Marshall Leadership Institute

“If you want to go fast, go alone. If you want to go far, go together.”

Transformative Leaders for All Schools

The Marshall Leadership Institute is dedicated to rethinking and redesigning how we identify, develop, and support powerful school leaders. Our programs—Leadership Fellows, New Leaders Fellowship, and Experienced Leaders Fellowship—develop highly prepared K-12 school leaders in collaborative, diverse cohorts so we can learn from each other and go far together.

Leadership Fellows Overview

America needs leaders who can transform schools. It starts with educators who are willing to transform themselves and their teams. It starts with you.

Leadership Fellows is a free, cohort-based program for experienced teachers and early-career administrators looking to deepen their leadership skills. Our fellows meet on Saturdays to develop essential school leader skills and habits through problem-based learning projects, authentic discussions, simulations, and reflections. By the end of this program, you will have the foundations to navigate the challenging and complex work of entry-level school leaders alongside a robust network of passionate colleagues.

Leadership Fellows is by far one of the best decisions I have made to build upon the growth mindset I push myself to have. Collaborating with educators from different parts of the country on different pages in their educational careers brings so much insight and wisdom.

Whole group discussion with leadership practice and feedback is an integral part of growing, but the most beautiful part of each session is the love and support you see the group giving to each other. The commitment is small in comparison to the invaluable knowledge gained that will last throughout your education career.

About the Marshall Leadership Institute

The Marshall Leadership Institute develops high-quality, scalable solutions to local and national challenges in school leadership.

  • High-quality preparation: Only 49% of districts and CMOs report being satisfied with their current candidate pool.
  • Diversity: Our principal workforce doesn’t demographically reflect the students our country serves. 78% of school principals are white and serve an increasingly diverse student body within their schools.
  • Retention: 1 out of 5 principals leave their role every year.

Our leadership programs are designed to address these challenges by mirroring the experience of school leaders in a supportive environment. We develop fellowships to support aspiring and current school leaders at every stage of their development.

Our flagship program, Leadership Fellows, began at Summit Public Schools. For over a decade, fellows consistently served as a pipeline into school administration and network leadership roles within Summit. Marshall began operating the Leadership Fellows Program in 2019-20 and has transformed it from a generalized leadership program into one that explicitly prepares candidates to join and be successful in entry-level school-site leadership roles.
