The phenomenon of paid substitute classes frequently occurs in colleges and universities, and the key to governance lies in the school as a manager. Generally speaking, senior students will arrange special time for internships and job hunting, and the curriculum of each institution and major is different. Some schools generally do not arrange courses or reduce courses, which is relatively flexible. Some schools are already in the third year of high school, but the courses are still full.

Except those students who skip classes and seek excitement, what remains is more reflection on teachers' teaching work. Schools should think about teaching reform, not only to promote curriculum reform, but also to continuously strengthen the construction of teachers. More is for the sake of students, according to different needs and different grades of students' learning status, flexible learning methods are introduced.

Teachers should innovate teaching contents and methods to stimulate students' interest in learning to the maximum extent. Thereby reducing the occurrence of truancy and substitute classes.

Substitution refers to the behavior that college students spend money to find someone to substitute for classes, which is called "substitution". It is not uncommon for college students to skip classes, but they pay students to substitute classes and form a strong substitute network.

These substitute families help students to take classes, hand in the teacher's roll call, and charge each class 18 yuan (usually) to 15 yuan (holidays). Some students even set up a lot of QQ substitute groups, openly posting in the forum to ask people to substitute or provide substitute services. They also have a more professional name: "Attendance Agency".
