The current meta-analysis compares the self-concepts and perceived competencies of gifted and non-gifted students. Using meta-analytic methods to synthesise the results of 40 studies, we found that gifted students scored significantly higher than non-gifted students on measures of academic and behavioural perceived competence, as well as global self-concept. Gifted students scored significantly lower than non-gifted students on measures of appearance and athletic perceived competence. Significant heterogeneity was found in the extent to which gifted and non-gifted students' scores differed in the academic and global domains. Moderator variables such as participant grade level, method of gifted designation and publication year accounted for systematic differences in these domains. Gifted students' appearance and athletic perceived competencies may benefit from specific intervention, but their beliefs in other areas remain positive.
