Our Mission

CSS helps schools become places where students want to be.


We partner with schools in three areas: developing all students into leaders; empowering teachers to collaborate with each other and with students; and engaging entire school communities to improve how learning happens.

CSS’s impact can be seen in the experiences of 425,000 students across 500 schools. Our clients include schools and school districts in urban, suburban, and rural communities ranging from high-poverty to more affluent, including:

  • Delaware
  • Maryland
  • New Jersey
  • New York
  • North Carolina
  • Pennsylvania
  • Washington, DC
