Research Findings: Measures of home child care (HCC) quality are limited and tend to be labor intensive. This article presents the measure development process as well as psychometric, construct, convergent and discriminant validity analyses for the HCC version of the Assessment for Quality Improvement (HCC-AQI) measure. The HCC-AQI is part of a…

Previous research suggests that the ways in which early childhood classrooms are organized may facilitate children's language learning. However, different measures of classroom organization often yield inconsistent findings regarding child outcomes. In this study, we investigated multiple aspects of classroom organization across two time points in…

Teachers' scaffolding behaviors support children's self-regulation skills in the classroom. However, little evidence is available regarding the presence of self-regulation scaffolding behaviors in preschool teachers, and how they vary throughout the year and in different learning experiences. Less is known about these behaviors in Latin American…

Research Findings: Despite widespread calls to advance equity in early childhood classrooms, there are few observational measures of equitable classroom processes that can be used for academic research or professional development for teachers. In this study, we investigate the psychometric properties of an observational measure of equitable…

Research Findings: The Quality of Care for Infants and Toddlers (QCIT) observational measure was designed to address the need for a valid and reliable measure of the quality of caregiver-child interactions that could be used in both center-based and family child care (FCC) settings, and with diverse populations. Results from a psychometric field…

Research Findings: A total of 54 videotaped mathematics activity observations drawn from 27 different pre-kindergarten classrooms in an urban public schools system in the U.S. were coded using 2 observational measures: (1) a general measure, the Classroom Assessment Scoring System (CLASS); and (2) a math-specific measure, the High Impact…

Quality rating and improvement systems (QRISs) are designed to assess, improve, and communicate the quality of early care and education programs. Using administrative data, we investigated whether providers that participated in a county-level QRIS saw increases to their global quality (tier) rating, domain-specific quality ratings, and scores on…

Many school districts face the empirical challenge of monitoring program quality to assure that all children experience pre-K environments that foster early learning and development. Factors that are exogenous to classrooms (such as evaluation timing) may play a role in estimates of program quality and yet are not fully understood. This paper…

Although writing is a critical foundational skill and teachers' approaches to writing is connected to development, writing instruction in preschool is often limited, infrequent, and narrow. While research has investigated literacy environments of preschool classrooms, often with a focus on reading, less is known about writing environments. Thus,…

Research Findings: The present study examined the extent to which instructional practices, including curriculum, in pre-K through third grade are vertically aligned. Attention was directed to teachers' grouping practices, academic content, and pedagogical methods given their importance for students' learning. Variable- and person-centered analyses…
