It is not uncommon for children, adolescents, and families to seek counselors’ services when they are in crisis. Despite a growing literature base in school crisis prevention, intervention, and preparedness, there is a relatively scant literature base addressing mental health crisis intervention for professional counselors. This chapter addresses elements pertinent to crisis intervention, including mandated reporting, and associated trauma or grief. Children understand and process grief and trauma differently based on developmental and cognitive ability levels. Unfortunately, it is not uncommon for children to experience traumatic events before reaching adulthood. As an example, international studies document that child sexual abuse, physical abuse, or domestic violence affects approximately 25% of children. War, natural disasters, motor vehicle accidents, violence, terrorist acts, and refugee experiences can all contribute to trauma reactions. Regrettably, if left untreated, complications associated with unresolved trauma or grief can last well into adulthood.
