随着九年制义务教育的实施，小学毕业生将全部进入初中就读。由于生源及各校教学质量的差异导致初中阶段学生入学前成绩上的参差不齐。一些学校为追求升学率而对这些学生实行分班，并集中将新入学的初中学生按小学毕业统考成绩从高分到低分分班，并集中学校的骨干教师授高分班? With the implementation of nine-year compulsory education, primary school graduates will all enter junior high school. Due to the differences in the quality of students and the quality of teaching in each school, students’ grades before the middle school stage were uneven. Some schools have divided these students into classes in pursuit of higher school enrollment rates, and have focused on graduating the newly enrolled junior high school students from high to low scores in the elementary school graduating entrance examinations, and centralized the school’s key teachers to give higher grades.
