Universal Design (UD) is a process that creates products and environments usable by people with diverse abilities. UD applies to curriculum, instruction, career services, multimedia, tutoring centers, web pages, appliances, and buildings. The UD process identifies the application, defines potential users, involves consumers, applies guidelines, plans for accommodations, trains involved parties, and evaluates. UD principles include equitable use, flexibility, simple and intuitive use, perceptible information, tolerance for error, low physical effort, and appropriate size and space. UD in education ensures diverse students are not marginalized by mainstream guidelines through designing flexible, universally-designed learning experiences that appeal to all learners.
