Transitional kindergarten

Transitional kindergarten (abbreviated TK) is a California school grade that serves as a bridge between preschool and kindergarten, to provide students with time to develop fundamental skills needed for success in school in a setting that is appropriate to the student's age and development. Transitional kindergarten is also available in some schools in other states and can serve as a stepping-stone between preschool and kindergarten, especially for children with birthdates close to their state's kindergarten cutoff date.
