Mental health disorders in school-aged children are on the rise. The need for mental health care is well recognized, and the provision of this care in schools is recommended. An integrative review explored how school nurses view their role in addressing students' mental health. Fourteen articles were identified, eleven using a qualitative design and three using a quantitative design. Findings suggest that school nurses see their role as trusted members of the school community. They perceive upholding standards of practice as an integral part of their position and recognize competence in mental health care to be highly important. Practice recommendations include providing school nurses with evidence-based training on managing the mental health needs of students, as well as ensuring access to school nurses who can provide mental health supervision in the community.
