What is Project Learning Tree?

Project Learning Tree (PLT) is an award-winning environmental education program designed for teachers and other educators, parents, and community leaders working with youth from preschool through grade 12. PLT is managed by the Sustainable Forestry Initiative (SFI).



How Project Learning Tree Makes a Difference

  • PLT encourages students to improve their schools, homes, and neighborhoods based on what they learn in the classroom.
  • PLT provides educators with peer-reviewed, award-winning curriculum materials to engage students in learning about the environment.
  • More than 675,000 teachers have received training in Project Learning Tree since the program began in 1976, making PLT one of the most widely-used environmental education programs in the United States.
  • By teaching students how to think, not what to think, about complex environmental issues, PLT is helping young people learn the problem-solving skills they need to make informed choices about the environment. We are also helping to prepare a 21st-century workforce faced with increasingly complex environmental issues.

Educators agree that PLT is good for getting children outside and having fun while learning about the environment. They also agree that the curriculum materials are useful for teaching academic standards.
