Three students are the general names of students who are receiving secondary vocational education. Their students come from secondary vocational schools (secondary specialized schools, vocational secondary schools), vocational high schools (vocational high schools, vocational technical schools, vocational schools) and technical schools (technical schools).

Secondary vocational education is influenced by high fever and people's traditional ideas. At present, secondary vocational school students spend two and a half years in school (the last half year is social practice, and some schools call it work-study alternation).

Students mainly study vocational skills, but also learn some cultural knowledge (Chinese, mathematics, foreign languages). From 20 17 to 20 18, there were 2.336 million secondary vocational school graduates (subject to the students who finally got the diploma).

Students who want to attend full-time colleges and universities mainly adopt single or unified recruitment, but it should be noted that the examination syllabus of the general college entrance examination is mainly based on the textbooks of ordinary high schools.
