Charities with similar missions may operate in parallel but lack shared, validated yardsticks with which to assess their social impact and efficiency.

Considerable recent progress in healthcare performance measurement invites emulation. This paper examines these developments and how the nonprofit sector can adapt them to benchmark performance.
