Who We Are

Creating Opportunities for Students to Thrive

Marshall Street Initiatives is a coalition of educators working to systematically improve opportunities for students across the country. Drawing from 15+ years of institutional knowledge at Summit Public Schools, we target locally felt, globally evident problems in America’s public education system so that every student has the opportunity to pursue a fulfilled life.

Our Approach

Marshall’s initiatives implement solutions to student learning challenges in K-12 education. Each initiative undergoes a rigorous four-step development process.

1. Define the Problem

We work with students, teachers, leaders, and parents across the country to define real challenges facing public education.

2. Generate Solutions

In partnership, we generate novel solutions and provide processes, expertise, infrastructure, and connections to vet potential solutions. 

3. Pilot Programs

In an effort to continuously improve, we pilot our solutions with schools and communities to learn and refine based on real-time feedback.

4. Establish Initiatives

Finally, we evolve the solution and spin off the established initiative when it has a strong growth trajectory and a route to financial sustainability.

This approach was refined through the Summit Learning Program which spun off in 2019 with nearly 400 school partners in 38 states and the District of Columbia.

A Message from the Director

Adam Carter

Adam Carter

Executive Director of Marshall Street Initiatives

Building an education system that serves all of our young people starts with redesigning K–12 schools — but it doesn’t end there. With Summit, we built schools around the needs of a student community. With Summit Learning, we engaged visionary educators across the country who enacted a vision of excellence for their schools. We’re now developing diverse teachers and school leaders, equipping parents with tools to prepare their children for lives of fulfillment, and expanding opportunities for students with disabilities. Marshall shares Summit’s spirit of innovation with others.

Our Impact

Marshall Street develops solutions to locally felt, globally evident problems in America’s public education system so that every student has the opportunity to pursue a fulfilled life. Learn more about our impact.
