(1) Background: The aim of this systematic review was to identify key factors for inclusion in continuing education for Korean school nurses to improve their competence in managing students with type 1 diabetes mellitus (T1DM). (2) Methods: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. (3) Results: Twelve studies were included in this systematic literature review. The factors identified for inclusion in continuing education on Type 1 diabetes mellitus included 6 competencies. These were strengthening competence in managing students with Type 1 diabetes mellitus, facilitating networking with experts and peers, the perspective of the school nurse as a leader, use of a type 1 diabetes mellitus-specific evidence-based standardized approach of care, supporting self-management to promote healthy learners, and communication and collaboration between key stakeholders. Identified barriers to accessing continuing education on type 1 diabetes mellitus were work demands, difficulty taking time off during the school year, and limited support from administrators. (4) Conclusions: Based on the findings of this study, online or e-learning continuing education on type 1 diabetes mellitus must be developed for school nurses who manage students with this condition.
