Results: Psychological stress was significantly negatively correlated with academic engagement and everyday academic resilience (p<0.01). Everyday academic resilience was significantly positively correlated with academic engagement (p<0.01). Everyday academic resilience plays a partial mediating role between psychological stress and academic engagement, and the ratio of mediating effect to total effect was 75.89%.Conclusion: There is a close relationship among academic engagement, psychological stress, and everyday academic resilience among high school students.
