Two studies examined whether hope partially mediates the relationship between socioeconomic status (SES) and academic achievement. Guided by recent theoretical formulations about social class and the social cognitive process, in Study 1 a mediational pathway from SES to academic achievement via hope was documented in a diverse sample of adolescents. The mediational pathway was replicated in Study 2 in a minority sample of high school students. In both studies, hope was found to partially mediate the relationship between SES and grade point average. In addition, the unique contribution of hope to academic achievement replicated across the 2 studies, indicating that the additional stressors and challenges associated with being a minority did not affect the mediation. These results have implications for achievement gap interventions.
