Universal PreKindergarten (UPK) is an umbrella term that includes various forms of early learning and care, including: California State Preschool Program (CSPP), transitional kindergarten (TK), Head Start, district and local community-based preschool programs, early learning services for students with disabilities, private pay preschool, and expanded learning options to support access to a full day of services.
While families may choose care from across this system, local education agencies (LEAs) are mandated to offer TK to all age-eligible children.
Transitional Kindergarten (TK) 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 experiences 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 in life. TK is a component of the Universal PreKindergarten (UPK) mixed-delivery system.
In 2021, legislation was passed that requires any local educational agency (LEA) operating a kindergarten to also provide universal TK (UTK) programming for all four-year-old children by 2025–2026.
If a child turns five years old before September 1 of a given year, they are eligible for kindergarten. With Universal Transitional Kindergarten (TK), some four-year-old children may be eligible for TK.

With the expansion of Transitional Kindergarten, parents and families of four-year-olds across California are being presented with a unique range of educational options for their children.
Attending a high-quality early education program prepares children to develop critical social-emotional, cognitive, and early academic skills to be ready for kindergarten and beyond.
Finding the best option for your child takes time and research, and this section can provide a first step to learning more about the mixed-delivery system for California's four-year-olds. Remember - you know your child best!
