50 Years of Project Learning Tree: Growing Together, Looking Forward

As we celebrate this milestone, one thing is abundantly clear: PLT’s greatest strength has always been its people. We all play different roles in building the world we want.

PLT’s story has never been about a single organization or resource. It is a story of people learning from one another, sharing what works, and building something greater together. These 50 years belong to all of us.
