Hi Marina, I loved how much this article focused on the scientific backing behind the importance of social and emotional skills. From a human behavior perspective, it is critical to begin to practice these skills early and I would argue as early as a few months old. With the change in the HPA axis of children exposed to constant stress, pre-school and elementary schools must be prepared to help students learn to self-regulate and build practical intelligence skills. I have read of a curriculum called PATHS, which is implemented across pre-k and elementary grades and focuses on many of the practical intelligence skills you referenced. The curriculum focuses on teaching the students social and emotional competencies as well as reducing aggressive behaviors. While it is not a fully comprehensive program involving parents, classrooms, and communities as you suggested, I think it is a great start to incorporate important skills to make a change on child abuse, neglect, and mental health disorders.
