Mirko emphasises that universal design leadership must support teachers’ professional growth. Short workshops rarely change practice; sustained, mastery‑oriented feedback does. He introduces the 30‑Minute UDL Lesson Glows and Grows Feedback Protocol, which helps leaders and colleagues provide swift, constructive feedback on UDL lesson plans. The process celebrates strengths (“glows”), identifies areas for improvement (“grows”) and equips teachers with actionable next steps to enhance equity and inclusion.
