The overarching goal of research at WIDA is to promote educational equity and academic achievement for multilingual students.

To achieve this goal, we work in partnership with districts, states and national experts to conduct research focused on understanding and explaining the educational experiences and outcomes of multilingual learners. Through our research, we also aim to inform the decision-making needs of educators and policymakers who serve these children and youth.

The WIDA research team is housed within the Wisconsin Center for Education Research (WCER). Located at the highly ranked School of Education at the University of Wisconsin–Madison, WCER is one of the first and most productive education research centers in the world.

Research Areas

Academic Language and Literacy

WIDA researchers study the ways students need to use language to meaningfully engage in school, community, and society. Research in this area focuses on developing, improving and implementing new instructional approaches and resources for multilingual learners and their teachers.


Our researchers are continually investigating multiple facets of assessments, including item and test design, accessibility features, the consequences of testing, as well as the psychometric properties of all WIDA assessments. Our team works closely with the Center for Applied Linguistics and Data Recognition Corporation, along with the WIDA Technical Advisory Committee.


Our researchers conduct research intended to guide practice and policy for promoting academic and social success among multilingual learners. This includes research focused on the design, implementation, and effects of programs and policies that affect multilingual learners. This team works closely with policymakers and practitioners at district and state levels to ensure that research results inform decision-making.

Technical Assistance 

Our researchers support the decision-making needs of states and districts. The technical assistance team carries out research that informs the decisions states need to make to comply with state and federal assessment and accountability policies. Our researchers work with states and districts to understand the implementation and outcomes of particular programs and to drive program improvement.


WIDA researchers share the results of their work through a variety of outlets. WIDA disseminates research findings nationally to policymakers, educators and researchers via WIDA bulletins, reports and briefs. WIDA researchers also contribute regularly to scholarly publications including journals and books.
