Each year, more and more students are entering the school system having experienced different forms of trauma, such as violence, death, abuse, and illness. Children who are exposed to trauma run the risk of facing negative long-term effects that include mental illness, depression, and anxiety. This literature review provides an overview of how exposure to trauma affects children's mental health, as well as student learning and behaviour. Academic performance, school attendance, and overall intelligence are affected by exposure to trauma. Suggestions for supporting students with trauma exposure range from everyday interactions to intensive intervention programs, which include traditional and non-traditional practices as well as group and individual programs.
