Early Childhood 101 (EC 101)
Building shared understanding of the early childhood system to support informed decisions and coordinated action
Why This Matters
Early childhood systems are complex, spanning multiple program types, funding streams, and policies. Key stakeholders, including funders, legislators, policymakers, and community and state leaders, need a shared understanding of how the system works in order to make informed decisions and take coordinated action. EC 101 helps to build that common language and shared understanding.
How We Drove Change
Using a Journey Map, EC 101 illustrates the experiences of the nearly 360,000 young children in Massachusetts, emphasizing how social determinants, including socioeconomic status, race, education, and geography, influence a child’s development and access to supports from health care to early learning.
EC 101 focuses on
four interconnected systems:
- Health & Wellbeing
Supporting children’s physical, mental, and developmental health - Family & Caregiver Support
Ensuring families have access to guidance, resources, and social supports - Education & Care
Providing high-quality early learning opportunities across settings and program types - Community Engagement
Connecting families, providers, and communities to build coordinated support networks

Our research began with the question:
"A child is born in in Massachusetts, then what happens?
Through deep investigation into existing research, conversations with experts, and analysis of data regarding the early childhood experience, we developed the following systems-level buckets to explain children and families’ experiences in the Commonwealth.
Timeline and Scale
EC 101 launched in January 2023. It is periodically updated to reflect high-level changes in data, policy, and the early childhood system.
