A Structural Model of Academic Performance, Socioeconomic Status, and Spearman's g

Abstract

The study of psychometric g, a focus of research in both educational and occupational settings, recently has been raised to new levels by advances in covariance structure modeling, which allows relations among observed and latent variables to be investigated. This type of modeling was applied to the study of psychometric g in relation to collegiate academic performance and socioeconomic status. The results showed that psychometric g accounted for a substantial proportion of the variance in academic performance. The addition of the socioeconomic latent variable into any of the covariance structure models did not improve fit.
