Learn about Best Starts strategies, approach, and history

The earliest years of a child’s life offer a unique window of opportunity to support lifelong health and well-being. As infants and children learn about the world around them and the people in their lives, feeling loved, supported, and safe is crucial for their growth and development. Best Starts prenatal to five investments reach children and families where they are in their prenatal to five years—homes, child care settings, and communities—to support healthy child development and family well-being.


Programs and strategies include:

Home-based services: Best Starts supports a range of home-based services to meet the needs and build on the strengths of many different children, families, and communities.

Community-based parenting supports: Best Starts seeks to strengthen organizations in communities that serve expecting parents, families, and caregivers. Funding will support services such as prenatal and breastfeeding support and parenting education.

Child care health consultation: Best Starts will support the design of a county-wide system where multi-disciplinary teams of experts provide voluntary coaching and support to child care providers and caregivers on disease prevention, safety, trauma-informed care, and other needs communities identify.

Promoting healthy development: Best Starts seeks to ensure that parents can easily access developmental screenings to understand their child’s unique development and link them to services if they need additional support. Best starts also supports building a comprehensive infant mental health system to encourage healthy attachment between caregivers and children.

Building the skills of adults who work with children: Best Starts will support teachers, health care providers, and others who serve children and families to have the latest knowledge on child development, brain science, and trauma-informed care.

Supporting innovation: Best Starts will support efforts that do not fit in any of the other funding buckets but still creatively serve communities through new practices, adaptations, peer learning and capacity building, systems improvements, and any other means of achieving Best Starts goals.

Linking systems: Best Starts will build a network of information hubs and community-based navigators to
ensure families are fully informed about the resources available to them and can easily access them in the language they prefer, with providers who understand or reflect their cultural background. This coordinated network, called Help Me Grow, will integrate all other Best Starts supported services and systems.


These strategies focus on supporting positive development for children and young people as they progress to adulthood. Best Starts embraces a strengths-based approach, recognizing that we must sustain the gain that is made by investing early while also responding to the realities of adversity and trauma across communities. Our focus is on promoting and building resilience and protective factors, and preventing or intervening early to assure that King County youth have the supports they need to thrive.


Programs and strategies include:

Partnerships with schools: Partnering with schools and their partners to create environments that support young people in school such as:

  • Trauma-informed and restorative practices in the school environment
  • School-based health centers
  • School-based mental health screening and support
  • Quality out of school time

Building a pipeline to success: Eliminating the ‘school to prison pipeline’ and building a ‘school to life success pipeline.'

Parent and community connections: Ensuring that communities are safe and connected so that children, youth and young adults live, learn, work, play in environments with access to healthy and affordable food, opportunities for physical activity, and can actively engage in environments that are safe and hazard free.

Youth development:​ Providing young people with the opportunities and tools they need to weather challenges during adolescence and be ready to flourish as adults, including

  • Mentoring
  • Healthy and safe relationships and domestic violence prevention
  • Positive identity development
  • Youth leadership and engagement opportunities

Transitions to adulthood: ​Helping youth and young adults who have had challenges successfully transition to adulthood through employment and education support.

Youth and family homelessness prevention:  Helping youth and families that are on the verge of being homeless by addressing their specific needs, such as clothes for a job interview or help with the first month’s rent. The individualized approach in this initiative is based on a highly successful pilot project funded by the Bill and Melinda Gates Foundation.

Ten percent of Best Starts for Kids funding sustains and expands the partnership between King County and The Seattle Foundation on Communities of Opportunity, which is based on the latest research regarding the impact of place on a child's success. It also supports local communities in building their own capacity to create positive change.


COO strategies were developed in partnership with community leaders and organizations and focus on quality affordable housing, health, community voice and connection, and economic prosperity. COO’s place-based focus recognizes that certain communities experience greater disproportionality than others. Implementation is designed to be responsive to emerging needs, adapting to community-centered innovations and leverage other investments.

The vision that became Best Starts for Kids began in 2014 under the leadership of Executive Constantine. King County staff began examining how the County could improve outcomes and support individuals and communities to achieve their full potential.

The Best Starts for Kids Levy (Ordinance 18088) was approved by King County voters in November 2015. Over the next several months, more than 1,000 community members provided input at community conversations, focus groups and interviews across King County. An additional 1,000 youth surveyed for the Youth Action Plan provided feedback. Collectively, this community engagement shaped Best Starts for Kids’ guiding values, focus, and approach to change.

Best Starts for Kid costs the average King County property owner about $1 per week.

King County is the most populous county in Washington State and the 13th most populous county in the U.S. King County’s 2.1 million residents reside in urban, suburban, and rural communities.
