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…

Future Forward (FF) is an early elementary literacy program that pairs one-on-one tutoring with parent engagement. In 2017, Education Analytics (EA) received an Education Innovation and Research (EIR) Mid-Phase grant to expand FF to 14 schools in seven school districts across three states. The randomized control trial (RCT) study of the 2019-20 FF…

Background: Efficacy trials in education often possess a motivating theory of change: how and why should the desired improvement in outcomes occur as a consequence of the intervention? In scenarios with repeated measurements, certain subgroups may be more or less likely to manifest a treatment effect; the theory of change (TOC) provides guidance…

Background/Context: In 2010, Reading Recovery was awarded a $55 million Investing in Innovation (i3) grant from the U.S. Department of Education. This five-year grant supported the expansion of Reading Recovery in more than 1,400 schools in over 30 states, and provided intervention to over 80,000 students. Although a multi-site randomized…

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…

Countries in Latin America and the Caribbean have made progress in increasing primary school enrollment and completion among the very poor. However, challenges in improving reading persist. This study contributes to the evidence base on what works to improve early-grade reading skills by evaluating an early reading program implemented in two…

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…

Reading skills are the key building blocks of a child's formal education. Yet, the national statistics on literacy attainment are profoundly distressing: two out of three American fourth graders are reading below grade level and almost one third of children nationwide lack even basic reading skills. This study reports on an evaluation of the…

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 purpose of this report is to present the results of a two-year randomized control trial evaluation of the SPARK literacy program. SPARK is an early grade literacy program developed by Boys & Girls Clubs of Greater Milwaukee. In 2010, SPARK was awarded an Investing in Innovation (i3) Department of Education grant to further develop the…

This study addresses the effectiveness of a nationally used core reading program that reflects the research-based practices recommended by the National Reading Panel. This and other similar programs are increasingly used to prevent reading difficulties and ensure that all children are reading at or above grade level by the end of third grade. The…

The Fidelity of Implementation (FOI) study that is the focus of this report was conducted as a component of a scale-up effectiveness trial of the SRA/McGraw-Hill Open Court Reading program. The overall purpose of the FOI study was to support and provide context for findings from the larger experimental impact study of Open Court Reading (OCR). To…

This study addresses the effectiveness of a widely used core reading program that reflects the research-based practices recommended by the National Reading Panel. This and other similar programs are increasingly used to prevent reading difficulties and ensure that all children are reading at or above grade level by the end of third grade.…

The roughly one-quarter of U.S. eighth graders who score below basic on national assessments of reading are poorly equipped for the reading demands of secondary school. They struggle with summarizing and making text-based inferences (NCES, 2013). Intervention in middle school needs to be comprehensive, both because of the heterogeneity of the…

While there has been some increasing interest in external validity, most work to this point has been in assessing the similarity of a randomized trial sample and a population of interest (e.g., Stuart et al., 2010; Tipton, 2011). The goal of this research is to calculate empirical estimates of the external validity bias in educational intervention…
