The purpose of this study was to investigate the structural relationship among creative learning efficacy, self-regulated learning ability, and subjective happiness of aeronautics major students. A total of 300 college students(freshmen through senior) of H University in Chungchung, Korea participated in this study. Correlations and test of structural model fit were performed by using SPSS 23.0 and AMOS 22.0. The results of this study were as follows. First, the results of the comparison across the grade level showed that there were increasing tendencies of scores of creative learning efficacy, self-regulated learning ability, and subjective happiness measures. Second, the results of Pearson correlation analysis showed that there were statistically significant correlations among creative learning efficacy, self-regulated learning ability, and subjective happiness of aeronautics major students. Third, the result of the path and model fit tests showed that all the model fit indices of γ² , TLI, CFI, RMSEA were met the acceptable criteria, and shown to be a suitable model structure. The significance and implications of this study were provided.
