We examined how children (N = 448) with separate or co-occurring developmental language disorder (DLD) and dyslexia performed on school-based measures of academic functioning between second and fourth grades. Children were recruited from 1 school district in the U.S. state of South Carolina via classroom screenings and met common research criteria…

South Carolina's public education system is broken. For the past several years, the State of South Carolina and the nation have somehow managed to do the nearly impossible. Both have produced more English Language Learning (ELL) students to be proficient in English Language Arts (ELA) (i.e., reading, writing, and usage) than native English…

The primary aims of this study were two-fold: (1) to describe average change in the written narrative performance of second grade students from the fall and spring of the school year; and (2) examine patterns of individual growth to test for Matthew effects. Participants included 299 children in second grade. Microstructural measures were derived…

We use data from oral reading fluency (ORF) assessments to examine COVID-19's effects on children's ORF in over 100 U.S. school districts. Students' development of ORF largely stopped in spring 2020 following the onset of the COVID-19 pandemic. In fall 2020, students' gains in reading were stronger and similar to prepandemic rates. However, fall…

Although research related to the Science of Reading has documented the positive effects of explicit, systematic reading instruction for all students, students from historically marginalized groups often experience differential opportunities to learn and are likely to perform lower than their peers on large scale measures of reading achievement.…

Education has faced unprecedented disruption during the COVID-19 pandemic; evidence about the subsequent effect on children is of crucial importance. We use data from an oral reading fluency (ORF) assessment--a rapid assessment taking only a few minutes that measures a fundamental reading skill--to examine COVID's effects on children's reading…

This is the technical index for the research brief "Education's Long COVID: 2022-23 Achievement Data Reveal Stalled Progress toward Pandemic Recovery." Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also…

This study found that as early as the beginning of kindergarten and before any formal schooling began for most students, the achievement gap already existed. It was mostly related to students' poverty, ELL status, and SWD status, as well as to schools' having larger proportions of economically disadvantaged students. Students from poor families…

The Matthew effect, where good readers get increasingly better over time compared to relatively lower-ability readers, is an often cited phenomenon in reading research. However, researchers have not always found empirical evidence supporting a Matthew effect. We used hierarchical growth curve modeling to test for the presence of the Matthew effect…

Summer loss of reading is a potential factor in maintaining, and potentially widening, the achievement gap. This study used curriculum-based measurement of reading (R-CBM) to investigate the effect of the summer on reading. For this study, 317 students in Grades 2 to 5 were assessed in the spring and fall using Dynamic Indicators of Basic Early…

Studies illustrate that achievement gaps between poor and non-poor children already exist at kindergarten (Lee & Burkham, 2002). The larger the gap at the time children enter school, the harder it is to close the gap. This article reviews a case study of one Midwest school district and their attempt at reducing the achievement gap through the…

This design experiment addresses the question: How can second-grade students from low-SES schools attain the same levels of achievement as students from high-SES schools on standards-based social studies and content area literacy assessments? Students from two high-SES school districts were assessed in order to establish target levels of…

Five years of reading comprehension data in Florida Reading First schools were analyzed to address questions regarding student improvement, reduction in the achievement gap, efficacy of site visits to schools making no achievement gains, and effects of student mobility on growth in reading comprehension. Participants were 120,000 students (about…

On September 23, 2008, Latino state legislators from throughout the United States participated in a Legislative Hearing on Pre-K and the Early Grades on Capitol Hill. The nation's leading experts on Latinos and early childhood education presented new research and information on programs and policies that work. Their testimony provided an in-depth…
