​Wallace’s Principal Pipeline Initiative generated eight reports from a wide-ranging research study; a follow-up report on sustainability, examining the status of the pipelines two years after the initiative ended; and an assessment of how the research for principal pipeline effectiveness stacks up against evidence requirements for federal funding under Title I and other parts of the Every Student Succeeds Act.
