Program accomplishments

  • AT TRILLIUM ACADEMY, OUR PROGRAM IS INTENTIONALLY DESIGNED TO SUPPORT THE UNIQUE STRENGTHS AND NEEDS OF TWICE-EXCEPTIONAL (2E) STUDENTS. THE CURRICULUM AND PROGRAMMING ARE BUILT ON THE INTERPLAY OF APPROPRIATELY CHALLENGING AND ENGAGING ACADEMICS, EXECUTIVE FUNCTION (EF) SKILLS, AND SOCIAL-EMOTIONAL LEARNING (SEL). EVERY CLASS INTEGRATES THESE THREE PILLARS IN A UNIFIED MANNER. EF AND SEL DEVELOPMENT PROVIDE THE FOUNDATION 2E STUDENTS NEED TO ENGAGE DEEPLY IN LEARNING, WHILE ACADEMIC CONTENT OFFERS THE ARENA TO PRACTICE AND REFINE THESE SKILLS. IN TURN, ACADEMIC SUCCESS REINFORCES CONFIDENCE AND RESILIENCE, FURTHER SUPPORTING SEL GROWTH AND EF DEVELOPMENT. THEY ARE MUTUALLY REINFORCING ELEMENTS THAT CREATE A WHOLE-CHILD LEARNING EXPERIENCE AND AN APPROACH ESPECIALLY VITAL FOR 2E LEARNERS.
