balanced development
Article 22 of Chapter III of the Compulsory Education Law stipulates that people's governments at or above the county level and their education administrative departments should actively promote the balanced development of schools and narrow the gap between schools. This regulation aims to ensure that all students can receive education under equal conditions and avoid unfairness caused by uneven school resources.
lawbreaking
The school separates key classes from non-key classes, which obviously violates Article 22 of Chapter III of the Compulsory Education Law. Therefore, schools should strictly abide by the compulsory education law and provide students with a fair and just learning environment.
