Abstract
The purpose of this study was to examine longitudinal changes in school morale of elementary school students in one class per grade. Participators were 31 4th grade, 29 5th grade and 28 6th grade for a total of 88 students. First, to assessing the level of psycho-educational services, the children were classified into four groups using a school life scale. Next, longitudinal changes in school morale were examined. The results showed that longitudinal changes in school morale are characteristic of different groups. There were two groups: one group showed no change in school morale, and the other group showed changes in relationship with friend and relationship with class. These results suggest that when providing psycho-educational services to children one class per grade, it is necessary to plan and implement support according to the stage of psycho-educational services. Finally, a discussion was held on the direction of support at each stage of the psycho-educational services.
