Transitional Kindergarten (TK) is the stepping stone between preschool and Kindergarten for California's schoolchildren. Since 2010, California has offered an additional year of Kindergarten to children with birthdays between September 2nd and December 2nd. Starting in 2022, California will begin expanding TK so that every four-year-old has the opportunity to attend a high-quality, developmentally appropriate Pre-K program when they are 4-years-old.

Early Edge California will be updating this site with resources and information about TK expansion as the process unfolds. Please be sure to check back frequently!
