Perceived school climate and school grades in secondary school students: The mediating effect of self-determined motivation

Students’ perception of school climate plays an important role in the quality of their academic experience. However, the effects of perceived school climate on self-determined academic motivation (Ryan & Deci, 2000, 2020) have received little empirical attention to this day. Thus, the present study aimed to investigate the role of school climate in predicting changes in self-determined academic motivation and grades in a longitudinal study with secondary school students. Participants are 957 Belgian students (girls = 52.87 %; M_age = 14.41 years, SD_age = 1.66 years) who took part in a three-wave, year-long study. Results from structural equation modeling showed that students’ positive perceptions of school climate at the beginning of the study (Time 1) were positively related to changes in self-determined academic motivation at the mid-point (Time 2), which in turn were positively associated with changes in grades by the end of the study (Time 3), over and above the effects of gender and age. These results have implications for educational psychology by suggesting that organizational aspects of the school setting can positively influence students’ academic grades through increases in the quality of their motivation over time.
