About the Project

Early Edge California (formerly Preschool California) and a panel of experts worked together to develop TKCalifornia to serve the needs of teachers and administrators as they implement transitional kindergarten. TKCalifornia is the result of a content creation and a review process led by 20 experts from across the state, including local school districts, county offices of education, researchers and state-level decision makers. Their expertise spans the areas of language and literacy development, early math, social emotional development and executive function, culturally responsive education and dual language acquisition.

The content and materials on this site are based upon the following key agreements and recommendations identified by our experts as critical to TK students’ learning:

  • reflecting  the continuum of development of all children, recognizing the breadth of their experience, and meeting them where they are to help them advance;
  • fostering warm, responsive relationships;
  • supporting family involvement;
  • offering examples of good teaching;
  • providing concrete guidance for teachers by showing how to sequence instruction and presenting easy-to-use resources;
  • helping teachers understand the use of formative assessment;
  • supporting teachers in differentiating instruction;
  • articulating with preschool and kindergarten;
  • focusing on the essential strands for teachers to build the foundation for kindergarten success; and
  • providing integrated learning and instruction.

TKCalifornia is operated and maintained by Early Edge California, a statewide nonprofit advocacy organization that is working to increase access to early learning opportunities for all of California’s children, starting with those who need it most. Early Edge California is proud to have sponsored Senate Bill 1381 by Senator Joe Simitian, which changed the kindergarten entry date and created transitional kindergarten, giving our youngest kindergarteners a head start that will yield significant payoffs in future academic success.

This project was created in 2012 and continues to expand and grow. For more information about the expert planning and advisory committees, leaders who contributed, and facilitators involved with Early Edge California (formerly Preschool California), please contact Hedy Andersson at TKCalifornia will continue to be developed over time, and Early Edge California looks forward to connecting with educators and implementers in the field to provide updated, high-quality resources to support TK implementation.

The development of this website was supported by the Heising-Simons Foundation, a family foundation dedicated to sustainable, research-based solutions in education, science, and policy.
