ELSF’s research-informed guidelines support content developers in building their capacity to design, develop, and refine curriculum materials that effectively support multilingual learners. The English Language Development (ELD) Guidelines articulate key research-informed design features and fundamental aspects of language development that are the basis for improving designated ELD materials.

The Guidelines were developed iteratively with researchers, practitioners and experts. They are divided into five areas of focus. Each area is comprised of several guidelines that are explored in depth through specific attributes, providing content developers with actionable solutions to support multilingual learners.
