The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

The study examines the validity of four commonly used early numeracy curriculum-based measurement (EN-CBM) tools in relation to math criterion measures. Additionally, the investigation examines the reporting quality of the included studies as related to important features of assessing CBM's technical adequacy. For inclusion in the meta-analysis,…

The present study aimed to develop and validate a questionnaire assessing parents' beliefs about, and attitudes toward, supporting young children's English as a second/foreign language development -- Parent English Language Belief and Attitude Questionnaire (PELBA-Q). The PELBA-Q was piloted with 173 parents of kindergarten-aged children and…

In the US K-12 public school settings, each state's annual English language proficiency (ELP) assessment, as part of an educational accountability system, has tremendous impact on English learner (EL) students' academic paths and success. It is thus critical to establish a robust validation framework and empirical evidence to ensure that states'…

This manuscript presents the results from a study to investigate the technical characteristics of two versions of a number line assessment (NLA 0-20 and NLA 0-100). The sample consisted of 60 kindergarten and 46 first grade students. Both number line versions had sufficient alternate form and test-retest reliability. The NLA 0-20 had low and the…

Vocabulary skills are important for overall reading competence, but vocabulary assessment approaches that inform instructional decision-making and are sensitive to improvement are limited. This article describes a process for developing vocabulary measures designed to facilitate data-driven decision-making for kindergarten and first-grade students…

This study investigated the measurement of social emotional competence in low-income youth by assessing the validity of responses derived from the widely used, teacher-rated Devereux Student Strengths Assessment (DESSA). Based on the five-component social emotional learning model proposed by the Collaborative for Academic, Social, and Emotional…

The New Mexico Public Education Department developed the Kindergarten Observation Tool (KOT) as a multidimensional observational measure of students' knowledge and skills at kindergarten entry. The primary purpose of the KOT is to inform instruction, so that kindergarten teachers can use the information about their students' knowledge and skills…

This study aimed to extract the psychometric properties of a Jordanian version of the Parents Evaluation of Developmental Status: Developmental Milestones (PEDS:DM) to present a psycho-metrically reliable Arabic scale that benefits the Jordanian context as an effective childhood intervention scale. The validity of the scale was achieved in three…

Surveys of teacher preparation program (TPP) completers have become one widely used measure for program accountability and improvement, yet there is little evidence as to whether perceptions of preparation experiences predict the workforce outcomes of teachers. In the present study, we use statewide completer survey data from North Carolina to…

This study assessed the psychometric properties of a digital early mathematics assessment, the Ani Banani Math Test (ABMT) in three samples (N[subscript 1] = 243, N[subscript 2] = 691, N[subscript 3] = 1282) in kindergarten and first grade (age range 4.67-7.30). Confirmatory factor analyses showed that the ABMT appears to measure one general…

The purpose of this study was to investigate the relationship between the Penn Interactive Peer Play (PIPPS-HK) and the Preschool Play Behavior Scale (PPBS-HK) to establish concurrent validity of both scales. A total of 1,622 children age 3 to 6 and 152 teachers in 10 kindergartens (about 160 students and 15 teachers randomly selected from each…

This study investigated the dimensionality of bilingual phonological awareness (PA) in English and Spanish by replicating a kindergarten model in Grade 1, and presents alternatives to modeling clustered data. English and Spanish tasks were analyzed from previously collected samples totaling 1,586 first grade Spanish-speaking English learners. Four…

School districts across the United States increasingly use value-added models (VAMs) to evaluate teachers. In practice, VAMs typically rely on lagged test scores from the previous academic year, which necessarily conflate summer with school-year learning and potentially bias estimates of teacher effectiveness. We investigate the practical…
