The Teacher Leadership & Collaboration (TLC) case studies are designed to bring the voices of distributive leadership to life as well as to illustrate how TLC can be designed to thrive in a variety of unique school settings. Each highlighted school has its own significant challenges and context but through exemplary practices of advance planning and foundation building; transparency and openness; investing in supporting structures; and dedication to support and development for teacher leaders, they have harnessed the TLC model to help dramatically improve the coaching teachers receive and the quality of instruction in the classroom.
