What is Transitional Kindergarten?

The Kindergarten Readiness Act is a law that changed the age for entrance into kindergarten in California. Children must now be five years of age for kindergarten by September 1. Transitional Kindergarten is the first year of a two-year kindergarten program for children whose fifth birthday is between September 2 and December 31. After students complete one year in Transitional Kindergarten, they return to their home school for kindergarten. This development program acts as a link between the flexible environment of preschool and the more structured academic setting of Kindergarten. Instruction focuses on literacy and numeracy, along with a strong emphasis on self-regulation and social engagement.
