Purpose: The purpose of this research was to determine the effects of a safety management program on safety accident-related knowledge, attitude and behavior of elementary school students in Korea. Methods: This study adopted nonequivalent control group pretest-posttest design. The number of subjects was 34 in the experimental group and 31 in the control group. The safety management program was performed for approximately 50 minutes each session, once a week for 8 weeks. Data were collected from March 14th to June 23th, 2006, and analyzed by ${chi}^2$ test and independent t-test with SPSS WIN 16.0. Results: There were statistically significant differences in safety-related knowledge (t=3.010, p=.006) and behavior (t=18.833, p=.001) between the experimental group and the control group. The score of attitude was different between the experimental group and the control group but the difference was not statistically significant. Conclusion: The safety management program used in this study was appropriate for elemental school students and affected safety-related knowledge and behavior of elementary school students. Therefore safety education should be provided systematically for elementary schools over the whole country.
