Transitional Kindergarten 101
Created by the 2010 California law called the Kindergarten Readiness Act, and offered across the state, transitional kindergarten (TK) is an exciting educational opportunity to prepare children for kindergarten. Under the 2010 law, TK offers children with birthdays between September and December a developmentally appropriate curriculum taught by credentialed teachers from K-12.
The 2015-16 state budget further clarified the law to allow school districts to enroll 4 year olds even if they turn 5 after the December cutoff date, providing another local option to get more children ready for kindergarten. The Expanded TK approach gives districts an option to use a combination of local and Average Daily Attendance (ADA) funding to offer school readiness opportunities to children who might not otherwise have access.
The Kindergarten Readiness Act of 2010, signed into law by Gov. Schwarzenegger, changed the kindergarten entry date from Dec. 2 to Sept. 1 so that children enter kindergarten at age 5. The law phased in the new age requirement by moving the cutoff date one month a year for three years, and is now fully implemented.
The entry date change and the creation of TK address a longstanding need in California, as our children have historically started kindergarten at a younger age than kids in almost any other state – often without the maturity, social skills and early academic skills they need to succeed in kindergarten and beyond. At the same time, kindergarten standards and curriculum have changed over the years, and many of the skills children were once taught in first grade are now expected in kindergarten.
The youngest kids in a kindergarten class risk struggling academically, emotionally and/or socially. At their young age, some may have limited experience interacting with peers and teachers, while others may not yet know how to listen or follow a structured class schedule. Likewise, many 4 year olds in California still do not have access to high quality preschool that also provides these learning opportunities for our children. TK ensures that children have these pivotal skills, which are foundations to successful learning, when they begin kindergarten
Transitional kindergarten bridges the path between preschool and kindergarten and gives students the gift of time that will help them build a strong foundation for future school success. It blends social and emotional experience with academic learning, so that students not only learn essential pre-literacy, pre-math, and other cognitive skills, but also develop social and self-regulation skills needed to succeed in school and life. One out of every four kindergarten students in California will benefit from transitional kindergarten. As of 2014, TK serves 134,000 students each year.
TK is a win-win-win for children, families and schools.
- Children are better prepared to succeed.
- Families have an additional option to ensure their children enter kindergarten with the maturity, confidence and skills they need to excel.
- Schools benefit because children will be better prepared to succeed academically and less likely to be placed in special education or held back in later grades.
Research shows that the return on early investments in education is substantial. According to Deborah Stipek, professor at the Stanford University School of Education, “the cost is paid back many times over in reduced grade retentions, special education services and in lower expenditures for incarceration. Returns also come in the form of the increased productivity that results from higher levels of academic achievement and high school completion rates.”
As the first year of a two-year kindergarten experience, transitional kindergarten is fully funded by Average Daily Attendance (ADA) dollars. Your district will receive the same full ADA funding rate for TK students that you receive for all kindergarten students. In addition to core ADA funding, you also have other funding sources that can support your TK classrooms. Depending on how you structure the TK classrooms across your district (e.g. TK classes in select schools, TK/K combo classes, etc.), your funding approaches may vary.
For more information about TK funding, please see the Funding section in our Roadmap for administrators.
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 email@example.com. 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.
