Does the subject want to ask "how many echelons are there in Fengzhen Primary School"? The third echelon. According to the news from Shanghai Hongkou District Education Bureau, Fengzhen No.1 Primary School belongs to the third echelon. Evaluation criteria of the third echelon schools: new schools with great potential or ordinary primary schools with obvious progress after the turnaround (and some original key primary schools with slight retrogression) have the potential to become excellent schools in the future, but there is still room for improvement in both performance and students.
