In recent years, different types of programs to improve emotional skills have been implemented in educational contexts, mainly in schools. However, few studies have been carried out in non-formal educational contexts, and also include an assessment of program effectiveness. The aim of this research was to evaluate the effectiveness of a skill development program in emotion perception and understanding emotions for children, applied during a summer school. The study used a randomized experimental design with repeated measures, pretest-posttest assessments, and a control group. The sample was made up of 22 participants. The intervention consisted of a training program, based on the skill model. To check skill acquisition, an adaptation of the ACES test was applied. The results reflected a significant increase in emotion perception and understanding emotions in the experimental group. This study contributes positive data on the effectiveness of the program and could be applied in different contexts.
