|WWC 2023001||Dual Language Programs Intervention Report
This What Works Clearinghouse (WWC) intervention report summarizes the research on dual language programs. Dual language programs can help native English speakers develop proficiency in a second language and English learners develop proficiency in both their native language and English. Typically, in dual language programs, classroom teachers instruct students from an early age and over multiple years in both English and a second language called the partner language. These programs vary widely by partner language, primary language of the student population, and duration. Most of the studies examined do not meet WWC standards. Based on the two studies that meet WWC standards, the WWC found moderate evidence that dual language programs positively impacted student literacy achievement in English compared with instructional programs in English only. The WWC found uncertain effects on science and mathematics achievement. More high-quality research is needed to understand the effects of dual language programs in varied contexts.

New Mexico is one of 48 states that offer a biliteracy seal to high school graduates to recognize their proficiency in a non-English language. The Regional Educational Laboratory Southwest English Learners Research Partnership collaborated with a large urban district in New Mexico to study the characteristics and college readiness of students who earn different types of biliteracy seals (state, district, and global seals) and whether earning a seal improves college outcomes. The study used data from three cohorts of students who graduated from high school in the district from 2017/18 to 2019/20. The study examined the characteristics and college readiness of students who earned different types of seals, the number of students who met some requirements for a seal but did not earn one, and the effect of earning a seal on college outcomes.
|REL 2017198||Home Language Survey Data Quality Self-Assessment
Most state departments of education across the U.S. require or recommend that districts use a home language survey as the first step in a multi-step process for identifying students who qualify for English learner student services. However, existing home language surveys may not reveal accurate information about students' language or students' exposure to English language and literacy and, therefore, can actually contribute to the misidentification of English learner students. In response to this challenge, Regional Educational Laboratory Northeast and Islands worked with state and district practitioners to develop the Home Language Survey Data Quality Self-Assessment Tool. This 15-minute self-assessment is designed for use by state leaders who coordinate programs to support students' English language acquisition and achievement in districts, as well as for district leaders who oversee the English learner student identification process in schools. The tool supports the collection of high-quality home language survey data by gathering information from district English learner student coordinators and prompts self-assessment of key practices that impact the quality of home language survey data. The report includes a guiding Data Quality Framework and presents the complete self-assessment tool along with description of how it was developed, how to adapt and administer the self-assessment, and how to engage stakeholders in analyzing and interpreting self-assessment results to identify opportunities for improvement. This engagement at both state and district levels will inform decisions that can contribute to the collection of more accurate data regarding English learner students.
