Assess the educator's ability to apply UDL principles to adapt an existing lesson plan for students with diverse learning needs: identify learner barriers, revise learning objectives, and redesign materials and activities to provide multiple means of representation, action/expression, and engagement; specify formative and summative assessment adaptations, scaffolds and accommodations (including assistive technologies and language supports), and justify choices with UDL checkpoints and implementation considerations for a 45–60 minute lesson.
