IDL Guidelines: (modified from the National Center on UDL)
multiple means of representation: (recognition) presents information and content in many different ways, the “what” of learning
multiple means of engagement: (affective) supports a variety of ways for challenging, and motivating students, the “why” of learning
multiple means of action & expression: (strategic) allows many different ways of organizing, planning, performing, or expressing, the “how” of learning
adaptable accommodation strategies: design can be adapted to changing needs of specific contexts or individual learners, recognizes that some learners will not be fully included by design, builds in comprehensive awareness of and plans for accommodation strategies, materials and technology
IDL Principles
equitable use: design is equally useful and appealing to all, providing the same means of use for all (identical when possible, equivalent when not)
flexibility in use: design is adaptable to a wide range of contexts, individual preferences and abilities
perceptible information: design communicates necessary information effectively for a wide range of perceptual abilities and ambient conditions
simple & intuitive: design is easily understandable for a wide range of backgrounds, language skills, and concentration levels
tolerance for error: design minimizes adverse consequences of unintended actions, allows multiple attempts, or provides room for improvement
optional physical effort: design can be used efficiently and comfortably, allowing for a range of physical abilities
size and space for approach & use: appropriate size and space is provided for reach, manipulation, or use for a wide range of mobility
class climate: design is positive, promotes interaction and supports learning on a variety of levels
community of learners: design promotes purposeful collaboration and fosters meaningful learning
