The purpose of this WIDA Focus Bulletin is to provide guidance to teachers of English language arts (ELA) who are implementing the Common Core State Standards (CCSS) and working to respond to the specific needs of ELLs. In their treatment of academic language (or the language of school), the CCSS represent a departure from existing content standards.

Regardless of the growth model, aggregate test-score-based models of student growth require large and longitudinally connected samples of student data. When sample sizes are small it becomes impossible to reliably estimate and disentangle district, school and teacher effects from student growth data.

This study examines how 476 K–12 educators in 35 U.S. states identify and place English learners in language instruction educational programs. Findings reveal information about these educators, the instruments and information sources they use for decision making, and their perceived appropriateness of the decisions. Results provide practical implications for improving the English learner identification and placement decision at the district and school levels.

This research report provides a description of a study examining school districts in the WIDA Consortium whose English language learners (ELLs) exhibit consistently high growth on the ACCESS for ELLs (ACCESS) assessment.

This report examines English learners’ (EL) testing, proficiency and growth in the academic years of 2018–19, 2019–20 and 2020–21, using population-level data from ACCESS for ELLs Online, administered across the WIDA Consortium to students identified as ELs. The objective of the report is to shed light on the impact of the COVID-19 pandemic on ELs’ educational outcomes.

Motivated by findings of a 2018 WIDA report pointing to large overlap between ELs with Individualized Education Program (IEP) designations and those ELs who could be identified as LTELs, this study further focuses on these dual-identified students. Grouping ELs by ever-IEP (i.e., being assigned an IEP at any point in the longitudinal record) and never-IEP status, we compare these two subgroups’ English language growth trajectories across time. Our findings show consistent trends of differential growth and reclassification rates for these two subgroups.

The goal of the analyses presented here is to identify a procedure for creating alternate composite scores on English language proficiency assessments without using all four domain test scores (i.e., listening, speaking, reading and writing).

This study examines oral language development of 14 dual language learners ages 2.5 to 5.5 years in preschools in the Midwestern United States. They engaged in five key language uses: argue, explain, heuristic, recount, and request. Preschoolers 2.5 to 3.5 years only made simple requests or argued to meet their needs; the older cohort demonstrated a wider range of key language uses.

This report examines how Alternate ACCESS for ELLs serves as a tool that identifies English proficiency attainment for English learners with significant cognitive disabilities.

This report describes a study that examined to what extent scores on WIDA Screener predict scores on ACCESS for ELLs. Researchers found that Screener scores are strongly predictive of ACCESS scores, even when a variety of individual factors are accounted for.
