1) Purpose and method : The present report aims to trace the change of pupils' attitudes toward teachers during a school year, and then to examine the relation betweeh pupils' attitudes toward teachers and their attitudes toward school. To find out the change of pupils' attitudes during a year, investigation was made, five times each time using the same scale ; the first one was a week after the biginning of a new school year, the second a month after, the third at the end of the first term, the fourth at the end of the second term and the fifth was at the end of the school year. The scale of attitudes was made after the Thurstone method of equal-appearing intervals. subjects were the fourth-year pupils of four classes in a certain primary school. 2) Results of investigation : In attitudes of pupils toward teachers there was a difference among the four classes which is statistically significant. The difference came in the personality or character of the teachers and in the educational guidance attitudes among the teachers. Throughout a year of investigation five times repeated, the pupils of three classes of the four retained an almost constant attitude toward their teachers, without a statistically significant difference of attitudes ; on the other hand the pupils of the fourth class changed in their attitudes with a statistically significant difference of attitudes at each time of investigation. In personality or character and educational attitudes of guidance, the teachers of the former three classes were average, while the teacher of the latter class was somewhat old deviate. The relation between pupils' attitudes toward teachers and their attitudes toward school was one of a close correlation, as denoted by a coefficient of correlation which is statistically significant. Thus it was found that the more pupils formed an intimate attachment for their teachers the more they came to like school.
