This study considers the diverse aspects of the correlation between outcomes of the survey, “Qualities and Abilities Questionnaire” (Wakamatsu, Hiyaoka et.al. , 2017) covering qualities such as “subjectivity and activeness,” “pride,” and “cooperation in labor,” conducted among 1,775 students from 3rd grade in elementary school to 3rd year in junior high school, and their ability to adapt to school. The study also analyzed the quantitative differences seen among the qualities and abilities of the different grades. Firstly, multiple regression analysis showed that the standard partial regression coefficient β was significant for “pride” and “cooperation in labor,” showing slight positive influence to adaptability to school. Secondly, the analysis of variance on grade (7) x subscale (3) showed that the quantitative difference in qualities and abilities depending on the advancement of grades are different among “subjectivity and activeness,” “pride,” and “cooperation in labor.” Nurturing these qualities and abilities will result in improving the skills that will become the foundation for the students’life-long social life, and there is need for further consideration of changes that occur according to advancement of grades.
