3DE’s multifaceted approach to learning uses case methodology to integrate the real world into the standard high school experience. This universally effective approach to learning is the anchor for interdisciplinary teaching, relevant connectivity, and authentic project-based application that is delivered in every 3DE school. The result is a high school experience that reflects the dynamic pace of activity and interconnectedness of life beyond the classroom walls.

3DE’s dedicated teachers set high expectations and foster a strong sense of community among their students. Year-over-year, the curriculum layers in defined competencies to continually build students’ skills and mindset as they advance from facilitated learning to self-directed. By the end of their four-year high school career, students graduate with the knowledge, skills and confidence to thrive after high school, whether they choose to go to college, join the workforce, open their own business, or join the military.

Learning where rigor meets the real-world:

  • Students participate in authentic project-based application that is integrated across all core classes

  • Students consistently engage with a variety of industries, professionals, and careers

  • Students develop valuable competencies to navigate a high-growth careers

  • Students identify career interests that fit their aptitude, interests, and aspirations 

  • Students gather information and support to navigate the post-secondary admissions & financial aid process

  • Students gain exclusive access to 3DE designated scholarships
