The data analysis technique used structural equation modeling with the linear structural relationship type. The study revealed that the teacher's professional attitude has an effect on teacher welfare but not on self-development, job satisfaction, or teacher performance. Teacher welfare has an effect on independent development but has no effect on teacher performance. Hence, independent development does not affect job satisfaction but affects teacher performance. Furthermore, job satisfaction has no effect on teacher performance. These findings can be used as study material for future researchers to analyze the research variables or other variables, such as leadership style, work motivation, work discipline, and others.
