This study draws the following hypotheses. Firstly, education has a positive effect on the slope of the learning curve and a negative effect on its intercept. Secondly, corporate training has a negative and positive effect on the slope and intercept of the learning curve, respectively. The regression models are based on an ordered logit model. The dependent variable of this model is skill level, and its main independent variables include tenure with the first and second orders, education levels, training hours, interaction of tenure and education, and interaction of tenure and training hours. This study finds that the estimates for tenure with the first and second orders are significantly positive and negative, respectively, indicating that the learning curve is invertedly U-shaped with its peak on 24 years of tenure (53 years in terms of age). The results of this study indicate that junior college and university or higher education raise the slope of the learning curve significantly, while technical high school does not affect its slope significantly. On the other hand, the intercept of the learning curve is negatively affected significantly by technical high school, junior college, and university or higher education. The results also indicate that corporate training raises the intercept of the learning curve, and weakly drops the slope of the learning curve
