It’s no secret that high-performing leadership is synonymous with private-sector success. Nor is there any shortage of research into the leadership qualities that matter most, their potential impact on financial performance, and the importance of investments in leadership development. But what about leadership quality and development in the fast-growing social sector?

The US social sector—with more than one million nonprofit organizations addressing issues from education to the environment, from homelessness to digital literacy and access, arts and culture, and workforce development—accounts for nearly $837 billion in products and services, or 5.6 percent of GDP, according to the Urban Institute. Social enterprises, B Corporations, and other commercial organizations looking to do well and do good add to these numbers and represent an expanding segment of the overall social sector.
