The purpose of the study was to investigate the effects of education and training investment on
employees' job satisfaction and organizational commitment in term of longitudinal research in small and medium-sized corporations. First, second, third-year data of Human Capital Corporate Panel (HCCP) was used to analyze the relations among corporations' education and training investment per capita, organizational commitment, and job satisfaction, using latent growth modeling (LGM) technique. In the result, we developed the conceptual path diagram and in turn, compared the latent basic models with the linear curve models. Finally, the path diagram of the latent growth modeling showed the fit index was appropriate. The intercept of exogenous variable, which is education and training investment had positive effects on the endogenous variables, which is organizational commitment and job satisfaction. In turn, the education and training investment in each year had to do with the annual rate of job satisfaction and organizational commitment. We conclude that the education and training investment needs to be increased in impacting job satisfaction and organizational commitment, which affect, in final, the finance outcomes of the corporations.
