This is a report of a secondary analysis of data from a published quasi-experimental feasibility study of the effects of implementing diagnoses from North American Nursing Diagnosis Association International, interventions from the Nursing Interventions Classification, and outcomes from the Nursing Outcomes Classification (referred to as NNN) on nurses' power and children's health outcomes. For this study, the NNN terms that were frequently used by nurses in the original study were identified through the nurses' printed reports of health-related visits (N = 766) with 103 New York City children in the 4th and 5th grades in six schools. The findings indicate that a large majority of nurses' efforts were focused on health promotion and management of risk states. Health problems such as pain and ineffective airway clearance were identified and were treated when present. Findings from this study can be combined with findings from previous studies to identify the diagnoses, interventions, and outcomes that are relevant for school settings. Use of the relevant NNN terms will provide data to support evidenced-based school nursing practice, education of school nurses, development of policies, and communication of the value of school nursing practice to stakeholders.
