Marshall CoLab

Sparking Lasting Change

Marshall CoLab is dedicated to improving teaching and learning for students furthest from opportunity.


We bring together communities of educators, instructional coaches, and experts to co-develop and implement evidence-based practices and make them available to all schools.

Using the tools of continuous improvement – the science of getting better at getting better – we support educators along the path from theory to transformation to achieve lasting change.

Driven By Collaboration

Our approach is driven by collaborative partnerships with schools and districts across the country. We recognize that each school community context is unique. That’s why our work is guided by these principles.

  • We meet school teams where they are with the resources and partners to help educators reach their goals.
  • We help our partners close equity gaps and prepare all students for the future.
  • We prioritize relationships, which are essential to learning.
  • We believe that we can get better at getting better. Improvement science is in our DNA.
  • We commit to going far together and work with educators to develop their capacity to lead ongoing improvement.

A Message from the Director

Stephanie Lassalle

Director of Improvement Programs

“Schools can create inclusive, equitable learning environments where all students reach their full potential. To do that, we need to shift mindsets about what’s possible and redesign systems and practices in ways that center the needs of students furthest from opportunity. Our team of educators, coaches, and content experts is dedicated to partnering with school communities to bring this vision to life – and make it stick.”
