The present study aimed to determine the impact of the school ethical climate on academic engagement, emphasizing the mediating role of achievement emotions in students. This research was applied in terms of purpose and descriptive-correlational in terms of method. The statistical population included all female 11th and 12th-grade students in Zahedan during the 1404-1403 academic year, totaling 29,588 students. Based on the Krejcie-Morgan table, a sample size of 379 students (198 from 11th grade and 181 from 12th grade) was selected. The research tools included the Victor and Cullen Ethical Climate Questionnaire (1988), the Achievement Emotions Questionnaire by Pekrun et al. (2005), and the Academic Engagement Questionnaire by Reeve and Tseng (2011). The validity of the questionnaires was established through content validity, and their reliability was assessed using Cronbach's alpha coefficients: 0.88 for the ethical climate questionnaire, 0.86 for the achievement emotions questionnaire, and 0.80 for the academic engagement questionnaire. Data analysis involved Pearson correlation coefficient and path analysis tests. The findings indicated that the school ethical climate had a direct positive effect on academic engagement and positive achievement emotions and a direct negative effect on negative achievement emotions. Additionally, positive achievement emotions had a direct positive effect on students' academic engagement, while negative achievement emotions had a direct negative effect. The results also highlighted that achievement emotions play a mediating and indirect role in the influence of the school ethical climate on students' academic engagement.
