The questionnaire survey, which consisted of questions regarding personal background, volunteering experience, training, interpersonal relation, and satisfaction, was administered for two weeks in November 2011 to volunteers in 34 elementary schools in Anyang and Gwacheon area. Data collected from 524 volunteers (response rate was 60.6%) were analyzed by descriptive statistics, t-test, ANOVA, and correlation analysis. Most of the volunteers were female, 36-40 in age, and with college education. The biggest group had seven to 12 months volunteering experience, less than six hours, and frequencies for the last six months. Seventy-four percent had training before the volunteer service and 50.9% had continuing education experience. The mean score of satisfaction was 3.64 on a five-point Likert scale.
