DL2 supports school district central office leaders in transforming their central offices into powerful engines of educational equity—relentlessly ensuring high-quality teaching and deeper learning that centers, values, and elevates the success of students identifying as Black, Indigenous, Latinx, students of color, or living in low-income circumstances. We do so by helping district leaders: * Access rigorous research and the latest knowledge in the field about what central offices do when they support equitable teaching and learning, *Use that knowledge to design new central office systems likely to be successful in their settings, and *Lead the change process from a culturally responsive stance. We study their progress and generate lessons for our partner districts and the field.
