With the growing popularity of competence testing, there is a need for more research on newly developed test instruments. Therefore, I investigated competence in biology for dimensionality with regard to concept and process knowledge and its relations to linguistic competencies, cognitive ability, grades and self-concept in biology, chemistry and physics. The structural equation analyses are based on 3 165 German tenth-graders. First, concurring models reveal the dimensional structure. Second, covariates are applied systematically to the dimensional model with the best fit. The results show that competence in biology consists of two highly correlated dimensions: concept and process knowledge. Besides the high relations with linguistic competencies and general cognitive ability with both biology dimensions, differential effects could be detected for concept knowledge which is stronger associated to linguistic competencies than to general cognitive ability. The relation to the covariates grades and academic self-concept is inconsistent. Concerning grades, none of the expected patterns were found. One’s self-concept in biology helps explain concept and process knowledge in biology whereas self-concept in chemistry and physics does not. This study shows that multidimensionality of competence in biology and other disciplines will need to be tested before implementation in assessment, teacher education and curricula.
