The issue of missing data raises concerns in all statistical and educational research. In this study, we focus on missing data in school-based assessment data generated by progressed high school learners (those who did not meet the promotional requirements for their current grades but were allowed to move to the next grade because of policy…

Grade retention, the practice of holding a student back in the same grade, has been a controversial topic in the United States for decades. English learners, a growing population in US schools, are consistently identified for grade retention more often than their English-only counterparts. The purpose of this study is to test the impact of grade…

We use longitudinal data on all high school students in Washington State, including postsecondary education and workforce outcomes, to investigate predictors of intermediate and postsecondary outcomes for students with disabilities. We pay particular attention to career and technical education (CTE) enrollment and the extent of inclusion in…

In addition to intrapersonal developmental changes that middle-school students experience, they also…

Students in the United States change schools often, and frequent changes are associated with poor outcomes along numerous dimensions. These moves occur for many reasons, including both promotional transitions between educational levels and nonpromotional moves. Promotional student mobility is less likely than nonpromotional mobility to suffer from…

How many students repeat a grade each year? How do retention rates vary across states and over time? Despite extensive research on the predictors and consequences of grade retention, there is no systematic way to quantify state-level retention rates; even national estimates rely on imperfect proxy measures. We present a conceptually simple…

High school dropout, enrollment, and graduation rates are important indicators of students' college and career readiness, which in turn significantly impact both individual income levels and the overall knowledge-driven economy. Despite the long-term benefits of a high school education, much of the current literature on raising school…

What distinguishes high schools that "beat the odds" for students from traditionally lower-performing groups from schools that struggle to improve the achievement and graduation rates of these student populations? What types of programs, practices, and processes support better than expected outcomes for students at risk of failure? How…
