The new college entrance examination reform in our province will be implemented from the fall semester of 2022. In order to adapt to the new college entrance examination reform, implement the rigid requirements of the reform policy of selecting courses and moving classes, and ensure the sustained and high-quality development of high school education, after fully studying the existing high school track system and school-running conditions in our city, we decided to rationally adjust the high school track system, re-optimize the layout, and integrate the teaching staff. Therefore, No.3 Middle School and No.4 Middle School were merged and the teachers were optimized.
