In education, the details are the daily practices in every classroom and every office, what the teachers, leaders, and support staff do in their roles to pursue the school's goals.

The ultimate goal in school improvement is for the people associated with the school to drive its continuous improvement for the sake of their children and students. They do this by sharpening their practice and honing each specific practice every day.

This is called a practice-focused collaboration. This report describes what is a practice-focused collaboration.
