Six large school districts have been participating since 2011 in The Wallace Foundation’s Principal Pipeline Initiative, a six-year effort to train, hire and support talented principals. In this series of eight videos, the superintendents of these districts discuss details of their effort, lessons they have learned and advice they can offer to other districts. Many of the experiences they recount are detailed in a January 2015 report about the initiative, one in a series by independent researchers evaluating the effort.
