Studies on children s first interactions with their environment point to possible effects of toxic stress in childhood, as a facilitator of risky behavior in adolescence, in addition to impairments for the development of cognitive and socioemotional skills (Van der Kolk, 2003). Due to the need for schools to be prepared to serve children who experience high and frequent stress rates early in their lives and need to deal with its effects, the school as a whole needs to be a space of safety and resilience so that children can experience a learning process. From an ecological perspective of developmental psychology, the objective of the present study was to carry out an integrative literature review to identify practices and models of trauma informed education, aimed at protecting against the effects of toxic stress on cognitive development in preschool and early years of elementary school. Fifty articles were selected on different models of trauma informed education in the first years of schooling and with approaches aimed at the school as a whole. From the analysis of these articles, nine main aspects were identified among the different models presented: self-regulation, professional training of trauma and toxic stress, community engagement, psychologically safe environments, emotional support for teachers, routines and rituals in pedagogical practice, secure attachment, individual or group therapy and regular contact with families. It is believed that these elements can guide interventions aimed at early childhood, in the context of education.
