To estimate the long-term effects of the Reading Recovery® intervention, a regression discontinuity design (RD) was implemented in a randomly selected sample of Reading Recovery schools during each year of the federally-funded i3 Scale-Up external evaluation (2011-2015) and also in one additional cohort during the 2016-2017 school year. Long-term…

Despite policy relevance, longer-term evaluations of educational interventions are relatively rare. A common approach to this problem has been to rely on longitudinal research to determine targets for intervention by looking at the correlation between children's early skills (e.g., preschool numeracy) and medium-term outcomes (e.g., first-grade…

The case study from Brunei described in this report provides a practical example of how learning outcomes in this area can be improved through the power of teacher coaching. This report explores how the Literacy and Numeracy Coaching Programme (LNCP) -- developed by Brunei's Ministry of Education with technical assistance from the Education…

Background: Over the past two decades, national attention has emphasized the critical role of early literacy and language instruction in preventing reading difficulties and improved our understanding of how young children learn to read. The research has established that students who are not strong readers by Grade 3 are less likely to build…

The purpose of this study was to study the impact on student performance due to participation in the Catapult Learning Intervention program in the Mathematics and Reading services offered in a religious non-public school system in the Northeastern United States from grades 6-8. Student scaled scores from the NWEA MAP assessments administered at…

The goal of this study was to further evaluate the impact of IXL Math on math learning outcomes. Using a quasi-experimental design with matched treatment and control groups, this analysis utilized data from 312 public schools in Mississippi during the 2021-2022 school year. The middle school analysis included 272 schools (136 treatment, 136…

The Migrant Education Program (MEP) is authorized under Title I, Part C of Every Student Succeeds Act (ESSA) of 2015. Title I, Part C states that the purpose of the MEP is to assist states in their efforts to meet the special needs of migrant students by providing migratory children with the opportunity to meet the same challenging State content…

LXD Research conducted a third-party, mixed-methods efficacy study of 95 Percent Group's Phonics Core Program (95 PCP) to determine the program's impact on fourth and fifth grade students' literacy outcomes. Outcomes included Istation's Indicators of Progress (ISIP) Advanced Reading and the State of Texas Assessments of Readiness (STAAR). LXD…

The goal of this study was to further evaluate the impact of IXL on learning outcomes in math and ELA. Using a quasi-experimental design with matched treatment and control groups, we analyzed data from 296 public schools in Colorado during the 2018-2019 school year. The analysis of IXL Math included 186 schools (93 treatment, 93 control), and the…

Education policy debates over the last twenty years have focused on the need to increase students' test scores. The federal government and states have implemented and expanded a variety of test-based, school accountability policies. Accountability pressures have incentivized schools to narrow their curriculum, decrease time allocated to…

Since established by an Appropriations Act in 2006, the Teacher Incentive Fund (TIF) competitive grant program in the U.S. Department of Education (USDE) has supported human capital strategies "to ensure that students attending high-poverty schools have better access to effective teachers and principals, especially in hard-to-staff subject…

Reading Recovery is an example of a widely used early literacy intervention for struggling first-grade readers, with a research base demonstrating evidence of impact. With funding from the U.S. Department of Education's i3 program, researchers conducted a 4-year evaluation of the national scale-up of Reading Recovery. The evaluation included an…
