摘要:(1) Background: To improve academic performance and prevent dropouts, many studies have investigated the effects of non-intellective competencies on performance, and the effects of performance on school satisfaction. The aim of this study was to investigate the direct role of both non-intellective competencies and performance on school satisfaction at the same time. (2) Methods: The study involved 731 Italian students, attending three different high schools, who responded to the H-Comp Scale, a questionnaire assessing twelve different aspects of students’ skills, attitudes and motivations over the study, and the H-Sat Scale, a questionnaire assessing five different areas of school satisfaction. (3) Results: We found a strong role of non-intellective competencies on school satisfaction and a marginal role of academic performance, gender and the attended class, which reduced as students’ seniority increased. (4) Conclusions: This study showed that school satisfaction depends on students’ self-perception in terms of their study competencies and the motivations possessed more than their sole performance, suggesting that this helps students to improve their non-intellective competencies in order to increase their performance and reduce the risk of dropouts, both directly and indirectly, through increasing their school satisfaction.
