Transitional Kindergarten (TK) is the first of a two-year kindergarten program that is developmentally appropriate and aligned to the Preschool Learning Foundations. TK serves as a bridge between preschool and traditional kindergarten, utilizing a modified kindergarten curriculum taught by a credentialed teacher.
In 2021, legislation was passed that requires any local educational agency (LEA) operating a Kindergarten to also provide a TK program for all 4-year-old children by 2025–26. Starting in the 2022-23 school year, the average ratio in the classroom is one adult per every 12 students. Additionally, school districts and charter schools must maintain an average transitional kindergarten class enrollment of not more than 24 pupils per classroom for each school site.
Universal TK (UTK) means that by 2025–26, regardless of background, race, zip code, immigration status, or income level, every child will have access to TK as a quality learning experience the year before Kindergarten.

TK is a component of the Universal PreKindergarten (UPK) mixed-delivery system. While families may choose care from across this system, local education agencies (LEAs) are mandated to offer TK to all age-eligible children.
