Diabetes Technology in the School Setting for Preschool-Aged Children.

Diabetes technology has transformed the management of type 1 diabetes (T1D) and improved glycemic outcomes, yet preschool-aged children with T1D remain a uniquely vulnerable population. Complete dependence on caregivers and practical considerations such as limited body surface area and skin sensitivity create distinct barriers to effective technology use. These challenges are often compounded by the transition to daycare or school setting, where disruption in diabetes care coordination between home and classroom can compromise glycemic outcomes. This review synthesizes the evidence for diabetes technology use, summarizes the current guidelines, provides practical considerations, and reviews guidance for training protocols and competency requirements in the educational setting. School-based legal protections are discussed, including Section 504 plans and Individualized Education Programs, which should outline the diabetes-related accommodations required in the school setting in alignment with the Diabetes Medical Management Plan. Targeted interventions to improve training of school/daycare staff, facilitate communication across home and school settings, and address disparities in technology access are essential to optimize care and improve long-term health outcomes.
