The primary purpose of this study is to examine the personality traits and job satisfaction of primary school substitute teachers across different demographic variables in Changhua County. A total of 200 questionnaires were distributed, with 158 responses collected online. The key findings of the study are as follows: The personality traits of primary school substitute teachers tend to be more agreeableness and conscientiousness. Significant differences in personality traits were observed based on background variables such as gender, age, marital status, position, and school size. Significant differences in job satisfaction were found among background variables such as age, years of teaching experience, and school size. There is a positive correlation between the personality traits of primary school substitute teachers and job satisfaction. Specifically, the ability to predict the job satisfaction of substitute teachers in elementary schools is most strongly influenced by agreeableness, extroversion, openness to experience, and conscientiousness. This suggests that schools might enhance job satisfaction by considering these traits in their hiring. By contrast, schools might enhance retention and improve support strategies particularly by considering teachers with a trait of neuroticism. Future research may be conducted to compare the differences between substitute and regular teachers.
