Continuously responding to educator needs and advancing the field of language development

WIDA provides language development resources to those who support the academic success of multilingual learners. We offer a comprehensive, research-based system of language standards, assessments, professional learning and educator assistance. WIDA’s trusted resources are used by 42 domestic states and territories and approximately 500 international schools throughout the world.

Core programs within WIDA include:

  • WIDA Consortium – A U.S.-based collaborative group of 40 member states, territories and federal agencies
  • WIDA International School Consortium – A network of approximately 500 member schools
  • WIDA Early Years – A program to support multilingual children in early care and education (ECE) settings
  • WIDA Español – A program to support Spanish language development of multilingual learners, Grades K–12

WIDA is part of the University of Wisconsin–Madison, a top-five university in the field of education. WIDA is housed in the Wisconsin Center for Education Research (WCER), one of the first, largest, and most productive education research centers in the world. WCER has assisted scholars and practitioners to develop, submit, conduct and share grant-funded education research for more than 50 years.

Can Do Philosophy

At WIDA, we believe that everyone brings valuable resources to the education community. Children and youth who are linguistically and culturally diverse, bring a unique set of assets that have the potential to enrich the experiences of all learners and educators. Educators can draw on these assets for the benefit of both the learners themselves and for everyone in the community. By focusing on what language learners can do, we send a powerful message that children and youth from diverse linguistic and cultural backgrounds contribute to the vibrancy of our early childhood programs and K–12 schools.

WIDA’s story begins with the No Child Left Behind Act of 2001, which brought English language learners into the national spotlight. As a result of this change, WIDA was born in 2003, when an Enhanced Assessment Grant was awarded to the Wisconsin Department of Public Education, WIDA’s first home.

The name WIDA originally stood for the three states on the grant proposal: Wisconsin, Delaware and Arkansas. Today, the name WIDA has come to represent a community of member states, territories, federal agencies and international schools.

Funded by the grant, WIDA developed the 2004 WIDA English Language Proficiency Standards, which served as the basis for the ACCESS for ELLs test of English Language Proficiency. WIDA also created professional development workshops to support educators in the WIDA Consortium member states.

In 2006, WIDA moved to its current home at the University of Wisconsin–Madison, specifically within the Wisconsin Center for Education Research. At UW-Madison, WIDA has been able to expand and improve its comprehensive system of assessments and instructional support for educators and practitioners of multilingual learners.

Today, ACCESS for ELLs includes an online test. The ACCESS suite of offerings also includes Kindergarten ACCESS and Alternate ACCESS for students with significant cognitive disabilities. Additional assessments offered include WIDA Screener and WIDA MODEL.

The WIDA Consortium has grown from three states to 40 member states, territories and federal agencies. The impact of WIDA has also expanded globally, as approximately 500 schools are members of the WIDA International School Consortium.

WIDA has also expanded to support emergent multilingual children with its Early Years program, and Spanish language learners, grades K-12 with WIDA Español.
