School psychologists are one of the most knowledgeable professionals in the school setting about the prevention and intervention of mental health disorders.  Choose a behavioral or mental health issue that is of interest to you that impacts children and adolescents (it can be a DSM-5 disorder, such as ADHD or a broad issue such as bullying).  Describe how you would implement a prevention and intervention system in a school setting to target this concern.  Make sure you identify some elements of a tiered system approach that you would utilize for your population, including universal, secondary and tertiary components.
