Project I4 is a federally funded SEED (Supporting Effective Educator Development) grant, a partnership between East Carolina University and the Institute for Educational Leadership. It is a cohort-based, yearlong professional learning experience aimed at reimagining instructional leadership through an equity lens. Specifically, school leader participants build capacity to document evidence-based, equitable academic discourse during classroom observations. To support this, they implemented a nested coaching structure, which creates a vital through line from coaches to school leaders to teachers to impact student outcomes. The model supports school leaders as instructional leaders to work more effectively with teachers in the context of their own schools with a focus on improving teachers' equitable classroom practices. Together, they cultivate stronger relational trust and identify opportunities for more equitable practices. Two interdependent principles guide their work: (1) nested coaching networks are essential; and (2) an equity focus is fundamental. Reform that sticks comes from the inside. The leadership actions that they cultivate through Project I4 are like the superglue of professional development: relational trust, nested coaching structures, evidence-based tools, and effective conversations. If school leaders work with teachers in their schools to address local concerns and engage in community learning exchange processes, they can build stronger internal capacity for change.
