“…The human resources that have an impact on students' performance include the number of teachers and management personnel at the school level (student-teacher ratio, part-time or full-time teacher), the quality (education background [8][9][10], title), the structure (gender [11,12], nation identity [13], teaching age [14], regular staff or not [15], age [16], and the major, subject). At the student level, students' gender [17,18], nation identity [19][20][21], only child or not [22] and learning factors such as self-education expectation [23], learning attitude, extracurricular reading and extracurricular learning [24], parents' educational background [25], educational expectations for their children [26], economic status [25] and peer influence [27] will also affect students' performance. Considering the research purposes of this paper and that primary and secondary school administrators almost also undertake daily teaching but that there is a large difference in the number of teachers between Han and ethnic minorities, family resources and peer influence are included in this study as control variables, the impact of managers' and teachers' students' nationalities structure on students' performance is not considered separately.…”
