The purpose of this study is to illustrate the use of explanatory models based on Rasch measurement theory to detect systematic relationships between student and item characteristics and achievement differences using differential item functioning (DIF), differential group functioning (DGF), and differential person functioning (DPF) techniques. The major focus of the analyses in this study was to demonstrate a set of methodological techniques that can be used to better understand subgroup performance on a large-scale writing assessment, rather than to conduct bias or sensitivity reviews.

Summary of the report analysis and findings.
Research Brief. Using a 2004 sample of students who applied to at least one four-year college, this research brief finds that applying to more colleges causally increases students’ probabilities of enrolling in a four-year college, especially for those lower-income students applying to only one or two colleges.
Research brief. This brief presents information about the characteristics of the nation’s Hispanic-serving institutions (HSIs) and their students, as well as the HSIs’ contributions to the educational attainment of the Latino population.
Literature Brief. This brief gives an overview of the prevalence, causes, and consequences of college remediation, which aims to improve basic literacy skills among college students.
Research brief. This brief studies California's introduction of the Early Assessment Program to bridge the gap between K-12 educational standards and postsecondary education requirements, similar to the Common Core State Standards movement.
Literature Brief. This brief gives an overview of the prevalence, causes, and consequences of students' postsecondary choices.
Policy Brief. This brief examines the potential trade-off students face between the net price of attendance and the likelihood of completing a college degree when they make their postsecondary choices. The results suggest that students from low-income families could attend colleges where they have a substantially higher probability of completing a degree and face no increase in net price.
Research Brief. This brief examines variation across U.S. public high schools in students' postsecondary choices. The results indicate that some high schools are substantially more successful than others at guiding students to choose postsecondary alternatives that are well-aligned to their academic credentials.
Research Brief. This brief examines high school counselor staffing counts relative to four-year college enrollment rates. Recent evidence from a national survey of counselors provides support for claims by counselors and school administrators that current counselor staffing levels are suboptimal. An additional high school counselor is predicted to induce a 10 percentage point increase in four-year college enrollment.
