Second, are the components of the emotional intelligence competency model for children and adolescents valid. The Delphi survey technique was used to address the research question of this study, and the Delphi survey expert panel was 10 counseling professors with at least 10 years of experience working with children and adolescents. This expert panel reviewed the draft Delphi questionnaire created based on literature review, in-depth interviews with counseling experts and counseling practitioners, open-ended surveys, and expert advice. The mean, standard deviation, and mode of the Delphi survey were calculated using SPSS 26.0, and the content validity of this model was calculated on Lawshe's (1975) internal validity calculation formula. In addition, the Wilcoxon signed-rank test was used to confirm whether the Semi-Interquartile Range (SIR) range of the second and third feedback reflecting the expert's survey results was significantly reduced after the first survey. Based on these statistical data, the final model was reviewed and selected through consultation with a three-person expert research team. As a result of the study, the final emotional intelligence competency model for children and adolescents was derived with 3 competencies, 12 competency groups, 36 competency elements, and 72 competency indicators. The implications for the counseling field in Korea were presented through in-depth discussion based on the results of this study.
