Molly Lynch and Linda Squiers talk with Helen Osborne about:

Intellectual developmental disabilities (IDD) and extreme low literacy (ELL). Why it is important to create materials specific to this audience.
Creating these materials goes beyond plain language. It also includes using evidence-based best practices that focus on behaviors, sentences, words and numbers, text layout, and visuals.
Information about a guide to help you develop materials and a tool to check how well your materials follow these guidelines.
