Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs. This forms a multidimensional regression discontinuity design (RDD) to analyze the effect of the educational treatment where there are two running variables…

Most English Learners (ELs)care reclassified as English proficient well before graduating from high school based on meeting multiple district-identified proficiency standards, an important achievement on the path to college access, completion, and success in the labor market. Many former ELs also meet separate benchmarks indicating readiness for…

The Every Student Succeeds Act requires that English Learners (ELs) are included in annual state testing (grades 3-8 and once in high school) and included in each state's accountability system disaggregated by subgroup to ensure that they receive the support they need to learn English, participate fully in their education experience, and graduate…

We investigated how high school mathematics course placement contributes to inequalities in college preparation for students categorized as "English Learners" (ELs), especially "long-term" English Learners (LTELs). We devised a base-2 enumeration approach that allowed us to process complex transcript data from one school…

Descriptive evidence shows that English learners (ELs) have lower high school graduation and 4-year-college attendance rates than monolingual and fluent English users. Applying the regression discontinuity design to rich administrative data from a large district in California, this study identifies the first causal effects of initial EL…

This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The…

The recent increase in the number of students classified as English language learners (ELLs) has focused significant attention on reclassification policy, which governs the process by which ELLs move toward, and are deemed to reach, full English proficiency. In this paper, we draw on a data set containing annual individual-level records for every…

This report examines the role of English learner (ELs) status in four-year college enrollment and bachelor's degree completion among Houston Independent School District (HISD) high school graduates. We divide students into four groups: students who are never classified as EL (hereafter referred to as "Never EL" students), ELs who are…

Using linked, individual-level data from a large metropolitan K-12 district and a large urban community college district in California, we examine whether indicators of college-readiness for graduating high school students who were initially classified as English Learners (ELs) are honored in community college course placement. In particular, we…

Guam is home to the largest population of migrants from the Freely Associated States (FAS): the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau. FAS students made up 22 percent of total student enrollment in Guam public schools in 2012. FAS students face a number of challenges when they enter Guam…

Recent policy changes in California's education system have opened up a unique opportunity to improve educational opportunities for the state's 1.4 million English learner students (ELs). The implementation of new state standards including new English Language Development standards will require major changes in teaching and learning for all…

The imperative that all students, including English learners (ELs), achieve high academic standards and have opportunities to participate in science, technology, engineering, and mathematics (STEM) learning has become even more urgent and complex given shifts in science and mathematics standards. As a group, these students are underrepresented in…

Research in the area of academic writing has demonstrated that writing varies significantly across disciplines and among genres within disciplines. Two important approaches to studying diversity in disciplinary academic writing have been the genre-based approach and the corpus-based approach. Genre studies have considered the situatedness of…

This report synthesizes findings from extant empirical research to identify nine key policy areas that state policymakers and stakeholders in California can leverage to improve English learners' (ELs') opportunities and outcomes across the state. Importantly, the report situates these policy areas within the current framework of California state…

The practical knowledge that enables good teaching has emerged over the past decade as an area of critical interest to educational researchers. This article reports on insights gathered during a series of teacher practical knowledge research projects that took place over a 10-year period with more than 40 teacher interns and experienced teachers.…
