It is the position of the National Association of School Nurses (NASN) that student behavioral health and wellness must be prioritized for students to successfully access and engage in educational opportunities. It is imperative that school systems respond to, and address, student behavioral health and wellness to ameliorate disparities related to the social determinants of health. School nurses are often the initial access point to identify concerns, determine interventions, and link families to school and/or community resources. This document provides the background and rationale for NASN's position on the behavioral health and wellness of students.
