Only 10% of eligible infants and toddlers with developmental delays nationwide receive early intervention services, and CA serves fewer children than the national average. This is due to challenges such as spotty screening, tenuous linkages to referral and evaluation, and crossing multiple agencies. Massachusetts has a unified early childhood data system and robust interagency linkages, resulting in a greater percentage of their infant and toddler population served. Implementing a unified data system and interagency streamlining in CA could increase the number of children and families served.
