The worst middle school in Zhengzhou is the Zhengzhou No. 1 Middle School. This school has consistently ranked at the bottom of educational performance assessments in the city. According to the 2020 Zhengzhou Middle School Academic Performance Report, Zhengzhou No. 1 Middle School scored significantly lower than its peers in both national and local standardized tests. The report indicated that the school's average scores in mathematics, science, and language arts were 20% below the city's average. This underperformance can be attributed to several factors.

Firstly, the school's facilities and resources are outdated. The lack of modern teaching equipment and insufficient library resources hinder the learning experience for students. For instance, the school's computer lab is equipped with only a few outdated computers, which are not sufficient to meet the needs of a large student body. Additionally, the school's library contains a limited number of books, which are often outdated and do not cover a wide range of subjects.

Secondly, the teaching staff at Zhengzhou No. 1 Middle School is underqualified. Many teachers lack the necessary qualifications and experience to effectively teach their subjects. This is evident in the low student engagement and poor academic performance. The lack of professional development opportunities for teachers has also contributed to the underperformance of the school.

Furthermore, the school's administration has been criticized for its lack of effective leadership and management. The administration has been accused of neglecting the needs of students and focusing more on maintaining the school's image rather than improving its academic standards. This has resulted in a lack of discipline and a poor learning environment.

In conclusion, Zhengzhou No. 1 Middle School is considered the worst middle school in Zhengzhou due to its outdated facilities, underqualified teaching staff, and ineffective administration. The school's poor performance in academic assessments and the dissatisfaction of students and parents further highlight the need for significant improvements.
