In response to executive order mandates from states and governors, many early care and education (ECE) settings closed or transitioned to providing virtual services to children and families during the COVID-19 pandemic. For ECE coaches, these closures resulted in the need for rapid adjustments in the way they provided coaching services. These adjustments occurred with little time to prepare and minimal knowledge of how best to understand ECE program needs, structure coaching sessions, develop and implement coaching content, or assess the progress of teachers and providers in a virtual context. This two-part series of briefs gives an overview of the process and lessons learned during the transition from in-person to virtual coaching for the Detroit Early Learning Coaching Initiative (DELCI). This brief, the first in the series, presents an overview of DELCI, including a summary of the coaching model, the process of adapting it to a virtual format during COVID-19, and initial experiences with virtual coaching implementation. The second brief in the series will describe how virtual coaching was implemented over time, including lessons learned. [For the second brief, "Lessons Learned from Virtual Early Care and Education Coaching during COVID-19," see ED613903.]
