Pingliang Electromechanical Engineering School is a full-time general secondary specialized school. Its graduates can take the college entrance examination for students from three colleges and universities, or they can take the general college entrance examination, but they can only choose one of them and cannot take the other. Both of them can apply for universities in other provinces.

The students in the three schools are students from technical schools, technical secondary schools (secondary specialized schools) or vocational high schools (vocational high schools/senior vocational high schools). Its orientation is to cultivate a large number of skilled talents and high-quality workers on the basis of compulsory education, and to carry out vocational knowledge and vocational skills education according to the requirements of professional posts while educating high school students.

The unified national examination for enrollment of ordinary colleges and universities stipulates that all candidates who apply for "three-school students" in higher vocational colleges must be fresh graduates of qualified schools approved by the Provincial Department of Education. Graduates from the "Three Schools" can choose to take the unified entrance examination for higher vocational colleges (commonly known as the "Three Schools" college entrance examination) or the general college entrance examination held in June, and they can only choose one and cannot repeat it.
