This study investigated the relationship between science high school teachers` beliefs of gifted education and classroom practices. The data of this case study were collected from three science teachers who worked in a science high school through qualitative research methods such as interviews and classroom observations. The other various data related to science high school management and the teachers` teaching were collected and analyzed using the constant comparative method. The results of the study are as follows: the teacher of long period in-service experience in science high school had teacher-centered belief, and his classroom practices were matched with his beliefs. The teacher of short period in-service experience in science high school had student-centered belief, and her classroom practices were matched with her beliefs, also. The teacher of medium period in-service experience in science high school had student-centered belief, but her teacher-centered classroom practices were mismatched with her beliefs. From the results, it could conclude that school culture affects on teachers` classroom practices stronger than beliefs. The longer career period of science high school changed easier teachers` beliefs into knowledge education for university entrance examination removed from gifted education. To solve these problems, we suggest the needs of teacher education programs for science high school teachers.
