Background: Dyslexia is a specific reading disability characterized by word recognition difficulties that can qualify a student for special education services under the "Individuals with Disabilities Education Act" (IDEA; 2004; Yudin, 2015). As of 2024, 49 US states have legislation defining dyslexia and enumerating for schools…

Background/Context: Students classified as Long-Term English Learners (LTELs) are those who have not gained fluency in the English language, even after being enrolled in the U.S. K-12 educational system for five to seven years (Olsen, 2014). Although LTELs are not consistently tracked across states, we know they constitute a sizeable portion of…

Background: Early-grade reading proficiency is well documented as in important factor for later academic success. Researchers and educators consider the achievement of reading proficiency by the end of grade three to be crucial to future academic success and financial independence (Hein et al., 2013; La Paro & Pianta, 2000; Singh, 2013). As…

Background/Context: Previous research in educational assessment has consistently emphasized the importance of reliability as a cornerstone of test quality. Traditional measures of reliability, such as test-retest and split-half reliability, offer a broad view of how internally consistent a measure is but overlook the variability in this internal…

Background: This paper estimates the causal effects of an intervention under the UK-funded Partnership for Learning for All in Nigeria (PLANE). PLANE is a seven-year (2021-2028) early literacy and numeracy program that aims to improve student outcomes in Northwest Nigeria. In this region, fewer than 28% of children and youth. Numerous factors…

Teacher turnover has adverse consequences for student achievement and imposes large financial costs for schools. Some have argued that high-stakes testing may lower teachers' satisfaction with their jobs and could be a major contributor to teacher attrition. This study uses data on individual students and teachers from Georgia's statewide…

Background/Context: Despite increasing school enrollment, significant literacy gaps persist in developing countries, with many children unable to read by age 10. This paper evaluates "M'ap Li Net Ale," a comprehensive intervention aimed at improving early-grade reading skills in Haiti, a context characterized by limited government…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Background/Context: Regression discontinuity (RD) designs are used for policy and program evaluation where subjects' eligibility into a program or policy is determined by whether an assignment variable (i.e., running variable) exceeds a pre-defined cutoff. Under a standard RD design with a continuous assignment variable, the average treatment…

Previous research has established two types of struggling readers: those who struggle with lower-level reading skills and those who struggle with higher-level reading skills (Cain & Oakhill, 2006; Perfetti, 2007). The latter group is commonly termed "poor comprehenders": readers who exhibit poor comprehension compared to peers with…

School districts across the United States have increasingly adopted information and communications technology (ICT) in an attempt to improve student achievement across a wide range of educational settings. This paper examines the impacts of Achieve3000, an early literacy program that differentiates non-fiction reading passages based on individual…

School districts are increasingly adopting technology-based resources in an attempt to improve student achievement. This paper reports the two-year results from randomized control trial of Achieve3000 in the Wake County Public School System (WCPSS) in Raleigh, North Carolina. Achieve3000 is an early literacy program that differentiates non-fiction…

Preschool reading readiness is an issue with growing interest. The preschool years provide an opportune time when reading difficulties are more easily altered through exposure to early literacy skills. This paper extends the authors' previous research by examining the kindergarten performance of a cohort of children from a multi-year research…

Nearly one-quarter of U.S. eighth graders score below basic on national assessments of reading (NCES, 2013) and are poorly equipped for the reading demands of secondary school. Struggling adolescent readers cannot summarize a simple passage, use context to determine word meanings, and have difficulties making text-based inferences. In addition,…

The idea of targeting reading instruction to profiles of students' strengths and weaknesses in component skills is central to teaching. However, these profiles are often based on unreliable descriptions of students' oral reading errors, text reading levels, or learning profiles. This research utilized latent profile analysis (LPA) to examine…
