Many studies have addressed the relationship of locus of control to gender, ethnicity, socioeconomic status and achievement. One area which has not received as much attention is the correlation of locus of control to the condition of being at-risk. Most research involving at-risk students has focused on identifying this group with in-school factors such as absenteeism, poor grades, learning disabilities, or behavior problems. This study not only proposes to verify previous research relating locus of control to gender and ethnicity, but also to confirm the findings that children considered at-risk have a greater tendency to have an external locus of control than their not at-risk peers. Such a conclusion would thus add a psychological dimension to the at-risk status. The results gathered from 114 fifth grade students revealed no significant relationship between locus of control and gender or ethnicity. A very significant relationship was observed between being at-risk and having a greater tendency toward an external locus of control. The implications of these findings to educators are discussed.
