Service and leadership that maximize the success of all students

California Outdoor School Association


The California Outdoor School Association (COSA) is dedicated to ensuring that all students in California have the opportunity to participate in an outdoor school experience as delineated in California Education Code Sections 8760-8774.

COSA is dedicated to quality Residential Environmental Education for the students of California. Our purpose is to advocate for student participation in residential outdoor schools, enhance existing Outdoor School Programs and to help any Local Education Agency that does not already run a Residential Outdoor Science School to begin their own.

COSA is funded by a grant from the California Department of Education.

For more information contact the COSA Chairperson, Michael Olenchalk.
