Theories of student engagement for dropout and school completion are proposed to begin as early as age five. Student engagement in elementary-age students has been linked to school completion, post-secondary education, and achievement. However, there is little research examining patterns and profiles of student engagement in this population. In an effort to provide more individualized support and intervention, work in the field of student engagement has begun to examine profiles of student engagement and disengagement or disaffection. This study explored the identification of distinguishable groups based on student engagement in a sample of third-grade students and those groups' associations with demographic and outcome variables. Consistent with findings of research with older students, four distinct profiles of student engagement were found for males and females: Engaged, Cognitively/Affectively Disengaged, Behaviorally Disengaged, Disaffected. An additional class characterized by high absences was found for males. Demographic characteristics were associated with cluster attributes for males (Free or Reduced Lunch, special education, English Learner, and race-ethnicity) and female (El status). Cluster affiliation was significantly associated with seventh grade Math and Language Arts grades for both males and females and absences for males. Implications and future directions for research are discussed. The findings from the current study indicate there are discernible classes of student engagement and disengagement that can be identified as early as the third grade. These results may aid in the early identification of those at risk for dropping out of school and more effectively link students to targeted early interventions.
