Implementation science—the study of the uptake, scale, and sustainability of social programs—has failed to advance strategies to address equity. This collection of articles reviews case studies and articulates lessons for incorporating the knowledge and leadership of marginalized communities into the policies and practices intended to serve them.

There are two other articles in the supplement by the same authors:

• Equity is Fundamental to Implementation Science
• Equitable Implementation at Work
