This document discusses underachievement in gifted students. It defines underachievement as a discrepancy between ability and achievement, and may manifest as failing to complete assignments or disengaging from school. Underachievement needs to be a persistent problem, not just a short-term issue. Potential causes of underachievement include unchallenging classrooms, peer pressure, family dynamics, internal issues like depression or perfectionism, and deficits in self-regulation. Interventions focus on counseling to address personal and family issues, and instructional modifications to engage students through their interests. More research is still needed to fully understand the complex causes and develop effective prevention and intervention strategies.
