The study examined the relationship between implicit theories, goal orientations, subjective and test estimates of intelligence, academic self-concept, and achievement in a selective student population (N=300). There was no direct impact of implicit theories of intelligence and goal orientations on achievement. However, subjective evaluations of intelligence and academic self-concept had incremental predictive value over conventional intelligence when predicting achievement accounting for more than 50% of its variance. The obtained pattern of results is presented via structural equation models and interpreted within a dynamic regulative systems framework suggesting the importance of further studying complex sets of achievement predictors that include ability, personality and mediating constructs.
