The Crossroads School, during its formative years, worked with the nationally recognized organization Outward Bound in the creation of its instructional program. This curriculum model, known as Expeditionary Learning, is designed around long-term, in-depth investigations of a topic that engage students through authentic projects, fieldwork and service learning. The work students do within learning expeditions centers on rigorous academic achievement, critical thinking, essential skills and habits, personal development and high quality original work.
