What Is Zero To Three and What Does the Organization Do?

Updated

Zero To Three (zerotothree.org) is an early childhood development organization focused on ensuring a strong start for every child. Its stated premise is that "the first three years of life are the most important for lifelong mental health and well-being." The organization supports three audiences — families, professionals, and policymakers — through resources, training, research, and advocacy. If you are a parent or caregiver looking for developmental guidance, a professional seeking training, or someone tracking early childhood policy, the site is organized around those three paths.

Who Zero To Three Serves

The homepage frames the work around the people who "shape the lives of young children":

  • Parents and caregivers — practical support for understanding child development, including community care resources, research-based tips, and parenting tools.
  • Professionals — early childhood resources and training for people working in early learning, health care, mental health services, family support programs, and related fields.
  • Policymakers and legislators — research and collaboration aimed at influencing legislation on early childhood education, child welfare, and child care.

Fields of Focus

Zero To Three lists the critical issues it addresses through its trainings and resources:

Focus area What it covers
Infant and Early Childhood Mental Health Social-emotional development in the earliest years
Trauma Effects of early adversity on young children
Early Learning Development and learning before age three
Early Development General developmental milestones and support
Physical Health & Nutrition Health and feeding foundations
Child Care Quality and access in early care settings
Child Welfare Systems serving infants, toddlers, and families
Economic Security Family financial stability as a developmental factor

What the Organization Actually Offers

For parents and caregivers: projects and programs plus early childhood development resources, including community care resources and research-based parenting tips and tools.

For professionals: training programs, conferences, free webinars, and resources designed to deepen understanding of childhood development and strengthen practice. The site highlights a LEARN Conference (LEARN 2026) as a way to "find your people" in the field.

For policy and advocacy: research and direct collaboration with policymakers and state legislators on legislation related to early childhood education, child welfare, and child care.

Impact and stories: the site publishes an impact report and "Impact Stories" — first-person accounts from families. One featured story, from a parent named Shania, describes the moment she worried whether she could give her son Cohen "the chance to thrive," illustrating the kind of family experience the organization centers its work on.

How to Decide If It's Useful to You

  • You're a parent or caregiver wanting plain-language developmental information and parenting tools — start with the parent and caregiver resources.
  • You work with young children and need training, webinars, or conference access — the professional resources and LEARN Conference are the relevant entry points.
  • You follow or shape early childhood policy — the policy and advocacy section covers the legislative areas the organization engages with.

The site does not display pricing for its resources or trainings on the pages reviewed here, so check individual program or conference pages for any cost or registration requirements before planning to attend.
