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 report looks at student growth in Arkansas school districts disaggregated by district poverty and by the district's value-added performance relative to other districts. We estimated district value-added performance statistics by subject and grade level (8 and 11-12) for longitudinal student cohorts, using statistical models that adjusted for…

Exit rates from Limited English Proficiency (LEP) for students who enter the Wake County Public School System (WCPSS) as LEP students vary by when students enter WCPSS (based on students entering in kindergarten, grade 6 or 7, or grade 9). Based on our 2008-09 cohorts, students entering in grades 6 or 7 were most likely to exit LEP status after…

In this technical report, we present the results of a reliability study of the sixth-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

Extending the school day through programs that will supplement core courses, such as offering intensive, after-school tutoring or small-group study sessions in reading and mathematics, is one method districts use to boost school performance and narrow educational achievement gaps between students of different racial and economic backgrounds (Redd…
