A STRUCTURAL MODEL OF ACADEMIC-PERFORMANCE, SOCIOECONOMIC-STATUS, ANDSPEARMANS-G

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