What does Jiangsu mean by canceling the unified recruitment?

All high school enrollment places will be directed to the school. The cancellation of unified recruitment in Jiangsu means that all the enrollment places of senior high schools will be directed to schools, and there will be no competition between schools, which will turn the competition for senior high school entrance examination into competition among students within schools, which is conducive to the balanced development of schools in the region, especially the development of weak schools.
