This report ​examines English learner testing, proficiency, and growth in the years surrounding the COVID-19 pandemic. This research builds on an October 2021 report on the impact of the pandemic, and includes data from the 2021-22 ACCESS for ELLs test administration. Findings indicate that in some grades and language domains EL's average proficiency and growth have returned to pre-pandemic levels. However, for most grades and language domains the evidence points to a continuing impact of COVID-19 on English learners’ English language development.

This study examined the extent English learners (ELs) in grades 1-12 with and without disabilities activated universal tools during an online English language proficiency assessment. Findings show that ELs activated the Line Guide, Highlighter and Magnifier more frequently than others. A significantly higher percentage of ELs with disabilities activated the tools than ELs without disabilities, but effect sizes were small.

​This Focus Bulletin illustrates how teachers and students can use language development portfolios to interpret and document language growth. The bulletin follows the story of how a grade-level team introduced portfolios to their practice, posing several questions the team asked as they refined their usage. It closes by offering two sample tools that teachers can use and adapt to capture multilingual learners’ language growth using modified Proficiency Level Descriptors (PLDs) from the WIDA English Language Development Framework, 2020 Edition.

This Focus Bulletin reframes the WIDA Can Do Philosophy as a can do cycle of actions that can be embedded into teaching and learning experiences throughout the entire school year. In it, we offer resource banks of questions that can be used to elicit student assets and reflect on ways to build on student assets at the beginning of each unit, during each unit, and at the end of each unit.

In this Focus Bulletin, we aim to help readers better understand how WIDA MODEL test scores may be used to support instructional planning decisions for multilingual learners and their teachers. We describe the rich resources available from WIDA to help educators understand what the test scores mean. We also explain how these resources may be used, along with MODEL test scores to help inform where multilingual learners have opportunities to further develop their English language skills.

This article provides an illustrative example of how the thinking of a consortium of United States states, territories and federal agencies has evolved in its conceptualization of language standards frameworks, working in tandem with the development of language assessment to ensure robust alignment between the two. It attempts to lay out the interrelated developments in WIDA’s English language development standards and its large-scale assessment over the course of close to 20 years.

This study describes long-term trends in students’ academic performance, documenting persistent and systematic disparities in academic outcomes across several student subgroups. Results corroborate emerging evidence from the field that English learner students, students with disabilities, and especially students who are learning English with a disability, are being consistently underserved by the U.S. educational system.

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.
