The issue of high school dropout has long concerned policy makers, educational professionals, and the general public. In the gifted literature, this concern is no less pressing. Student engagement is becoming an increasingly discussed construct for conceptualizing the dropout phenomenon and designing appropriate interventions to prevent this phenomenon. The purpose of this literature review was to review prior findings in the gifted underachievement and dropout literature within the framework of student engagement. Specifically, academic, behavioral, affective, and cognitive indicators of student engagement are examined. Findings of the review and implications for research and practice are presented. Student engagement may prove to be an essential construct in understanding, predicting, and preventing dropout behavior among gifted students. (Contains 3 tables.)
