The effects of Niko Niko Room’s educational support programs of 2013 on university students were examined in this study. In this program, university students supported school children with their studies, especially arithmetic, based on cognitive counseling (Ichikawa, 1993). The actual study support was taught and supervised by supervisors, and cases were taken under review by the group. Data of 55 students who answered questionnaires before and after the programs were analyzed. Of the 55 students, 23 students did the actual study support and 32 students observed the study support done by other students. Results showed that students’ abilities of “teaching skills”, “relationship between students and guardians”, and “assessment” were formed in both the students who did the actual support and who did the observations through their participation in the programs. Results also showed that students’ ability of “lesson induction” was formed through the actual support.
