The effects of an educational support program on school children who participated in the programs held in 2013 were examined in this study. The educational support program was held at a clinic of school psychology at the Center for School Education and Research of Hiroshima University called Niko Niko Room. Twenty-nine school children and their guardians answered questionnaires about the program. Results showed that the children and their guardians both highly evaluated the ability of the teachers (university students) who supported the children, and were satisfied with the program. Communication between teachers (university students) and children, and between teachers (university students) and guardians seem to play an important role in the children’s interests of arithmetic and in the satisfaction of the programs.
