Overachievement

Overachievers are individuals who "perform better or achieve more success than expected." The implicit presumption is that the "overachiever" is achieving superior results through excessive effort. In a teaching context, an "overachiever" is an educational label applied to students, who perform better than their peers when normalized for the instructor's perceptions of background, intelligence or talent. In the workplace context, individuals who are deemed to be overachievers are those with the drive to complete tasks above and beyond expectations and who set very high career goals for themselves.
