Professional rank is an important indicator of the professional capacity of compulsory education teachers. A rational professional rank evaluation system plays an important role in mobilizing the enthusiasm of teachers, improving the overall quality of teachers, and promoting the development of education. Based on stratified random sample data from compulsory education teachers in 23 counties and cities in 12 Chinese provinces, this study analyzes the multiple impacts of urban and rural compulsory education teacher professional rank on teacher salaries, development opportunities, and work duties. The authors found the following: (a) Urban-rural differences exist in the opportunity to access compulsory education teacher professional rank; rural school teachers are disadvantaged in accessing professional rank, especially senior rank; (b) Significant salary differences exist among teachers of different ranks, as well as significant urban-rural differences in the total monthly incomes and monthly salary among teachers of the same rank; (c) Teachers of different ranks have different opportunities to participate in training and undertake school duties. Within the same rank, rural teachers have fewer opportunities to participate in high-level training and have a higher proportion of school duties; (d) Significant differences exist among teachers of different ranks in terms of average classroom hours per week and important duties undertaken. There is a significant urban-rural difference in average weekly classroom hours and important duties among teachers of the same rank; weekly classroom hours are higher for rural teachers, while they have more opportunities to undertake important duties.
