multitiered, dual-language instruction on children's oral language skills, including vocabulary, narrative retell, receptive and expressive language, and listening comprehension. The participants were 3- to 5-year-old children (n = 81) who were learning English and…

This secondary analysis explored longitudinal associations between the concentration of shared-language peers and the development of prosocial and problem behavior in dual language learning (DLL) preschoolers from low socioeconomic backgrounds. Mixed-effects regression models were used to analyze year-end outcomes of 212 Spanish-speaking students…

This is the second in a series of policy notes and related publications exploring prospects for developing indicators of teaching quality. The first examined federal databases that include information about teachers, demonstrating that almost none of the measures in these datasets provides indication of teaching quality. This policy note takes the…
