The purpose of this study was to investigate teachers' suitable attitude toward high school students concerning their career guidance. The teachers' attitude that had satisfied students in the past and the attitude and character that students want their teachers have when they ask for advice were both investigated. Based on this preparatory investigation, a questionnaire was made which contained 60 items. Subjects were made of 750 high school students in general courses and commercial courses. As a result, when the career guidance was held in high schools, teachers should have shown a more loving care toward their high school students. Furthermore, teachers should have better knowledge and information and should fatherly cope with students when they were at a loss concerning their future life. Especially, such fatherly behavior is important for the students in commercial courses during their career guidance.
