Essential Action Lever Support (EALS) is a program through which training and support is provided to principals, their instructional leadership teams, and principal supervisors to build capacity for creating and implementing systems for foundational instructional leadership practices. Following each cycle of professional development, principals receive implementation support, one-on-one coaching, and ongoing feedback. Throughout an EALS engagement, principals and their principal supervisors are provided opportunities to collaborate on their progress related to EALS and plan for sustained implementation.
