There are three types of technical schools. According to relevant public information, technical colleges are divided into three categories: technical schools, senior technical schools and technician colleges. Technical schools, which belong to secondary vocational education, recruit junior high school graduates and train intermediate workers, which is equivalent to high school education. Senior technical schools and technician colleges belong to higher vocational education and can recruit junior high school and senior high school graduates, but junior high school graduates only have different academic systems. Senior technical schools train senior workers, which is equivalent to college education.
