The Birth-to-Three Equity Initiative launched in April 2015 as a multiyear systems change process to strengthen equitable access, services, and child and family outcomes in the "early intervention" system in Martin Luther King County, Washington. This article describes the training of agency leaders and "equity facilitators" that is underway to support universal access to a foundational level of training for all staff which addresses racism at individual, organizational, and systemic levels. The training also supports current staff members to strengthen their cultural competence with families they are already serving. The authors discuss how "Equity Change Teams" are being launched to support each organization's leadership and staff to analyze policies, procedures, and practices with an equity lens and to then develop and implement action plans to promote equity.
