Critics of tracking argue that is stigmatizes students who are consigned to low track classes. For example, students can get labeled as low track or the dummy group. Critics also say that low track classrooms often have less experienced teachers, fewer resources and lower expectations. Further, critics stress that tracking is used to segregate students according to ethnicity and socioeconomic status because higher have tracks fewer students from ethnic minority and impoverish backgrounds. in this way tracking can actually replay segregation within schools. the detractors also argue that average and above average students do get substantial benefits from being grouped together.
