Background: Ability grouping has resurged in U.S. schools despite long-standing debates over its consequences for educational equity. Proponents argue that it is the best response to variation in academic skills because it allows teachers to customize the content and pace of instruction to students' diverse needs. Critics answer that this practice…

"Learning A-Z" contracted with Empirical Education to study the effectiveness of "Raz-Plus" in Milwaukee Public Schools during the 2016-17 school year. "Raz-Plus" is a literacy program that includes leveled books, skills practice, and digital activities and assessments. This study focused on 3rd, 4th, and 5th grade…

Currently, one in five students in the United States is the child of immigrants, and by 2040 this ratio is projected to increase to one in three. Understanding these students' academic needs is a fundamental part of improving their performance in our nation's schools. Our study continues this research within a multilevel conceptual framework,…

The National Assessment of Educational Progress (NAEP), also known as the Nation's Report Card, is the largest nationally representative assessment of what students know about mathematics, reading, science, writing, the arts, civics, economics, geography, U.S. history, and technology and engineering. This fact sheet reports only the reading and…

Background: Research has suggested that one of the most important variables for the development of reading comprehension is the home literacy environment, composed of the literacy interface and what is known as the limiting environment. The current study investigated Spanish children's reading comprehension in relation to these two dimensions.…

This study examined the effectiveness of the intensive implementation of a multicomponent reading intervention (Voyager Passport) with 306 fourth grade students with severe reading difficulties. Students with reading comprehension achievement below the 15%ile in the fall of fourth grade were randomly assigned to the intensive intervention or to…

In our report, "Learning during COVID-19: Initial findings on students' reading and math achievement and growth," we examine how school shutdowns impacted student achievement at the start of the 2020-21 school year. Using data from schools all over the country, we've built these visualizations to explore three key questions: (1) How have…

Up until 2020, National Assessment of Educational Progress (NAEP) reading scores had increased only slightly since the early 1990s with large achievement gaps for students of color and students living in poverty. Modest gains in fourth grade reading proficiency since 1992 were erased during the pandemic. The insufficient progress in reading even…

Recognizing the limitations of the existing frameworks and models applied to estimate the learning loss caused by COVID-19 across the world by different studies, and the urgent need for estimating such loss at the different education levels, this paper, employs the Education Value Chain Analysis ( EVCA) approach as a new paradigm, attempts to…

This paper is the first to examine the longitudinal results of six years of implementation of Literacy Squared, a biliteracy model for Spanish/English speaking emerging bilingual students. This model includes paired literacy instruction with grade-specific time allocations for Spanish literacy and literacy-based ELD. Furthermore, cross-language…

We used survey and administrative data from Washington State to assess the degree to which special education teacher preparation, district literacy instructional practices, and the alignment between preparation and practice were associated with the reading test score gains of students with high-incidence disabilities taught by early-career special…

In this paper, we use NWEA MAP test data to examine variation in students' achievement and growth during the pandemic across multiple dimensions. Consistent with prior evidence, we find that students' test scores in fall 2021, on average, were substantially below historic averages. Moreover, the average scores of students of color, students…

Students with early indicators of behavior risk have predictable, negative outcomes, and those with co-existing academic problems have significantly more negative outcomes. Identifying academic subclasses of students with behavior risk can inform integrated interventions and school-based problem-solving teams. In addition, identifying academic…

The present study attempted to extend our knowledge of the role of reading fluency in contributing to reading comprehension among Turkish students in grades 4 through 8. One hundred students at each grade level were administered assessments of reading fluency, word recognition automaticity and prosody, and silent reading comprehension. Word…

This study compared the summer learning rates of students who attended Houston Independent School District (HISD) 2016 summer school to similar students who did not attend, for both promoted and retained students. For students between 1st and 2nd grade and those between 2nd and 3rd grade, summer learning rates were faster for both promoted and…
