The YES-O was established through the Department Order No. 72, s. 2003 signed by DepEd Secretary Edilberto C. De Jesus.

The YES-O is a school-based co-curricular organization which served as a significant venue for students’ actions and movements toward safeguarding, promoting, and conserving the environment for future generations.

The YES-O is the only recognized co-curricular environment club or organization in the school and consolidates all other environmental and/or ecology clubs or organizations in school with main and primary programs or projects for the environment or ecology in the said organization.
