This work shows the use of Structural Equations Modeling (SEM) methodology to validate the conceptual structure of context questionnaires employed in national and international studies that evaluate the educational achievement of students. Unfortunately, evaluation agencies do not assign the same amount of technical resources to context questionnaires as those allotted to achievement tests, consequently the former are rarely subject to validity studies. In order to show the use of SEM methodology, a questionnaire was selected, which was employed by the National Institute for the Evaluation of Education to investigate the background factors associated with educational achievement of elementary school students in the third grade. It was administered to a national representative sample of 55312 students. This questionnaire is analyzed according to SEM procedures of confirmatory factor analysis (CFA). The obtained results provide evidence for the constructive validity of this tool.Downloads
