A series of confirmatory factor analyses using both LISREL VI (maximum likelihood method) and LISCOHP (weighted least squares method Ising covariance matrix based on polychoric correlations) and including cross-validation on independent samples were applied to items from the High School and Beyond data set to explore the measurement characteristics of a proposed let of academic self-concept measures. Results most strongly supported a first-order model with English Selr Ocmcept (ESC) and Math Self-Concept (MSC) as uncorrelated factors and General School Self-Concept as a factor correlating with ESC and MSC. Tests for invariance suggested that the model holds up across gender, but not across socioeconomic status. The results provide further confirmation (..: the independence of ESC and MSC and for the invariance of the structure of self-concept across gender, at least for adolescents. The possibility that the structure may differ across socioeconomic status deserves further consideration.
