Infants and toddlers with developmental disabilities or delays use early intervention (EI) for rehabilitation services. Yet, EI quality is compromised for racially and ethnically diverse and socially disadvantaged families. A key lever to improve EI quality is family-centered care, an evidence-based approach that is grounded in family engagement for shared decision-making. This project is motivated by the need to give families a smart and connected option for engaging in the design of the EI service plan for their child.
