The purpose of this study was to provide basic data on the development of early childhood gender equality education programs. For this study, 15 individual studies related to the gender equality education program for young children in Korea were selected and 25 effect sizes were extracted. EXCEL and CMA programs were used for analysis, and the research results are as follows. It was confirmed that the overall effect size of the early childhood gender equality education program was a large effect size based on Cohen (1988). Looking at the effect size for each dependent variable, it was confirmed that all six dependent variables had a large effect size, and the difference according to the dependent variable was also significant. In addition, it was found that there was a significant effect size in four dependent variables: gender role stereotypes, gender role identification, gender equality consciousness, and gender role identity. Looking at the effect size according to the control variable, it was found that only the effect size according to the number of people in the experimental group had a significant difference. However, a significant large effect size was confirmed only when the number of people was 20 or less, 6 ~ 10 weeks in the period, 11 ~ 20 times in the number of times, and when the family connection included experience. Through this study, it was confirmed that the early childhood gender equality education program was very effective, suggesting that it is necessary to consider the difference between the dependent variable and the control variable in order to develop the program.
