Santa Clara County Office of Education is advancing the California Department of Education's broader goal of P-3 Alignment and teacher workforce development in public education. Case studies of two Santa Clara County public school districts will be presented depicting the evolution of P-3 vision articulation, board policies, approaches to assessment and curriculum, and authentic family engagement. Additionally, development of community-based early childhood education cohorts, administrator institutes, laboratory preschool learning walks, a TK teacher academy, and development of a PK-3 teacher credential program will be highlighted to illustrate inclusion and equity-focused teacher certification in partnership with community colleges and case study school districts._x000D_
