The aim of the research described in this article was the development of an instrument to measure social emotional characteristics and special educational and pedagogical needs of students in the last grade of primary education. Questionnaires were developed for teachers as well as for students. Exploratory factor analyses showed that the factors underlying the structure of the teacher questionnaire corresponded for the larger part with the negative poles of four factors of the Big Five, i.e., conscientiousness, agreeableness, extraversion, and emotional stability. A stepwise regression analysis was conducted to examine which factors contribute to the prediction of type of secondary education. Intelligence was the most important predictor; lack of conscientiousness accounted for another nine percent of the variance in level of secondary education. (Contains 3 tables.)
