In this dissertation, I examine how two major social programs in Kentucky--state-funded preK and Family Resource and Youth Service Centers--impact children's outcomes across the state, including racial, ethnic, and economic equity through elementary school. In each chapter, I will analyze how early childhood opportunities relate to outcomes…

The purpose of this work was to examine the effect of classroom teachers who earn certification as a National Board Certified Teacher (NBCT) by the National Board for Professional Teaching Standards on mathematics and reading achievement and behavioral outcomes (attendance and discipline referrals) for students in Grades 4 and 5. Two studies were…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

This brief examined the patterns of reading achievement using statewide data from all students (Grades 3-10) in multiple years to examine gaps based on student, school, and district characteristics. Results indicate reading achievement varied most between students within schools and that students' prior achievement was the strongest predictor of…

Northwest Evaluation Association™ (NWEA™) is committed to providing partners with useful tools to help make inferences from the Measures of Academic Progress® (MAP®) interim assessment scores. One important tool is the concordance table between MAP and state summative assessments. Concordance tables have been used for decades to relate scores on…

Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…

Intraclass correlations are used to summarize the variance decomposition in popula- tions with multilevel hierarchical structure. There has recently been considerable interest in estimating intraclass correlations from surveys or designed experiments to provide design parameters for planning future large-scale randomized experiments. The large…

Educators and policymakers have set a goal that all students graduate from high school ready for college and careers. A substantial body of research supports the idea that the path to college and career readiness begins well before middle and high school. In an earlier policy report, ACT examined the percentage of academically far off track…

This nonexperimental study explored the relationships among individual differences, contextual variables, and reading achievement of English language learners (ELLs) in one large urban school district in the United States. The sample comprised 840 students in Grades 3-8 and 10 nested within 37 schools. Hierarchical linear modeling results indicate…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

The primary purpose of this study was to determine if there was a difference between self-contained and departmentalized classroom organization on the Kentucky Core Content Test (KCCT) in reading and mathematics for students in fourth and fifth grade. A secondary purpose of this study was to consider how these organizational structures affect the…

Since the 2003-04 school year, Save the Children, U.S. Programs, has supported programming designed to improve reading skills among struggling students in rural areas. The literacy program includes both afterschool and in-school interventions with small groups of children. These are implemented by well-trained paraprofessionals and are designed to…
