what we do

"CELF has an approach that works.  It works with the quirks of systems and schools.  It works with the readiness of the teachers and kids and with the willingness of the administration and the community.”

Scarsdale School District
Scarsdale, NY

CELF’s approach transforms learning into an authentic exploration of real-world problems, centered in and around the school community.



Working with school districts and educational organizations, CELF creates custom programming that addresses whole school change.  Using a proven framework, strategically developed to incorporate Next Generation Science Standards and current K-12 best practices, CELF provides educators with project-and place-based learning strategies and curricular access points for Education for Sustainability (EfS).  

Our professional learning model engages educators in interactive learning experiences,  with CELF Facilitators working side-by-side to design curricula and school programs that integrate EfS instructional practices and the “Big Ideas of Sustainability”, creating EfS classroom and school-wide learning opportunities.

Applying  community-building principles of EfS in every aspect of our work, CELF creates a learning community among students, teachers, administrators and the community at large.   When teachers belong to an effective culture of collaboration and cooperation, they are inspired to create this culture with their students.

The concepts of sustainability are universal, but every district and school starts from a different place. Whether you have a handful of knowledgeable teachers or one enthusiastic administrator, CELF will partner with you and your school or district, navigating the steps necessary to ensure today’s students will become tomorrow’s Earth Citizens.
