While school nurses are accountable for their own practice, stipulations in individual employee contracts may require supervision and evaluation. Like teachers and others who provide services for students, school nurses can benefit from self-assessment, peer review, and supervision and performance evaluations that focus on fostering continuous development of practice competencies and professional growth. Appropriate clinical supervision and evaluation of school nurses is essential for delivery of high quality and safe care in school communities everywhere. Developing and strengthening school nursing clinical competencies such as responding to students' healthcare needs and implementing evidence-based protocols and best practices positively impact student health and academic success.
