Based on a quantitative study of 756 children aged 12 to 18, this paper proposes a Compassion Scale for children. Following explanatory and confirmatory factor analysis, the final instrument consisted of 20 items grouped into three dimensions. Its three-factor structure explained 51.84% of the observed variance in the subjects' compassion. The internal consistency coefficient of the Compassion Scale was .89 and the split-half reliability coefficient was .75. As a result of the analysis, it was determined that Compassion Scale is a valid and reliable measurement tool that will be able to use to determine the level of compassion of children between the ages of 12 and 18-year-olds.
