Developing creativity in socio-educational organizations facilitates progress towards sustainability, benefiting its professionals and users. The objective of this work is to analyze the creative climate in organizations that intervene with vulnerable groups to promote sustainability through Quality Education (SDG 4), Gender Equality (SDG 5), and Reduced Inequalities (SDG 10). A descriptive–correlational study was conducted with 203 professionals from associations, foundations, and social services councils. The CPPC-17 scale was applied, and the data were analyzed using descriptive statistics, nonparametric tests, and cluster analysis. The results showed that the professionals presented high levels of creative potential. The opportunity to participate in work groups and the freedom to perform tasks favored creativity in the organizations. The main obstacles to creativity were the lack of incentive to take risks and of rewards for creative ideas. The profile of professionals with high levels of creative climate was mainly composed of association workers and those trained in Education, Psychology, and Speech Therapy. Significant differences were obtained in variables related to the organization (e.g., typology) and in personal variables, such as the academic background of the trainers. These findings should be considered to improve the creative climate in these organizations with a view to providing quality, egalitarian, and equitable education.
