The Seal of Biliteracy (SoBL) is a high school graduation credential that recognizes US students in their final year of high school who have demonstrated proficiency in English and at least one other language. SoBL implementation has been shown in many contexts to be governed by local policy arbiters, who interpret the state policy to provide…

Federal law requires states to develop systems to hold K-12 schools accountable for the outcomes of all students. This includes using data to illuminate how historically marginalized groups of students, including English Learners (ELs), are disadvantaged by systems that fail to meet their distinct needs. But for this to be useful for school…

The population of English learners (ELs) in K-12 schools continues to grow. Between the 2009-10 and 2014-15 school years, the percentage of English learners increased in over half of the states, and in 2017, English learners made up 10.1% of the total student population. Research suggests that in their transition to English, non-native speakers…

The call for more expansive access to bilingual education is grounded in a comprehensive synthesis of evidence on the benefits of bilingual education, bilingualism, and biliteracy for students and the larger social fabric. Many studies find that access to bilingual education programs has a medium to large positive impact on students' academic…

The Seal of Biliteracy (SoBL) is a language policy that has gained traction across the United States as stakeholders seek to recognize students' competencies in languages other than English. Despite its potential to enhance language proficiency and encourage participation in language education, the SoBL has been unevenly implemented, with…

The Migration Policy Institute has produced a set of fact sheets providing an overview of key characteristics of the foreign-born and English Learner (EL) populations in select states. It aims to build understanding of state demographic contexts, how ELs are performing in K-12 schools, and the basics of state policies for EL education under the…

In 2016, there were 4.9 million students identified as English language learners (ELLs) in U.S. public schools who undergo testing. Students identified as ELLs are allowed to use paperback bilingual dictionaries during testing as an accommodation. When deciding whether to provide the accommodation, teachers need to consider several factors. First,…

With the 2015 passage of the "Every Student Succeeds Act" (ESSA), the oversight of language policy in U.S. schools shifted from federal to state governance. Although the education of students officially designated as English learners (ELs) has historically been grounded in federal law, we argue that ELs' educational experiences are also…

Castañeda v. Pickard (1981) mandated that educational programs for emergent bilinguals be tested for program efficacy. Since English language development (ELD) curricular materials are one part of an instructional program, we assess this mandate by examining the effectiveness of ELD materials in Texas. Using local linear matching, we find that…

Across the United States, students face increasingly high expectations of what they should know and be able to do upon completing high school. However, too few state policies take into consideration how the pathway to graduation may look different for English Learners (ELs), particularly adolescent newcomers who have limited formal education. Many…

More than 7.4 million U.S. children ages 5 and under live in a household where a language other than English is spoken by a parent or caregiver. But despite the size and growth of this Dual Language Learner (DLL) population, and these children's distinct linguistic assets and learning needs, standardized policies for identifying them and…

The United States is becoming a more culturally and linguistically diverse nation. This is especially true when we look at the youngest generation of learners. This growing diversity increases the need to accurately identify young children as dual language learners (DLLs) prior to kindergarten. Ensuring educators have a strong understanding of…
