Subjective happiness has been found to be associated with key psychological outcomes. However, there is paucity of research that assessed how subjective happiness is related to a number of positive student outcomes in the educational setting. The objective of the study was to assess the associations of subjective happiness with academic engagement, flourishing, and school resilience among 606 Filipino high school students (mage = 13.87; nboys = 300, ngirls = 305, nmissing = 1) in the Philippine context. Results of path analysis demonstrated that subjective happiness positively predicted behavioral engagement (β = .08, p < .01), emotional engagement (β = .08, p < .01), flourishing (β = .17, p < .01), and school resilience (β = .18, p < .01) even after controlling for gender. The theoretical and practical implications of the findings are discussed.
