Despite a growing research base on the need for and value of instructionally-focused principal supervisors, few states have addressed principal supervisors in their plans to implement the Every Student Succeeds Act (ESSA). In those plans that include strategies pertaining to principal supervisors, there is limited detail. This resource highlights the work of a state--Minnesota--that is building such a strategy, providing insights on why and how state leaders are integrating principal supervisor investments into their education agenda. Further, it offers specific recommendations and select resources state officials can use to strengthen how principal supervisors are included in their states' overarching vision for outstanding, equitable leadership and their specific plans for ensuring every school is led by well-prepared, well-supported leaders.
