Each provincial-level unit was assigned a quota of students to be admitted to key universities, the second quota of students for regular universities within that administrative division, and a third quota of students from other provinces, autonomous regions, and special municipalities who would be admitted to institutions operated at the provincial level. Provincial-level administrative units selected students with outstanding records to take the examinations. Additionally, preselection examinations were organized by the provinces, autonomous regions, and special municipalities for potential students (from three to five times the number of places allotted). These candidates were actively encouraged to take the examination to ensure that a sufficient number of good applicants would be available. Cadres with at least two years of work experience were recruited for selected departments in a small number of universities on an experimental basis. Preferential admission treatment (in spite of lower test scores) was given to minority candidates, students from disadvantaged areas, and those who agreed in advance to work in less developed regions after graduation.
