This study attempted to compare co-educational and single-sex Korean high schools in terms
of their facilities for each gender and organization of teachers for decision-making processes.
The subjects of this study were 43 high schools in Seoul, Daegu, Kyonggi, Chonbuck, and
Cheju areas. Data were collected by the questionnaire which includes questions on gender
distribution of teachers for decision making processes, educational golas, school facilities for
each gender, and others. The percentage of male teachers involving decision-making processes
was higher than that of females teachers in both co-educational high schools and single-sex
high schools. Further, this study revealed that girls were lacking for school facilities such as
playground, toilets. This study suggested that teachers, educators, policy makers should aware
of these facts in order to achieve gender equity and equality in high schools.
