Background: The COVID-19 pandemic disrupted routine school operations, including school health programs. This study aims to describe the pandemic's impact on school health service delivery from the perspective of Maryland school health partners. Methods: We conducted semi-structured interviews with health service representatives from public schools (K-12) between July and December 2021. Interviews were recorded, transcribed, and coded through an iterative process to develop analytic themes. Results: Twenty school health partners from 15 Maryland school districts participated. Participants identified key impacts of COVID-19 on school health: (1) COVID-19 disrupted delivery of services such as dental, mental health, and preventative care, (2) COVID-19 necessitated changes in service delivery platforms, (3) COVID-19 affected school health staff through increased responsibilities and staffing shortages, and (4) COVID-19 prompted schools to become hubs for community outreach and health education. Implications for School Health Policy, Practice, and Equity: Consideration of school health service disruptions and the increased demands on service providers may inform future priorities for school administrators, health departments, and policymakers. Conclusions: COVID-19 impacted the timing and method of service delivery as well as the roles of school health staff and schools themselves in public health and education.
