根据学生的成绩把学生分成不同等次的班级进行教学在中小学是非常普遍的。尽管教育主管部门明令禁止,但很多学校依然我行我素或不断变换花样进行应对。比如,上级取消以实验班为名进行单独招生资格,有的学校就改在录取后再进行一次选拔;明令不准办重点班,有的学校就改头换面称之 It is very common for primary and secondary schools to teach students in different classes according to their grades. Although the education authorities have banned it, many schools still go about their own way or change their designs to deal with it. For example, the superiors canceled the qualifications for individual enrollment under the name of the experimental class, and some schools changed their choices after taking the admission; they explicitly ordered no key classes, and some schools changed their names.
