GreenSchools Certification Requirements

PLT GreenSchools certification reflects  environmental education in the curriculum, student leadership, and environmental action.

In order to earn recognition as a Certified PLT GreenSchool, schools must demonstrate they:

  • Are incorporating environmental education across the curriculum,
  • Take students outdoors to learn,
  • Have established a Green Team of students, staff, and community members,
  • Have implemented one or more student-led action projects, 
  • Maintain state-mandated or recommended environmental standards, and
  • Have completed all five PLT GreenSchools Investigations.

Consistent with the PLT GreenSchools focus on sustainability, two certification tiers address the idea of continuous progress. The specific requirements for each tier are listed below. 

  • Certified PLT GreenSchools meet a set of criteria that demonstrate teacher professional development in environmental education, integration of environmental education into the curriculum, an active student-led Green Team that conducts investigations and takes action, and reporting and celebrating accomplishments.
  • Sustaining PLT GreenSchools demonstrate a sustained commitment to these criteria over two or more years.
