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…

Dyslexia is a neurologically-based, lifelong condition that affects a person's ability to process language, which in turn can make reading and writing more difficult. Between 10 and 20 percent of all people are dyslexic. Providing appropriate reading instruction and intervention for young children by second grade could reduce the percentage of…

Third grade is a critical checkpoint in a child's educational journey. By the end of third grade, children need literacy skills that prepare them for increasing curriculum demands in fourth grade and beyond. Students who are not reading on grade level by this point are significantly more likely to drop out of high school or fail to graduate 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…

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.…

SREB states were among the first in the nation to set comprehensive state academic standards for K-12 schools. Setting these initial standards was only part of the job. Getting these standards right and keeping them right may be the most important task facing public education today. If state standards are too low, many public school graduates will…

This paper presents the appendices to the "High-Stakes Testing and Student Achievement: Problems for the No Child Left Behind Act" report. It contains the following appendices: (1) Example of Context for Assessing State-Level Stakes Sheet--Connecticut; (2) Example of Completed Rewards and Sanctions Worksheet--Connecticut; (3) Directions…

Under the federal No Child Left Behind Act of 2001 (NCLB), standardized test scores are the indicator used to hold schools and school districts accountable for student achievement. Each state is responsible for constructing an accountability system, attaching consequences--or stakes--for student performance. The theory of action implied by this…
