The tragedy at Sandy Hook Elementary School, Newtown, CT (USA) has brought the conversation about how to reduce violence, make schools safer, improve school climate, and increase access to mental health services to the forefront of the national conversation. Advocating for comprehensive initiatives to address school safety, school climate, and school mental health begins with school psychologists. They are uniquely positioned to advocate for evidence-based initiatives that create safe and supportive learning environments and to ensure that students have access to the supports they need to be successful both inside and outside of the classroom. School psychologists have unique training in collecting and analyzing data to help ensure that school-wide systems are addressing the needs of the school and that the appropriate prevention and intervention services are available for those students who need them. They can: (1) identify key stakeholders; (2) advocate for comprehensive initiatives to address school safety, school climate, and school mental health; (3) advocate for representation on school and district level leadership teams tasked with addressing school climate, safety, and mental health; and (4) develop key messages related to comprehensive school safety and mental health that can be communicated with stakeholders. NASP has posted resources that are available to assist the school psychologist at http://www.nasponline.org/resources/crisis_safety/school-safety-resources.
