The EcoSchools program is both a framework and a toolbox for taking action and engaging in environmental education. For students, the program provides opportunities for leadership, connection with classmates in different grade levels via peer-to-peer mentorship, and a way to learn about sustainability while having fun. For teachers, the EcoSchools program integrates seamlessly with curricula across Canada and offers unique opportunities for learning.

Each year, schools apply for certification by undertaking environmental actions, campaigns, and projects, and then recording them in the online EcoSchools Certification Application (ECA) to earn points. At the end of the year, school applications are assessed based on a standard established over 10 years of benchmarking and are awarded a final certification level.
