In this idea paper, Public Impact’s co-presidents, Emily Ayscue Hassel and Bryan C. Hassel, lay out a vision for how districts can reach dramatically more students with great principals, for much higher pay, within budget—giving principals a career path that keeps them connected to students and schools through Multi-School Leadership. The “leadership machine” is powered by teacher leadership: Accountable multi-classroom leaders co-lead instruction schoolwide with principals, and also earn more, and make it possible for great principals to extend their reach, too.
